Source Institutions
In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.
Gas Production: Blow up a balloon!
Source Institutions
In this classic reaction, learners baking soda and vinegar in a soda bottle to produce carbon dioxide (CO2) gas. This gas inflates a balloon.
Soda Explosion
Source Institutions
This hands-on activity lets participant explore chemical reactions as they create a soda explosion with lots of bubbles. The bubbles in soda are made of carbon dioxide gas.
Electric Paddle Boat
Source Institutions
In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.
The Straw Flute
Source Institutions
In this is activity about sound and vibration, learners create their own 'flutes' with drinking straws, then investigate how changing the length of the straw affects the sounds that are produced.
Make Your Own Slushies
Source Institutions
In this activity, learners will make their own slushies and learn some of the science behind how the process works.
Make Maracas
Source Institutions
Make a rattle-like musical instrument! Shake it, hit it, spin it any way you want to!
Reflecting Rainbows: Decorate Your White Walls With Rainbow Colors!
Source Institutions
Like water drops in falling rain, a CD separates white light into all the colors that make it up.
