Word of the Week (April 9-16)

 Our word of the week is “accelerate”. Accelerate means to go faster and faster.

This past week we made film canister rockets and watched them accelerate high above our heads. We mixed water with Alka-Seltzer tablets in small film canisters with tight-fitting lids.

A gas called carbon dioxide was produced. As more and more gas was produced, more and more PRESSURE built up inside the canisters until . . . the lids popped off and the canisters went up, up, up!!!!!!!
