Last week we began our last science unit exploring states of matter. We began by sorting several jars into solids and liquids and then noticing things that were true of all the liquids and all of the solids. We noticed that liquids take the shape of the container they are in and have a flat surface in the container, while solids will hold onto their shape. From there we have been exploring liquids and water. We began by experimenting with drops of water on plastic plates and today children had a chance to explore drops of water on different surfaces: paper towel, construction paper, waxed paper, and tin foil. Some things we noticed were the drops stay really round on the wax paper, they spread out on the tinfoil, and they soak into the paper towel and construction paper. It is easy to move drops on the wax paper because they are so round and don't soak in at all.
