This week kids continued to experiment with water. According to this weeks' groups, water feels "soft" "smooth" and "rubbery"; smells "cold" "like my water bottle" "like a sprinkler"; tastes "like nothing" "like a pool" "like the ocean except not salty". 

Our experiments with things that sink and float continue to be both obvious- rocks sink, and unexpected - a large piece of wood, a heavy ball of wax both sink while lighter things like small plastic figurines and seashells sink. We tried to make a rule like "heavy things sink and light things float" but we found this was not always correct. We also came up with a test: when things seem to float at first we need to test to be absolutely sure that they really float by pushing them down to the bottom of our bin and seeing if they come back up. 

After looking at an aerial map of Brooklyn, kids had lots of thoughts and questions about our waterways particularly the Gowanus Canal. We discussed what pollution is, how water gets dirty and how important it is to keep it clean. 

Also this week Purple Room groups got to enjoy tasty garden snacks and harvest some bowlfuls of snap peas and cherries to share with the rest of the class. Surprisingly, it's hard to say which was sweeter!
