What's going on inside of that balloon?

This week, we are observing something that’s around us every day, even though we don’t always notice it. When the wind blows the leaves on the ground, soda bubbles tickle your throat, or helium balloons float away into the sky, we are experiencing gas matter. Scientists were able to experiment with gases in many ways including hearing, feeling, and seeing this seemingly mysterious and invisible matter. Students designed their own “gas matter rocket”, also known as a strawket.

At home, use gas matter from your lungs to fly your rocket through the air as far as it can go!

Why does my cereal get soggy?

Students encounter liquids everyday, but a lot of times it seems that the liquid just disappears: milk absorbs into cereal, and water from a bath absorbs into a towel. Where does the liquid go? We tested some materials that have the ability to absorb liquids by trapping it inside of pores or small holes. We also observed that not all materials are able to absorb the same amount of liquid. Different materials have different saturation points. For example, a mop can soak up a big spill, but your favorite cereal gets soggy really fast. Today, kids created a tool with absorbent materials to soak up those liquids. At home, ask your kid what else they can absorb with their new absorption tool!
