For science, one week we learned about sound and vibrations. We made cup telephones as part of this, and I guess this is a photo of that, but really it's of the cute Barrys with their crazy hair!
And the other week we learned about the different kinds of energy, but mostly kinetic and potential energy. As part of this, we had film canisters (I feel so old that no one knows what film canisters are anymore!) and filled them with denture cleaners (which work like alka seltzer tablets by fizzing in water) and they blew up like rockets and they LOVED that.
