A Soluble Separation Solution

STEM Activity

6 reviews

Have you ever mixed sand and salt together and wondered how you could separate them again? If you had to separate them, would you have nightmares of tiny tweezers, a magnifying glass and hours spent picking grains of salt and sand apart? Don't be afraid, there is another way! Using the differences in solubility between salt and sand, you can find the simple "solution" to this problem. Read more

Absorb the Shock!

STEM Activity

6 reviews

Have you ever ridden in a car over a pothole or a speed bump? You might feel the bumps and get tossed up and down in your seat a little bit, but not nearly as much as you would if the car did not have a suspension. Try this engineering project to learn how a suspension helps give you a smoother ride! Read more

An Infinite Number of Reflections? Really?

STEM Activity

23 reviews

Can you imagine a bouncy ball bouncing back and forth between two walls, infinitely? Wouldn’t that be amazing? What if, instead of a ball, light was bouncing between two mirror walls; would it bounce back and forth forever? Imagine each light bounce added one reflection of you in the mirror; would it look like there were an infinite number of “you’s” in there? Can we create an infinite number of reflections? Try this activity and be amazed by the many… Read more

Make String from Algae

STEM Activity

225 reviews

Did you know that the seaweed you've seen in the ocean or even eaten as a snack is inspiring innovators to imagine new materials? Large brown algae, like kelp, contains polymers—long chains of molecules—that are more environmentally friendly than the ones in most plastics. These natural polymers (alginates) could eventually be used to create sustainable everyday objects. Try your hand at using a bit of chemistry to turn biodegradable polymers from algae into your own custom… Read more

Automatic Drone Balancing

STEM Activity

10 reviews

How do drones automatically balance themselves when you let go of the controls? Find out in this project as you build and program an experimental setup to make a drone automatically control its tilt angle about a single axis. See this page for a complete list of our mini drone projects. You may wish to do the projects in order. Read more

Baking Soda Weight Loss

STEM Activity

1 review

Baking soda is not only great for cooking; it is also a useful chemical for science projects. You have probably heard about and maybe even used the baking soda/vinegar reaction to make volcanos erupt, shoot bottle rockets up in the air, or to detect acids and bases. However, there are many more chemical reactions that you can explore with the help of baking soda. One of them is called a decomposition reaction, which makes baking soda lose weight! Want to find out how it works? Then try this… Read more

Balancing Act

STEM Activity

18 reviews

What makes an object balanced? Look around you—most of the objects in the room are probably balanced and not on the verge of tipping over. If someone hands you an object and asks you to put it down, you probably know, without thinking about it too much, how to place it so it won't fall over. But what's the science behind how an object balances? Why do certain objects only balance on some sides and not others? Try this project to find out! Read more

Be Seen In the Dark

STEM Activity

Being outside in the evening can be relaxing as well as exciting and fun, but it could also be dangerous. Did you know that in 2014, on average, 13 pedestrians died on American roads every day and three out of every four pedestrian fatalities happened in poor light conditions, such as dusk, dawn, or at night? When considering these worrisome numbers, do you think the types of clothes worn could make a difference in how visible pedestrians are to drivers? If so, what should you wear: bright… Read more

Best Wand for Big Bubbles

STEM Activity

5 reviews

Have you ever tried to blow a bubble, and no matter how hard you try, the bubble just will not form? Why does this happen? Why do bubbles form at all, and why is it harder to blow bubbles sometimes? In this activity, we will explore the limits of how big our bubbles can get! Read more

Bird-Spotting Science: Predicting a Bird's Lifestyle Based on its Feet

STEM Activity

6 reviews

Have you ever wondered how animals can survive in all sorts of extreme environments, from a polar bear that’s out and about when it’s -40°F and a desert iguana finding food as the temperature rises to 110°F, to a deep sea anglerfish living thousands of feet down in the sea? How do they do it? The answer is adaptations! Their bodies have special features that allow them to live in those environments. In this activity, you’ll investigate what the… Read more

Build a Differential from K'Nex®

STEM Activity

10 reviews

What in the world is a differential and what does it do? A differential is a mechanism that helps cars go around turns without the wheels slipping. In this activity you will build your own working model differential from a building toy like K'Nex®! Read more
