What Kids Learn From This STEAM Activity
In the STEAM activity, Pepper and Water Science Experiment, you’ll discover how water molecules behave in a very cool way. When you sprinkle black pepper on water, you’ll notice the pepper flakes float on the surface. When you touch the water with a soapy finger, the pepper flakes rush to the sides of the bowl. This happens because the soap changes the water’s surface tension. It’s a bit like magic! This teaches you about how substances interact and why soap is great at cleaning things. It’s a fun way to learn about science and the properties of water and soap!
*Surface tension: Surface tension is like a “skin” on the surface of water that makes it act like a stretchy sheet. It’s why water droplets are round and bugs can walk on water.

Variations & Challenges
- Predict what will happen if you use more or less soap. Test your predictions by trying different amounts.
- Instead of water, use other liquids like milk or juice. See if the pepper behaves differently.
