Super Scientist Gavin!




Super Scientist Gavin did an excellent job teaching Mrs. W’s class how to build a film canister rocket. He used an empty film canister and filled it with a lttle water. He then added an Alka Seltzer tablet and quickly put the top on the canister. He turned the canister upside down, and boy, did it shoot up in the air like a rocket!!!! He showed us that the rocket goes up higher if you do not put at much water because there is more pressure in the canister. If you put more water in, the canister will not shoot through the air as far because there is no room for the pressure to build up. The Alka Seltzer tablet creates a chemical reaction and therefore, water pressure. What a super job, Gavin!
