This week in both science classes we were exploring the physical properties of matter. To go along with that we had a "lab" in which students created Oobleck. If you are unfamiliar with Oobleck, read here. This is a really fun way for students to get engaged...and get their hands dirty.
The funny thing about this substance is that at times it acts like a solid, and others it acts like a liquid. Students also spent time thinking/discussing what other substances might also have similar properties. Needless to say they had a lot of fun.
