This is harder than it looks!
- The final investigation of our Water unit focused on how water works for us. We looked at a picture of a mill and discussed how the waterwheel created energy. We learned that water helps us move things, lift things, and make energy. The challenge that the children had was to work with their tablemates to create a waterwheel using 5 discs, 3 clips, a meter length of string, a dowel, and a basin. Once one table got the idea, everyone was successful. When the waterwheel was together, they had to use a 50 ml syringe to squirt water onto the wheel which lifted a heavy clip. It was interesting watching the children work with one another and how funny some of the ideas were. We had fun and got a little wet!
Table 1 does a great job getting their waterwheel together.

Mrs. D. teaches us about the sources of pollution in our water.

We had a wonderful visit today from the Whitney Waterworks in Hamden in conjunction with our science unit on WATER. The focus was on water pollution. The children were introduced to the term “point source” and “non-point source” of pollution. Point source pollution is when you know where the pollution is coming from and can stop it. Non-point source is when pollution comes from multiple sources and it’s difficult to stop. Ask your children what happened to “Freddie the Fish”. They brought home a diagram that was used to illustrate sources of pollution and also a drawing showing pollution or not. Thanks to John Ruggiero for his tip to help Mrs. M. get rid of her many cans of latex paint. If you add kitty litter to the can, it will absorb the paint and then the garbage company will take it! Bravo John.
