Want your students to study and launch water bottle rockets but need guidance?
Well, I am here to help. The PowerPoint in this bundle will take your students through key vocabulary such as drag, ballast, thrust and discuss how Newton’s Three Laws affect the launch of a rocket.
Day 1, students will work through the PowerPoint individually and design a water bottle rocket. Students will then join with a partner who also has a plan and merge their ideas into one design plan that they will build.
Day 2, students will build their rockets with materials they provide. I provide scissors and rulers. They are even required to bring tape. During day 2, I fit their bottles onto the launcher so that they know it fits. I also check to make sure that bottles are not too thin (For example, small water bottles are too thin). I launch at about 60 psi, so that is not safe for small, thin water bottles. You will need to decide the psi that you launch with and if you will use a bicycle pump or a compressor. Bicycle pumps will not reach a very high psi and it takes much longer to launch a lot of students. Your choice will also affect the time rockets are in the air so you may have to adjust that “time in air” number on the rubric. Or (better plan), adjust after everyone launches and then use that number for NEXT year. :)
Day 3, it is launch day. I launch with a very high quality launcher and use an air compressor. I am including the brand that I use, but in no way endorse them. It is your decision which launcher you choose. Be careful with cheap launchers. You and your students will probably be disappointed and you will keep wasting money on cheap brands. This is the best I’ve found. https://www.pitsco.com/Aquaport_II_Water_Rocket_Launcher
