3 States of Matter

Today we have been studying about the three states of matter: solids, liquids, and gases. We did several experiments. The experiments were from the book "Solids, liquids, and gases" by Louise Osborne.

We mixed a solid, baking soda, with a liquid, vinegar, to create a gas, carbon dioxide. The gas filled up the balloon.















We also used salt, a solid, to melt ice, another solid. The ice then froze again and stuck to the piece of yarn. Alex was able to pull the icecube out of the water with the yarn!
