Week 3: October 27th, 2010

This week the 3rd and 4th grade science club joined forces to build home-made rockets!  After learning the basics of rocket building, we spent the rest of the session outdoors competing to see which team's rocket would launch the highest.  Our rockets were made by filling a film canister with an Alka-Seltzer tablet and water. The chemical reaction from the Alka-Seltzer mixing with water created a pressure build-up within the film canister.  Once enough pressure had built up, the canister was launched in the air! The girls did a great job determining the optimum combination of water and Alka-Seltzer for the highest rocket launch.
