New Horizons: Here and Now

On January 19^th 2006, a rocket lifted the New Horizons probe from the surface of the Earth, never again to return. At the time of this writing, the early afternoon of July 14^th 2015, the probe has completed its flyby of Pluto. For some NASA scientists, today is the most important day out of the three-thousand, four-hundred and sixty-three that have passed since launch. Those few thousand days include others with their own special importance, however. Through my office door I can hear the low, joyful roar of children playing here at the museum. Save for a handful of older kids, each of those girls and boys marks one of those days since January 19^th of 2006 as their birthday. For their whole lives, this piano-sized, plutonium-powered robot has been speeding through empty space at velocity of over nine miles per second away from the sun. And they are all still going strong, on paths unknown.

I was born in the year 1985 in Huntsville, Alabama. As a child, I made regular visits to the U.S. Space and Rocket Center located there; space exploration fascinated me then as it does now. My interest in rockets and astronauts dominated the design choices of my childhood bedroom, which featured a hanging mobile of the solar system. Pluto, then included as a planet (but what’s in a name?), was represented as a grey, mostly formless rock. That was our best guess at the time as to what it would look like. We now know, though just for the past few weeks have we known, that to have been an error. Pluto, as it turns out, is a ruddy world with varied geographic features. Certainly the original guess could have ended up being accurate, but as it stands this serves as a perfect example of my belief that inquiry and exploration are practices that enrich our world. Learning and understanding are value-adding courses of action. Pluto is a real place and, standing beneath it in the night sky, the only thing between it and you is the distance and a few miles of air. We now know what it looks like. We didn’t before.

The kids I work with on a daily basis as the science educator of this museum are in the business of exploring the universe around them. They are aligned in this sense with the grownups of the world who have gotten jobs as scientists, and certainly some of the voices I hear even now outside my door will one day deliver presentations at important academic conferences or discuss the design of an experiment late into the evening with researcher peers. Regardless of job title, however, it is my personal and professional goal that visitors to our museum, young and old alike, gain some kind of new appreciation for this world and those around us. Science is one of the tools that I have to assist with that, and a wonderful thing about using science is the fact that it can show us how interconnected everything truly is. The gravity on Pluto is not as strong as Earth’s, but it follows the same rules as the gravity on Earth. Understanding how the radio waves we use to send commands and hear from New Horizons work also leads to an understanding of the light that we use to see. The same rules of color-mixing that the probe uses in order to take photographs is taking place with paint and brushes right now a few yards from my office. No matter your starting point, seeking to understand the universe can take you to unexpected places. All roads lead to everywhere.

In just a few short weeks we will temporarily close our doors to undergo a renovation. Upon reopening, there will be a dedicated science area that we are calling Step Up to Science. Another new addition to the museum will be our climbing globe, 14 feet in diameter. If we were to create a scale model of the solar system based upon that as our Earth, the moon would be about 3 feet, 10 inches across and located, on average, 422 feet away. The sun would be 1,530 feet across and a bit over 31 miles away. Pluto, for its part, would be 2 feet, 7 inches across and almost 1000 miles away from our front door. And New Horizons itself would be an invisible mote of dust drifting by, only ever having gotten as close as 14 feet to Pluto’s surface in our scale model, taking five seconds to move an inch. One day in the not-so-distant future, kids sitting at our Science Bar will draw up maps of our scale model solar system. Or they will program a robot. Or they will toddle right past me and to the lunch tables, still waiting for the day or the question or the experiment that piques their interest. We will be here, just as Pluto is there. I look forward to the adventure!

All the Cinderellas

For our last little peek behind the pages of the fairy tales in our current exhibit, Once Upon a Time, we’d like to celebrate one of the best-known of them: Cinderella! The beauty with the special slipper has a very, very long lineage. Stories about her, or women very much like her, have been traced back hundreds of years, to China, Greece, and Egypt.

