Conservation of Mass

STEM students are learning about the Conservation of Mass. We've explored questions like:
If you melt an ice cube, does it weight more as a solid or a liquid?
If you break a cookie, does it change the weight?
Can we predict the weight of lemonade if we know the weight of the water and the mix?

Today we began to look at creating new substances by mixing different substances. We started by making Super Slime. It was messy but so much fun!!
