STEAM Projects You Can Do Today

Make Instant Ice

Water is usually loaded with particles and impurities, which enables ice to form. But purified water isn’t. This allows purified water to reach way colder temperature before solidifying.

If you leave an unopened bottle of purified water in the freezer for two to three hours, the bottle will be way colder than the freezing point of regular water. When you pour that super-chilled water onto a block of ice, it latches onto the ice’s impurities and freezes instantly!

Self Watering Planter

Learn how to water your plants with just string and a Ziplock bag! In this project, you’ll run a string from the bag of water directly into the soil, where the plant roots will soak up the water. You’ll need to use a low container to make sure the bag rests gently on the ground. Then your plants will have a steady supply of water to keep them green and growing!

Rubber Band Helicopter

Learn about helicopters by making a rubber band powered flying toy! The two propellers on your rubber band helicopter are able to fly thanks to the same principles that keep real helicopters aloft. The angled blades of the propellers act like fans when they spin, pulling air from above and blowing the air downwards. This creates enough lift to counter the effect of gravity on the helicopter, pushing it higher and higher into the sky!

Egg Drop Project

When an egg drops from a second-story window, it picks up 32 feet/second of speed for every second it falls. By the time the egg reaches the ground, it’s going at about 24 miles per hour. And then, suddenly, its speed drops to 0 miles per hour (usually along with a big SPLAT). How can you get an egg to drop without breaking it? Change the way it drops with this awesome egg drop experiment!

Cranberry Chemistry

What do cranberries and chameleons have in common? They can both change color! Cranberries contain chemicals called anthocyanins, which change color depending on how acidic their surroundings are. (They are natural pH indicators!) Since cranberries are naturally acidic, they normally look red, but we can neutralize the acid to find the berry’s true colors.