The Greek-Egyptian version of Cinderella is most likely the earliest, although it lacks many of the elements that are more familiar to us from the European-derived stories of the 1700s. In this tale, the heroine is named Rhodopis, and she was one of many servants of a Greek businessman and politician named Xanthes. He had taken a party to Egypt for business, and Rhodopis, bathing in a spring, had one of her slippers snatched up by an eagle, who then dropped it in the lap of the King of Egypt. The king took this as a sign from the heavens and searched everywhere for the slipper’s owner. Rhodopis, also known as Rhodope and as Doricha, was most likely a real woman, a courtesan (or “hetaera”) who lived about 2600 years ago, but the story about the shoe was probably a tall tale, and we can thank her contemporary, Aesop, for that.

More than a thousand years later, the popular tale had made its way to China. Tuan Ch’êng-shih wrote of a heroine named Yeh-Shen, and her story is closer to the version that we know. Yeh-Shen longs for happiness and marriage since her stepmother is so cruel, and she has some supernatural help from a magical fish who grants her wishes. Yeh-Shen attends a ball wearing a beautiful dress and slippers made of gold, and leaves one behind, in the hands of a charming king, when her allotted time expires.

Yeh-Shen and Rhodopis stories continued to be told, with different names, as the centuries passed, with dozens more iterations than we have room to discuss here. In 1697, Charles Perrault’s version, “Cendrillon,” was published, and it’s pretty much the final form that we know it today. Earlier European versions had replaced the magical benefactor with a kind godmother, but Perrault made her a fairy godmother for the first time. She transforms a pumpkin into a carriage, makes the slippers from glass, turns mice into horses, and so on. Basically all the elements of Cinderella that we all recognize are present in Perrault’s version, which has as strong a claim as any to being the most popular of all fairy tales.

Perrault’s was not the final version, of course, because as we’ve discussed, fairy tales are always changing and evolving. In recent years, Hollywood movies like Snow White and the Huntsman and Maleficent have given classic fairy tales a darker edge, but the Cinderella story was taking on heavier overtones quite early on. In 1812, the Brothers Grimm, Jacob and Wilhelm, published their seminal collection of European tales, and the Cinderella version that they included, entitled “Aschenputtel,” is much darker than Perrault’s and all the variants that followed it.

What interests me about Cinderella, though, is that the bleak overtones that some writers and folklorists have added to the story don’t actually seem to stick. As we noted in the first of these features, about Jack and the Beanstalk, many fairy tales actually thrive with a little color and backstory and discussion of motivations, even if it’s sometimes darker. Cinderella, however, shrugs off anybody’s attempts to darken it. Perhaps because the core of the story is so bright and happy, and its tale of wish-fulfillment is so encouraging and promising, that darkness just doesn’t belong to it. Cinderella is arguably the most popular fairy tale in the world, and the happiest.

Red, White and Blueberry Recipes!

In honor of the Fourth of July, this week we challenged ourselves to create a full meal based on three different colors: Red, White and Blue. It turns out that the internet is chock-full of patriotic-themed recipes. Because we have a dedicated staff (who like to eat!) we whittled down the sixty-gajillion available color-themed ideas we found into a somewhat healthy and nutritious three-course meal with lots of blueberries. Well, the dessert’s not the healthiest thing we could come up with, but it sounds delicious!

Let’s start with a “Patriotic Salad” with quinoa and berries, as found at Yummy Mummy Kitchen.

5 ounces arugula or other salad greens
3 cups cooked, cooled quinoa
1.5 cups blueberries
1.5 cups raspberries
Sliced watermelon cut into stars with a cookie cutter
favorite salad dressing, served on the side

On the bottom of a medium trifle dish or clear salad bowl, arrange one third of the greens. Top with half the quinoa, all but 1/4 cup blueberries, the remaining quinoa, another third greens, all but 1/4 cup raspberries, and top with the remaining greens. Arrange the remaining 1/2 cup berries over the top. If using watermelon stars, tuck into the sides and arrange on top of the salad. Make this salad up to 5 hours in advance, cover with plastic wrap, and refrigerate. Serve dressing on the side.

