Model Your Blood Flow

STEM Activity

66 reviews

Why is it important to eat healthy and exercise? If you don't, you might end up with a cardiovascular disease. These diseases are conditions that affect your heart and blood vessels. The job of your cardiovascular system is to transport blood through your heart, veins, and arteries, to provide oxygen and nutrients to your body. If this blood flow doesn't work properly anymore, it can have serious consequences. In this activity, you will find out what happens to the blood flow of people that… Read more

Solubility Science: How Much is Too Much?

STEM Activity

51 reviews

Have you ever added a spoon of sugar to your tea and wondered why it disappeared? Where did it go? The sugar did not actually disappear—it changed from its solid form into a dissolved form in a process called chemical dissolution. The result is a tea-sugar mixture in which individual sugar molecules become uniformly distributed in the tea. But what happens if you increase the amount of sugar that you add to your tea? Does it still dissolve? In this science activity, you will find out how… Read more

Suck It Up! How Water Moves Through Plants

STEM Activity

116 reviews

Have you ever heard someone say, "That plant is thirsty," or, "Give that plant a drink of water"? We know that all plants need water to survive, even bouquets of cut flowers and plants living in deserts. But have you ever thought about how the water moves within the plant? In this activity, you will put carnations in dyed water to figure out where the water goes. Where do you think the dyed water will travel, and what will this tell you about how the water moves in the cut flowers? Read more

Make String from Algae

STEM Activity

222 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

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

45 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

Build a Cooler

STEM Activity

135 reviews

How does a cooler keep things cold? Which material makes the best insulation? Try this project to find out how long you can keep an ice cube from melting once it's out of the freezer! Read more

Build a Gumdrop Geodesic Dome

STEM Activity

91 reviews

Have you ever seen a geodesic dome? Geodesic domes are approximately sphere-like structures made up of interconnected triangles. A famous geodesic dome is Spaceship Earth at EPCOT in Walt Disney World, Florida, but geodesic domes are also commonly found as climbing domes at playgrounds. In this science activity, you will get to build a simple geodesic dome using gumdrops and toothpicks. Once it is built, you may be surprised by how strong it is! Get ready to do some tasty engineering! Read more

Build a Marble Roller Coaster

STEM Activity

71 reviews

How much energy does a roller coaster need to go through a loop without getting stuck? Build your own marble roller coaster in this project and find out! Read more

Candy Rainbow

STEM Activity

108 reviews

Here is a fun project you can try with leftover candy you have. You will make some amazing art using nothing but colored candy and hot water—and a little bit of science. Save some of your candy and get started! Read more

Flying Helicopters on Mars

STEM Activity

70 reviews

During the Mars 2020 mission, NASA plans to explore the surface of Mars using a rover in combination with a lightweight helicopter. To be able to fly on Mars, this helicopter must be super light and have very efficient blades. If not, it will never generate enough lift to get off the ground. In this activity, you will make your own paper helicopter and test different blade designs. Will your findings be reflected in NASA's design? Try it out and see for yourself! Read more
