En Garde! DIY Peep Jousting!
- Patria Lincoln Posted On Mar 29, 2018 | Easter
First of all, this activity provides for plenty of cheering and laughs, but is truly a science experiment on the molecular level. Peeps fresh out of the package are best, but perhaps keep the experiment interesting by changing the state of the Peeps. For example, the marshmallow candy was soaked in water and vinegar and one Peep was left out to become stale. Will it make a difference?
But first, let’s have the fresh Peeps face off. Positioned on a paper plate, stick a toothpick in each Peep, while their “swords” just slightly touching.
Place in the microwave and set for 30 seconds.
Let the jousting begin!
Looks like the green Peep bested his pink challenger.
What happens will happen with the Peep soaked in white vinegar?
There was no clear champion. The children noticed that the vinegar Peep was just as likely to puff up in the microwave, but much more melt-y afterward. This is because sugar dissolves more slowly in vinegar, so the sugar isn’t as likely to be broken down, as in say, water. Which brings us to our next trial…
The H20 Peep was more soaked with water, making it puff up less and barely move. This Peep didn't move as much and was left open to being poked. Lastly, the stale Peep was not a great contender. Completely separating in the microwave, the stale Peep did not stand a chance against the fresh one.
The science behind Peep Jousting:A Peep is made up of itty-bitty air bubbles that are encapsulated by thin walls of gelatin and sugar syrup. When faced with heat, those air bubble started to really move, then turn to steam. That steam fills up those air pockets very big, causing the Peep grow large. The peep then grows smaller when the heat source is removed. Where the toothpick sword lands on its opponent seems simply based on where it was placed in the Peep.

Ultimate STEM Day Activity Bundle! National STEM Day is November 8 – a day designated to the wonders of science, technology, engineering, and math. To help you celebrate STEM in style, we’ve put together three of our very favorite, holiday-themed STEM smarts & crafts activities perfect for your Thanksgiving Day festivities and winter break fun.
Simple Physics Turkey Races
Add some get up and go to your gobble gobble with these crazy-fun turkey races perfect for perking up the party on turkey day!Here’s what you’ll need:BalloonsConstruction paperTapeStringPlastic strawsChip clips or binder clips
Here’s what you’ll do:Blow up one balloon per racer but don’t tie off the ends. Instead, twist the end, then attach a kitchen “chip clip” or binder clip to keep the air from escaping.
Cut your construction paper into feathers, waddles, and googly eyes and tape the pieces to your “turkeys”.
Set up your race course by placing two chairs about 8 feet apart (you’ll need one set of these chairs for each racer). Cut a 9-foot section of string for each racer and tie the loose end of a length to one chair.
Thread a straw through the untied end of the string, then pull the string taught and tie to the opposite chair.
Using tape, attach the top, center of the balloon to the straw. Make sure to line the straw up with the release point of the balloon, for straighter, faster flying.Pull the balloons back so the ends are touching the chairs, pinch the balloons above the chip clips, and remove the clips.
Call “On your marks, get set, GO”, let go of the balloons, and watch as your turkeys race to the finish line!
Let’s talk turkey about physics! Remember that for every action, there is an equal and opposite reaction (thanks, Newton!). When you blow up the balloon, you are filling it with air. When you release the chip clip, you are releasing the air, creating pressure out of the back of the balloon. This release creates an equal and opposite pressure on the front of the balloon, propelling it forward. Crystal Snowflake Christmas Ornaments
Celebrate the coming winter with crystal snowflakes you make yourself!What You’ll Need:Pipe cleanersBoraxFood coloringWide mouth glass container like a measuring cupPencil, craft stick, or spatulaString or an extra pipe cleaner
What You’ll Do:Cut your pipe cleaners in half, then cut some of them in half again.
Twist the pieces together to form one-of-a-kind snowflake patterns, making sure that your snowflakes will fit into your container without touching the sides or bottom. (Trim the ends with scissors if need be.)