 

For the main course, let’s continue with blueberries since they are in season right now, and enjoy a Chicken and Blueberry Pasta Salad, from Eating Well:

1 pound boneless, skinless chicken breast, trimmed of fat
8 ounces whole-wheat fusilli or radiatore
3 tablespoons extra-virgin olive oil
1 large shallot, thinly sliced
1/3 cup reduced-sodium chicken broth
1/3 cup crumbled feta cheese
3 tablespoons lime juice
1 cup fresh blueberries
1 tablespoon chopped fresh thyme
1 teaspoon freshly grated lime zest
1/4 teaspoon salt

Place chicken in a skillet or saucepan and add enough water to cover; bring to a boil. Cover, reduce heat to low and simmer gently until cooked through and no longer pink in the middle, 10 to 12 minutes. Transfer the chicken to a cutting board to cool. Shred into bite-size strips.
Bring a large pot of water to a boil. Cook pasta until just tender, about 9 minutes or according to package directions. Drain. Place in a large bowl.

Meanwhile, place oil and shallot in a small skillet and cook over medium-low heat, stirring occasionally, until softened and just beginning to brown, 2 to 5 minutes. Add broth, feta and lime juice and cook, stirring occasionally, until the feta begins to melt, 1 to 2 minutes.
Add the chicken to the bowl with the pasta. Add the dressing, blueberries, thyme, lime zest and salt and toss until combined.

Finally, let’s have a Red, White and Blue dessert, from the blog of Taste of Home magazine.

2 packages (8 ounces each) cream cheese, softened
1/2 cup sugar
1/2 teaspoon vanilla extract
1/2 teaspoon almond extract
2 cups heavy whipping cream, whipped
2 quarts strawberries, halved, divided
2 quarts blueberries, divided

In a large bowl, beat cream cheese, sugar and extracts until fluffy. Fold in whipped cream. Place a third of the mixture in a 4-qt. bowl. Reserve 20 strawberry halves and 1/2 cup blueberries for garnish.
Layer half of the remaining strawberries and blueberries over cream mixture. Top with another third of the cream mixture and the remaining berries. Spread the remaining cream mixture on top. Use the reserved strawberries and blueberries to make a “flag” on top.

You’ll have plenty left over after this one, but on the other hand, you could certainly adapt this as a single-layer recipe for your family. If you’re planning to take a dessert to a July 4th party, on the other hand, this looks like a treat fit for all the founding fathers!

 

Professor Labcoat celebrates National Maker Week!

Hello everyone! Professor Labcoat here. It’s National Maker Week, and today I’d like to show you how to learn about electrical circuits using play dough!

We use electricity to power all kinds of things every day. Electricity is what we call it when charged particles are pushed around, and we can make, or “generate”, electricity in many different ways. The power plants that generate electricity for entire cities use huge magnets to push electricity through the big wires that we see along the side of the road, solar panels use light energy from the sun to push electricity around, and batteries use chemical reactions.

The materials needed for this experiment are 4 AA batteries, a light emitting diode (LED), and some play dough that’s made with salt. There are many recipes online for play dough; I made some by combining 2 cups of flour and ½ cup of salt with roughly 1 cup of water added slowly. Food coloring can make for a fun color addition. You can also add a couple of teaspoons of oil and a teaspoon of cream of tartar to help with the texture, or just use some of the store bought variety!

Finding a light emitting diode (LED) might be a little tricky. I took apart a small finger-mounted flashlight to get mine. These parts are also available at many electronics stores or online for less than a dollar apiece.

The first thing we need for our circuit is something to generate the electricity. The chemical reactions inside the batteries will do this for us by pushing charged particles from one side of the battery to the other. We want all the push to go in the same direction, so we need to line up our batteries end-to-end and pointing in the same way. A little ball of dough acts as a conductor between our batteries. We need these batteries to push the electricity hard enough to make our LED light up. We measure the push of electricity in units called “volts”. Each battery gives 1.5 volts worth of push to the electricity, so four in a row give 6 volts of push total. This should be strong enough to move electricity through both the dough and the LED.

