How do Self-Driving Cars Know What to Do?

STEM Activity

237 reviews

How do driverless cars know what to do at an intersection? How do they know when they should stop and when it is their turn to go? What about yielding to pedestrians? In this activity, you will write your own algorithm, or list of steps, for a driverless car to follow when navigating through various road scenarios like stop signs, traffic lights, and roundabouts (traffic circles).

Make a Night-Light

STEM Activity

29 reviews

Are you ready to move beyond paper circuits and squishy circuits? This is a great intermediate circuit project where you will build your own working night-light. And of course, you will have some fun decorating it! Read more

Make Your Own Hand Sanitizer

STEM Activity

35 reviews

Did you ever wonder what hand sanitizer is made of, or how you can efficiently disinfect your hands or other frequently touched surfaces like doorknobs? Handwashing is still the best way to keep your hands clean, but hand sanitizer is a great alternative for situations where clean water and soap are not available, and you can even use it to disinfect surfaces! Intrigued—try out making a hand sanitizer yourself! Read more

Make String from Algae

STEM Activity

226 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

The Impossible Arrow Illusion

STEM Activity

33 reviews

Make your own 3D printed "impossible arrow" illusion in this fun activity. No matter how many times you spin the arrow around, it always seems to point in the same direction—but its reflection in a mirror points the other way! How does it work? Try it and find out! Read more

Apparent Motion in Flipbooks

STEM Activity

39 reviews

Have you ever been tricked by an optical illusion? Optical illusions can be fun, but they are also quite scientific. In this activity you will investigate the phenomenon of apparent motion by making your own flipbook animations. Read more

Circus-Trick Science: How to Balance Anything

STEM Activity

18 reviews

Have you ever wondered why it is harder to keep your balance with a heavy backpack on? Or why it is difficult to make a toddler's sippy cup tip over? Maybe you are the kind of person who wonders about circus balancing acts and would like to learn how to ride a bike on a rope. Or perhaps you want to know how to make your toy car less prone to toppling over when racing through a sharp curve. In this science activity, you will get to investigate balance using marshmallows, skewers, and… Read more

Homemade Rice Paper

STEM Activity

7 reviews

Have you ever encountered "paper" on your plate—perhaps in the form of thin paper for spring rolls, or cake decorating? Did it make you wonder how this paper relates to the paper you write on? You will find out in this activity! In addition, you can discover the recipe to make the edible paper you like best. Read more

Soil Science: Study Microorganisms in Winogradsky Columns

STEM Activity

10 reviews

Our planet recycles and reuses everything on it that is needed to support life. It is an amazing, giant recycling system called the biogeochemical cycle. You can actually model this on a small scale by using a plastic bottle and mud to build what is called a Winogradsky column. In this activity, you will build your own Winogradsky columns and investigate how including different nutrients can affect which soil microorganisms flourish and which fail. Read more

The Ambiguous Cylinder Illusion

STEM Activity

22 reviews

Is it a circle? Is it a square? Or is it both? Make your own 3D printed "ambiguous cylinder" illusion in this fun activity. Read more

The Bouba-Kiki Effect

STEM Activity

20 reviews

If you had to name some shapes "Bouba" and others "Kiki," which name would you give a pointy shape? How about a rounded shape? Would your friends have the same answers? In this activity, you will investigate the Bouba-Kiki effect to learn more about the human brain's fascinating connection between shapes and sounds. Read more
