Honors Chemistry Name: ________________________________________________ Mods: ________________ Gas Laws: Film Canister Rockets (25 pts) Objective: To construct a rocket propelled by Alka-Seltzer and water that demonstrates the role of chemical reactions and gas laws. Procedures: Prepare and decorate a rocket using a film canister and the seltzer rocket template. Hold the rocket upside down and add water to make the canister approximately ¼ full. Take the rocket outside or to designated pad”. “launch Add half a tablet of Alka-Seltzer® to the film canister and quickly snap on the lid. Place the rocket on the ground, lid side down. Stand back and count down while you are waiting for launch! Follow-up Questions: Explain the chemistry behind the film canister rocket. In other words, why did the rockets “lift off”? This may require looking up the chemistry of Alka-Seltzer. What two gas laws best describe the chemical phenomenon observed in this activity? What variables could be changed in order to increase the height/distance the rocket travelled?