The play dough is our conductor. Instead of electrons moving through metal, our electricity will take the form of tiny pieces of the salt (called “ions”) moving through the water in the dough. It takes more energy to move ions through dough than to move electrons through metal, so dough wouldn’t make a very good extension cord. It is safe to use with the batteries, however, because it won’t heat up as a metal wire would. Plus, it’s fun to squish!

Electricity can only move through LEDs in one direction, so you might need to switch yours around a little bit before it works. Once you’ve got a circuit together, you can try out different things! What happens if your dough rolls are fat and short? Skinny and long? Does it change the brightness of your bulb?

There are many people who have created many great lessons to go along with this kind of circuitry. Check out the wonderful work of the University of St. Thomas and their “Squishy Circuit” homepage!

I hope you enjoy making your play dough circuit and learning about electricity! There are many wonderful things that we can use science to build and understand, and Makers the world over have created many fantastic resources for Young Makers!

Take care!

First Lady of Atlanta Helps Kick Off Mayor’s Summer Reading Club

It’s summer, and one of the great things about summer in Atlanta is the Mayor’s Summer Reading Club. We’re happy to once again be a partner, and a host for their kickoff event. The fun starts at 10am this Saturday morning, and we’ll have readings and crafts all day long! Plus, a special reading by First Lady of Atlanta Sarah-Elizabeth L. Reed and other special guests.

At the Museum, our staff works hard to promote literacy, because the studies show that many children don’t read and exercise their mental muscles during the summer months as much as they do when school’s in session, meaning that they will start the next grade a few weeks or months behind, and often struggle to catch up. We hope that all parents will participate in combating summer reading loss, and keep kids engaged in books.

So, where does the Mayor’s Summer Reading Club come in? Well, from their site, “The program designates a city- wide book choice for infants, for children ages 2-4, and for children ages 5-8 to share with families at no cost to them. Throughout the summer, libraries, museums, farmers’ markets, and other institutions in Atlanta will hold “book club reads” to model research based methods of reading books with children and will host enrichment events based upon the stories. The books will come to life as children enjoy arts and crafts activities, drama exercises, and other hands on activities designed to make the language in the stories meaningful to children.”

“The Mayor’s Summer Reading Club has helped thousands of Atlanta’s children and family members improve their literacy skills and ignite their passion for reading,” said Mayor Kasim Reed. “Now in its third year, the program, supported by my administration, valuable partners and Atlanta-based organizations, is increasing its reach, and inspiring more young ones to fall in love with reading. Research shows that children who read during the summer months perform better on achievement testing and are better prepared for the school year. It is my hope that the program continues to grow, and further support one of my top priorities—investing in our city’s children.”

For the third year in a row, the Rollins Center for Language and Literacy at the Atlanta Speech School have written a new adventure starring Amari, our city’s favorite young heroine, for children aged 3-5. In the previous books, Amari has visited Zoo Atlanta and biked on the Atlanta BeltLine. In her newest story, Amari’s Shining Moment, she and her neighbor, Andres, visit the children’s village of the Dogwood Festival and see a performance of “The Shoemaker and the Elves,” inspiring them to recreate the stage and perform the play for their entire neighborhood. Amari uses the skills of problem solving and determination she learned through her first two adventures to help Andres get over his stage fright.

(Say, isn’t that something? “The Shoemaker and the Elves” is one of the fairy tales that are spotlighted in our current featured exhibit, Once Upon a Time!)

The First Lady of Atlanta, Sarah-Elizabeth L. Reed, will be here to share Amari’s adventures to our guests Saturday morning. She will be here to read the book at 11 am. The other books featured for the club this year are, for infants, The Pigeon Has Feelings Too by Mo Willems, and, for readers aged 5-8, Dad, Jackie and Me by Myron Uhlberg and Colin Bootman. Find out more about the books at the Mayor’s Summer Reading Club! All of our guests on Saturday will get to take home books for free! We look forward to seeing you here at the Museum on Saturday.

Schedule of events for Saturday, June 6

• 10 AM : Craft time
• 11 AM : First Lady of Atlanta, Sarah-Elizabeth L. Reed to read Amari’s Shining Moment
• 12 PM : Imaginators bring to life Dad, Jackie and Me by Myron Uhlberg

• 4 PM : Construction Aerobics

All events are included with the price of admission and, as always, members are free.

