This week in Science we explored the concept of porosity, and determined that paper egg cartons and unglazed pottery are very porous and let a lot of water through. Coating on the outside of those containers such as a pottery glaze changes the porosity, and we observed glazed pottery being waterproof. We are also waiting to see which of the four containers we placed around the classroom will evaporate the fastest. The class suspects that the windy location will lead to the fastest evaporation, but we’ll see on Monday! You can also watch a few of the liquid videos we’ve been watching below.
