Have you ever woken up on a cold, frosty morning and just wanted to snuggle down deeper under the covers? Animals, like puppies and piglets, do not like being cold either, but they do not have hands or blankets to wrap themselves up. So when animals get chilled, they change their behavior and do things like huddle – they curl up close to other animals. In this science activity, you’ll see just how much huddling can help reduce heat loss. Read more

Soft-Boiled Science: Egg-cellently Cooked Eggs

STEM Activity

Make String from Algae

STEM Activity

215 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

Soil Compaction

STEM Activity

2 reviews

Have you ever noticed how much work it is to dig a hole in really hard soil? It's much easier to dig a hole in soft, loose soil. But why is that? Soil that is hard and dry is often compacted, which means that it has been packed down, making it denser and thereby difficult to penetrate. Soil that has become compacted is not only harder for you to dig a hole in, but it can also be much harder for a lot of other organisms, such as helpful earthworms, to survive in. Read more

Soil Science: How Moist is that Mud?

STEM Activity

Have you ever taken a step onto what appeared to be dry ground, only to find yourself ankle-deep in mud? Yuck! When you walk through damp soil, it can be a very messy experience. How can you tell if soil is wet or dry before you step on it? In this science activity, you will investigate whether the color of the soil can help you determine how dry or wet it is. Read more

Solidifying Science: Which Fruits Can Ruin Your Gelatin Dessert?

STEM Activity

Have you ever noticed that if you’re making a gelatin dessert, like JELL-O, it’s not recommended to use certain fruits, like pineapple? Why is this? It’s because these fruits may prevent the gelatin from solidifying. In this activity you’ll get to determine if certain enzymes in some fruits are preventing the gelatin from solidifying, and whether there’s a way to still include these fruits without ruining your gelatin dessert!

Soupy Science: Investigate How Dried Beans Absorb Water

STEM Activity

1 review

Have you ever had black-eyed peas for New Year’s Day? They’re often used as part of a traditional meal in the South on this day. Dried beans themselves are a major ingredient in dishes served all over the world. In their dried form, they can be stored for years and then “brought back to life” by soaking them in water. In this science activity, you will explore how the temperature of the water used to rehydrate dried black-eyed peas (which are technically beans) affects… Read more

Speedy Science: How Does Constant Acceleration Affect Distances Traveled?

STEM Activity

23 reviews

Have you ever dropped something and wondered how fast it was moving while falling? If it was something fragile, like a cell phone, you might not have been thinking about this at the time – you were likely too busy trying to grab the phone! But you probably wanted to find out how hard it hit the ground afterwards. We all know that gravity forces an object to fall, but how does this affect how quickly something falls and its impact? For example, did the phone move faster right after leaving… Read more

Spooky Science: The Sounds of Halloween