Giving children time to explore

Earlier this week, in The New York Times, David Kohn wrote about children and learning, and although he didn’t use the exact phrase that we do here, “The power of play,” it still resonates throughout his story. Children learn through hands-on exploration. They need to set their own pace, and they need to be given constant opportunities to use their imagination, create rules and boundaries, and interact with other children.

From Kohn’s story, “Play is often perceived as immature behavior that doesn’t achieve anything,” says David Whitebread, a psychologist at Cambridge University who has studied the topic for decades. “But it’s essential to their development. They need to learn to persevere, to control attention, to control emotions. Kids learn these things through playing.” You can’t teach these things, and you certainly can’t test them. Children will observe and respond and learn at different levels, but even the silliest-looking play has so much more going on than can be quantified, objectified, and compartmentalized.

Kristin Tillotson, writing in The Minneapolis Star-Tribune, uses an analogy familiar to anybody who’s read the Sunday funnies: when kids explore, it looks like one of the characters in Bil Keane’s The Family Circus, taking off on their meandering, “serpentine” paths, connecting points A and B by way of every other possible letter. We see this a lot with our regular guests. Sometimes, they arrive and the child has a very specific idea about which area of our Museum they’d like to explore and go straight there, but just as often, we’ll see a child absolutely determined to climb in our treehouse, but only after winding around through every other place they can find and writing their name on our paint wall first.

It’s pretty amusing watching children do this, but it’s also perfectly natural behavior. Tillotson calls this “informal meandering” an organic way to learn, and Marjorie Bequette, director of evaluation and research at the Science Museum of Minnesota, agrees, pointing out that children respond to being in charge of the adventure.

Even looking around and observing things in a space, whether it’s one you are familiar with or one that’s brand new, has so much value. In her story, Tillotson mentions that some New York police officers receive training in observation at the Museum of Modern Art. I read some more about that in a 2009 story at Smithsonian, and learned that there is a program where veteran officers get an early morning class in observation. It’s evidence for Tillotson’s theory that museums really are mind-expanding, and that, whether you’re an adult or a child, the experience at any museum is one where the observer is continually learning.

When you next visit us, once you catch up with your child after their “serpentine” tour of the place, try spending a few minutes asking questions about what they have explored and observed. What does the Moon Sand feel like? How many lights do they see? What do they notice about colors and shapes? Perhaps they’ll have some questions about what you have seen and explored as well, so keep your eyes and ears open as you play with your children… you may just learn a thing or two yourself!

Fairy Tales Thrive in the Telling

Ask a dozen academics why fairy tales have such staying power and resonance and you’re sure to get a dozen different answers. Folk tales go back centuries, and the details shift and change in the telling. As books became available, and later, films were made to adapt the stories, they took on new details, additional characters, and often songs to pad out the running time. But even before the possibilities of print or animation, the tales that we know and love from our childhood had evolved and changed as the stories moved around different cultural groups.

We’re thinking about legends and folk tales a lot this week because we’re so happy to be welcoming back a really popular exhibit, last seen on the Museum floor in 2011, Once Upon a Time…Exploring the World of Fairy Tales. If you missed it the last time around, you’re in for a treat. From an African jungle to a giant’s castle, this unique and educational exhibit focuses on the power and significance of fairy tales throughout history and from around the world. Children will enter an enchanted storybook kingdom where they’ll learn the meaning and history of tales they’ve known all their lives, and others that may be new to them.

The featured tales are “Anansi and the Talking Melon,” “Beauty and the Beast,” “Cinderella,” “Jack and the Beanstalk,” “Lon Po Po,” “The Shoemaker and the Elves,” and “Thumbelina.” Over the next few weeks, we will be exploring the origins of all of these fairy tales, starting with “Jack and the Beanstalk.”

