Build a Bird Nest

STEM Activity

68 reviews

Different types of birds lay their eggs in different places. Some build tiny nests in bushes, some build enormous nests in tall trees. Some lay their eggs directly on the ground or on rocky ledges. Those that build nests use many different types of materials. In this project you will try to build your own bird nest using only natural materials that you can find outside. Can you do better than a bird? Read more

Investigate Alien Genetics

STEM Activity

123 reviews

Have you ever wondered why biological siblings look so much alike? Why do they often share physical traits, such as hair color or eye color? It all has to do with their genes. Genes are passed on from parents to their offspring. This means that you share some of the same genes with your biological parents and siblings! In this activity, you will use an alien model to demonstrate how genes or physical traits are passed on from parents to their offspring. How similar will your alien siblings look? Read more

Make String from Algae

STEM Activity

213 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

Build a Brushbot

STEM Activity

122 reviews

Brushbots are a simple, fun type of robot that you can build out of arts and crafts materials. They are easy to build and you do not need any previous experience with robotics. You can build them yourself, build two robots with a friend and race them against each other, or even make them sumo wrestle! Go to the Materials section to see what parts you need to build a brushbot, and see the instructions for a step-by-step guide on how to build one. Read more

Build an Archimedes Screw

STEM Activity

79 reviews

The Archimedes screw is an ancient device used to lift water from one location to another. They are so useful that they are still in widespread use today! After a quick trip to the hardware store, you can build your own Archimedes screw in this fun activity. Read more

Hydroponics Made Easy

STEM Activity

137 reviews

Do you think plants can grow without soil? If you've tried growing vegetables, you probably planted the seeds or seedlings in soil. Soil gives the plants the nutrients they need to grow. However, plants can grow without soil, too, using a process called hydroponics. In this activity, you will transform a bottle into a mini-garden that needs only light, air, and nutrient-rich water to grow! Read more

Make Your Own Stethoscope

STEM Activity

118 reviews

Have you ever wondered what happens to the heart as we exercise intensely? How does its beating change? A doctor can figure this out by using a tool called a stethoscope, which is a long, thin plastic tube that has a small disc on one end and earpieces on the other end. In this activity, you will make a homemade stethoscope and use it to measure peoples' heart rates at rest and after exercising. Read more

Test Your Foods for Starch

STEM Activity

61 reviews

Have you ever heard about starchy and non-starchy foods? What is the difference? Starchy foods contain the carbohydrate starch, which is converted to sugar (glucose) inside our body for energy production. How do we know which foods contain starch and which do not? There is a simple chemical test that you can do to detect starch, which involves an iodine solution. The iodine solution turns any food that contains starch dark blue. Try this activity and watch it in action yourself! Read more

Are You Left or Right Brained?

STEM Activity

164 reviews

If you write with your right hand, you may also prefer to draw, throw a ball, or eat food with your right hand, but have you ever wondered if your right foot is also more dominant than your left foot? What about your right eye and ear — do you prefer to use them more than your left ones? In this activity, you will get to find out whether people have a sidedness — that is, whether they generally prefer to do activities with one side of their body — and what that might say… Read more

Blowing the Best Bubbles

STEM Activity

41 reviews

If you have ever tried to make bubbles using plain water, you may have seen that it does not work. This is because the surface tension of water is too high. When detergent is added to water, it lowers the surface tension so that bubbles can form. Other things can be added to this mixture, such as corn syrup or glycerin, to make a solution that is even better for creating bubbles. In this science activity, you will find out which solution creates the best bubbles! Read more
