Cardiovascular System Science: Investigating Heart Rate Recovery Time Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 1 review As Valentine’s Day approaches, we’re increasingly confronted with stylized images of the heart. Real hearts serve very important functions – a person’s heart beats to supply blood to their entire body, and the heart has to work harder when they exercise. Have you ever wondered how quickly your heart beats when you exercise, or how long it takes to recover back to its normal rate after you’re done exercising? In this science activity, you’ll get to do some… Read more
Scrumptious Science: Great Globs of Gluten! Log in to add favorite More Menu
STEM Activity Do you have a favorite Thanksgiving dinner dish? Maybe it’s an aunt’s special cranberry sauce, or mashed potatoes combined with perfectly-seasoned gravy. Or perhaps you enjoy sinking your teeth into a succulent roasted turkey the most. Dinner rolls, biscuits, corn breads, muffins, pastries and pies may also be baked for this special meal; the foods in this group typically all contain a substance called gluten. In this science activity, you’ll explore why some foods, all made… Read more
Make Cardboard Automata Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 37 reviews Have you ever wondered how to create art with moving parts using nothing but cardboard, a few skewers, and some craft supplies? In this fun STEM activity, you will build an automaton, a machine that makes parts appear and disappear, move up and down, spin in circles, or all of these together. The instructions will show you how to build a moving caterpillar, but you can use your imagination to build any other animal or object you want! Read more
Featured Make String from Algae Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 47 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 Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 6 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
Build a Bristlebot, a Tiny Toothbrush Robot Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 85 reviews Do you think you could build a robot on the head of a toothbrush? Bristlebots are simple, tiny robots that buzz around like bugs. They are easy to build and fun to play with, and you do not need any previous experience with robotics to make one. You can even build two bristlebots and race them against each other! Move on to the Materials section to see what parts you need to build bristlebots, and the instructions for step-by-step directions on how to build them. Read more
Are You Left or Right Brained? Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 128 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
Build Your Own Sports Equipment Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 17 reviews Do you play or watch a sport where you use something (other than your hands or feet) to hit a ball? Golf, baseball, tennis, hockey—there are many different sports where players use something to hit a ball or a puck. In this activity you will design, build, and test your own sports equipment made from recycled materials. Read more
Oobleck: A Recipe for a Mesmerizing Mixture Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 58 reviews Have you ever wondered what whipped cream, jelly, and milk have in common? Aside from all being tasty, they are also all made up of tiny particles that are dispersed, or distributed, in water. This type of mixture is called a heterogeneous mixture. Some of these have very interesting physical properties, such as acting like a solid and a liquid at the same time! In this activity, you will get to create Oobleck, a mixture that is made using cornstarch and water, and then explore these… Read more
How Much Weight Can Aluminum Foil Boats Float? Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 124 reviews Have you ever wondered how a ship made of steel can float? If you drop a steel bolt in a bucket of water, the bolt quickly sinks to the bottom. Then how can a steel ship float? And better yet, how can a steel ship carry a heavy load without sinking? It has to do with the density, or the mass per volume, of the ship (and its cargo) compared to the density of water. In this science activity, you will make little "boats" out of aluminum foil to explore how their size affects how much weight… Read more
Underwater Color Bursts Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 46 reviews Summertime often brings beautiful fireworks displays. Whereas you normally look up into the sky to see fireworks, in this activity we will take the bursts of color underwater—with chemistry. Although it is not exactly the same as real fireworks, you will be amazed by the color explosions you will see. Curious about what that looks like? See for yourself in this activity! Read more