“Jack and the Beanstalk” is correctly called an English folk tale, dating to the early 1800s, but the metaphorical “beans” came from all over Europe before the version of the tale that you might find most familiar took “root.” The concept of climbing some kind of plant life to reach an otherwise impossible-to-access realm in the sky is centuries old. Norse mythology considered a gigantic tree called Yggdrasil whose branches were in heaven, as does Buddhist tradition, where it is described as a Bodhi tree. The Book of Genesis offered the tale of Jacob’s Ladder, which also reached heaven. The “Jack and the Beanstalk” section of the exhibit features a small “beanstalk” for children to climb, which is really quite fun. Don’t worry, parents, the beanstalk doesn’t stretch quite so high that your children will vanish into the clouds!

Germanic folklore is positively packed with giants and ogres, most of whom selfishly guard treasure and need to be outwitted or defeated. That makes them the perfect antagonist for a traditional, clever, and sharp-thinking hero. England in the 15th and 16th Century brought us just such a hero in a bright young commoner, typically called Jack, who appeared in dozens of folk tales. (There’s a “house that Jack built,” for example.) Mix in a little Shakespeare – the giant’s traditional warning cry of “Fee, fi, fo, fum, I smell the blood of an Englishman” comes almost directly from King Lear – and the basic form of the story is pretty typical of 18th Century folklore from the British Isles.

One of the great things about fairy tales is that despite the usual conclusions like “The end” or “And they all lived happily ever after,” they’re still evolving and adapting, with no end in sight. Jack himself has been replaced in dozens and dozens of adaptations over the last seventy years by everybody from Mickey Mouse to Ernie to Nintendo’s Mario to the casts of The Goodies and The Magic School Bus, and they all bring their own spins to the story, making anybody who remembers the version that they heard or saw then retell it differently to their own children. How many trips did Jack make up to the giant’s castle, anyway? Was it just the one, or did he pilfer all the giant’s treasure over the course of a week? Was the giant a lone miser, or did he have a wife who helped Jack bedevil her cruel husband?

And is it really fair to root for Jack, stealing the giant’s gold and ensuring his grisly end? Some adaptations, including a 1952 Abbott & Costello comedy, include some rather important details about Jack and his community’s poverty, blaming the giant for stealing all the area’s gold. On the other end of the spectrum, a 2001 TV miniseries directed by Brian Henson, shown in America on CBS, painted Jack as the villain of the piece, and sent his descendant back to the kingdom of the giants to return the stolen property and atone for the crime.

How will your child interpret the story of “Jack and the Beanstalk”? How will you retell it to him or her at bedtime? We’re sure you will add a detail or two, and your child will tell a slightly different version to his or her own kids down the line as the stories continue to evolve with each new generation.

Once Upon a Time… Exploring the World of Fairy Tales opens this Saturday, May 16, and runs through July 26. We hope that you’ll come and play with us!

Farmers Markets Around Atlanta

Have we had enough of these April showers yet? If you can see the billboards through all the rain, you may have noticed that some of the region’s large farms have begun strawberry picking. Mercier Orchards in Blue Ridge and Washington Farms near Watkinsville are getting their crops ready, which is a good sign that the various farmers markets around Atlanta are up and running, with fresh fruits and vegetables, salsas, juices, meats, honey, and all sorts of other local vendors selling directly to customers.

My family loves shopping at the Marietta Square Farmers Market. It is open Saturday and Sunday mornings and brings out vendors selling the most wonderful milk, cheeses, jams, and veggies along with the omnipresent King of Pops cart and a local girl who pays for her horse’s boarding fees by selling the best limeade you’ve ever had. Marietta Square Farmer’s Market is a favorite with my family, but there are several other established farmers markets in the city. I asked some of our Children’s Museum of Atlanta staff which ones they like to visit.

The venerable Your Dekalb Farmers Market was many people’s favorite. Hajar Lateef, from our Visitor’s Service staff, told me that she loves going to get all the vegetables and fruits from different parts of the country, and that the selection is unbeatable. “It’s like a candy store!” she exclaimed. Development assistant Alicia Robertson is also a big fan, and particularly enjoys visiting one particular vendor among the ones who sell prepared foods at the market. She loves buying fried garlic plantains from one of the sellers.