Tie one end of the string to the center of your snowflake and the other to your pencil or craft stick and check to make sure your snowflake will fit without touching the sides or bottom of your container.
Bring a pot of water to a boil. For every cup of water you pour into your container, add 3 tablespoons of Borax and stir (this is a job for a parent as the water is boiling hot!). Add more Borax and stir to dissolve, continuing until the water won’t accept any more Borax (it’s okay if there’s some left in the bottom of the jar). Then add a few drops of food coloring and stir.
Hang your snowflake in the water by balancing your pencil or craft stick across the top of the jar. If your string is too long, twist it around your pencil until it keeps the snowflake from touching the bottom.
Leave your snowflake overnight. Carefully pull your snowflake out of the jar and shake off the excess crystals to reveal your crystalized snowflake!
Borax can be beautiful! Hot water molecules are moving really quickly, which leaves room for the Borax to dissolve between them. As the water cools, the molecules move closer together, “squeezing” the Borax out. Winter Marshmallow Dens
Turn those cocoa fixin’s into a science lesson about the winter habits of some of your kids’ favorite animals with this tasty activity!What you’ll need:ToothpicksMarshmallowsPaperCrayons or markerSnowy Animal ToysWhat you’ll do:Ask your kids to imagine where they might go to hibernate if they lived out in the wild. Have you kids draw their ideas on paper.
Set out the marshmallows and toothpicks and challenge your busy builders to construct their drawings.
Once they’re done, see if someone can build a snow den, an igloo, or a walled fort. The possibilities are endless (and delicious!).
With snow covering the ground, fewer plants are growing, which means less food for hungry animals like bears, bats, and squirrels. Hibernating slows down these animals’ metabolisms and reduces their body temperatures, which means they need less energy to survive and can go without eating for several months at a time. Hibernating animals need a safe, hidden spot to snuggle down for the winter months, similar to the caves and burrows you just built! HAPPY STEM DAY!

Celebrate Astronomy Day with Kids
Each year Astronomy Day is celebrated worldwide. The stars have fascinated humanity for literally centuries, and even to this day captures the imagination of kids of all ages. Celebrate this event with them this year and don't worry if you don't own any expensive telescopes. These DIY activities use real life discoveries to inspire your little astronomers!
Track the Phases of the Moon
Bone sticks from across Europe and Africa dating back as long ago as 35,000 BCE that tracked the moon’s phases. Use a simple number line with your kids to track the phases of the moon over the course of a month, from full moon and back again. Do it for several months and see what patterns they begin to observe.
Depict a Celestial Phenomenon
A celestial phenomenon is a astrological event that involves one or more objects. The earliest example depicted was discovered in Germany in 1999. The Nebra Sky Disc dates back to 2000 BC and it depicted a star cluster, phases of the moon and the rising sun.
Use a black paper plate, or even just black paper, and encourage your children to depict their own star formations. If they can’t stay up to observe them at night, project some indoors with this Shining Stars Projector.
Astronomy to Keep Time
The Chinese astronomers kept detailed observations beginning about 600 BC, for the primary purpose of timekeeping. Their records allowed them to predict eclipses, and include the first record of events such as supernovas and comets.
On the other side of the world, the Mayans developed their own astronomical tables for predicting the phases of the moon, eclipses, and the appearance of the other planets. They used these and the cycles of the Sun, the Moon, Venus, Jupiter, Saturn, Mars and constellations to establish the Mayan calendar.
All of the above astronomy was without a telescope, and you can still observe these astronomical events with your kids today. Check out this astronomy calendar and pick a full moon, eclipse, planetary event, or meteor shower to observe as a family.
Try this simple astronomy experiment to help kids as young as preschoolers understand what makes night.
Just because ancient astronomers did all of this without a telescope doesn't mean your little ones have to! All of the above activities can be done with the naked eye but if you feel like shooting for the stars check out Learning Resources Big View Telescope. How will you celebrate Astronomy Day?