Toy Expert Lucreacia Henderson only just started going to Your Dekalb Farmers Market at the beginning of the year. She says “It’s the one place I can find all the natural and organic stuff that I’m looking for in one place,” singling out a particular coconut oil as a favorite. But it’s not all herbs and oils for her, because one vendor makes a particularly amazing peanut butter cookie. “You can see the peanuts in it! I’ve brought home his whole stock!”

While Your Dekalb Farmers Market is the largest in the city many  of our employees visit the smaller ones in their own neighborhoods. Courtney Strickland, also from our Visitor’s Service team, enjoys the “quaint” Sandy Springs Farmer’s Market along with what appears to be all of her neighbors. “If you’re in Sandy Springs, you go,” she told me. Apart from the vegetable sellers, she’s particularly fond of buying fresh, homemade bread and honey.

On the east side of town, Michelle Cherubim enjoys the Stone Mountain Farmer’s Market, and is glad that she lives nearby, because she believes that it has the most variety of any in the city, with foods from many different countries. Daniel Lomax, our newest Imaginator, is particularly fond of the venerable Sweet Auburn Curb Market, which first opened almost a hundred years ago. As writer Christiane Lauterbach explained in a story for Atlanta Magazine last year, manager Pam Joiner reinvigorated Sweet Auburn in 2005 by bringing in small and eclectic restaurants to draw crowds to the produce and the meats. Daniel tells me that he can’t find fresher fish in Atlanta than what’s available at Sweet Auburn.

One thing’s definitely certain: farmer’s markets are hugely popular. So, make sure you get to your local market early enough to beat the crowds and grab some great deals!

Staff Pick: Earth Day Toys

Earth Day is right around the corner and here at the Museum we love to encourage healthy planet habits that take care of Earth! We will be celebrating Earth Day this weekend with Novelis on Saturday and Sunday. This will be the 45th anniversary of the Earth Day movement, meaning 45 years of “broadening the base of support for environmental programs, rekindling public commitment and building community activism around the world through a broad range of events and activities”. All the environmental activities and lessons are very important to pass down to our children.

We currently have some awesome items in our Museum Store that are definitely Earth Day appropriate. Our staff picked out their 3 favorite Earth Day items from the store and shared a little bit about why they liked the particular items.

Kareen Dames, manager of museum sales, recommends:

The Busy Bug Gardens is my favorite thing in the Museum Store because I love butterflies! This awesome little kit allows children to learn about gardening and enjoying the site of Monarch butterflies and hummingbirds, both of which are attracted to the Purple Coneflower that will sprout from the seeds in the kit. I also like that this is an activity that can be done inside or outside.

Debbie Palay. director of development, recommends:

I would recommend spending time with the Solar Print Kit. These kits are an excellent way to teach kids about the power of the sun and the chemical process behind the imaging that takes place on the special paper. This is an activity that is suitable and appealing to both boys and girls and can be a fun way to spend a sunny afternoon.

Cayce Dunn, digital marketing manager, recommends:

I love the Recycled Paper Beads kit! I love doing crafts and the fact that this craft also recycles was definitely a two-for-one plus! Making paper beads always seemed tedious and a little tiring by hand, but this gadget that fits perfectly on a recycled water bottle looks like a super simple and efficient way to make beads. Not to mention, the added bonus of the recycled water bottle being used as a container for the finished beads. I love the idea of showing children how old magazine pages can be used to create fun jewelry and awesome one-of-a-kind handmade gifts. Recycling is definitely a planet-friendly way of using your imagination to figure out how to use the most out of the stuff you have!

If you plan on visiting us to celebrate Earth Day, drop by the Museum store to check out these items. They would make awesome gifts or just a fun activity to take a part of the Museum and the message home with you. Earth Day celebrations at the Museum begin Saturday, April 18th at 12 PM. The fun will continue Sunday, April 19th at 3:00 PM. Check our Programming Schedule for more info of the days happenings!

Science Around Atlanta: Physics & Roller Coasters

Hello girls and boys! Professor Labcoat here!

In my last blog post, I said, “No matter what you’re interested in or what question you have, there’s probably a scientist somewhere trying to figure it out.” That’s very true, because science is a way to learn about the world around us and everything that’s in it. There are all different kinds of scientists who are interested in all different kinds of things! You can learn more about almost anything that you’re interested in by using science.

The other day, my friend Cayce got to go to Six Flags Over Georgia to try out their Batman: The Ride roller coaster…backwards! She had a lot of fun, and even got a video of her on the ride! I decided that it’d be fun to use her video to talk about the science we can learn from roller coasters.

When I was a kid, I wasn’t a big fan of roller coasters, but I like them more and more these days. Roller coasters do some pretty cool things. They can go very fast, turn upside down, and make you dizzy very quickly. It seems pretty complicated at first, but science can help us to understand complicated things!

To figure out roller coasters, we need to think about things called “forces”. A force is a push or pull on something, and this can happen in a lot of different ways. When something pushes or pulls on something else, we say it’s “applying a force”. For example, if you push someone on a swing, you are applying a pushing force to them. If the wind blows your hair around, that’s a force the wind is applying to your hair. And you’re stuck to the ground because the earth’s gravity is applying a force pulling you downward!

Some kind of force is needed to make something start to move, slow down, or change direction. We might not always realize this is what’s going on, however, because forces can show up in places that we don’t always expect.

For example, if you throw a beanbag, you push on it with your hand to apply the force to get it to start moving. Once the beanbag leaves your hand, it’s not getting any more force from you. There are still forces on the beanbag, though, and these forces work against the force of your throw! One force is a push back from the air the beanbag is moving through. This slows the beanbag down a little bit. Another force is the force of gravity. This pulls the beanbag towards the ground. Finally, when the beanbag hits the ground, the ground applies a force that stops it from moving!

This all seems very normal to us because we deal with these kinds of forces in our everyday lives. It took scientists a long time to figure out all of these forces are happening, because everybody was so used to them! But, if you were an astronaut in space far away from the earth with no air around you, no ground under you, and no gravity to speak of, and you threw a beanbag, it would keep going in a straight line for thousands of years! It wouldn’t have any other forces around to change how it moved.

So, what does this have to do with roller coasters?

A person riding a roller coaster, such as my friend Cayce, moves in a lot of different directions at different speeds. All these changes in speed and direction mean that there are a lot of forces changing the way the person is moving. When we ride a roller coaster, we feel these forces as pushes and pulls from the straps on our seats.

One of the most important forces for roller coasters to work the way they do is the force of gravity. Just like our beanbag example, where the force from your hand gives the beanbag the push to get it started, gravity provides the force that moves you around on a roller coaster. You see, there are no motors or engines on roller coaster cars. What happens at the start of almost every roller coaster is the ride pulls you up a tall hill, and then pushes you off the edge. You can see this in Cayce’s video: at the beginning, she and her sister slowly move up a hill. The moment they start moving after that, the only force that’s making them move faster is the force of gravity pulling them down!

The first hill of a roller coaster is always the tallest part of a roller coaster, because after gravity starts to pull you around, it won’t be able to make you move to a taller place than where you started. In much the same way, if you drop a bouncy ball (without throwing it at the ground!), it will never bounce higher than where you dropped it.

Roller coasters are designed to make sure that the forces they apply to the riders aren’t enough to hurt them; this is a big part of the reason why you have to be a certain height to ride roller coasters! The seats are designed to make sure that they push and pull on the right parts of people. When roller coasters go upside down, the forces applied to the riders make sure that gravity can’t pull them out of their seats. And, sometimes on roller coasters, as the forces are changing around, you don’t feel any forces at all! This is called feeling “zero-g”. The “g” stands for “gravity”, and this means that you feel weightless. A feeling of weightlessness is what astronauts in the International Space Station experience! It’s only during special occasions that we get to have that sensation on the earth, which is one of the reasons roller coasters and other fun amusement park rides are so exciting!

I hope you enjoyed learning about roller coasters with me, and I look forward to talking about all sorts of other things with you in this space. Take care!
