I'm guessing you have made a paper airplane at some point in your life, or at least seen someone else make one, but have you ever made a paper rocket? This is a simple model, but it's a great opportunity to practice data collection and test your understanding of aerodynamics. Use the instructions provided in the "Make a Rocket" link below to learn how to make a paper rocket that can be launched with a straw. If you can, find someone to make a paper rocket with you. Once you have your rockets, collect data on how long they stay in the air and how far they go. Analyze your data and redesign your rocket so that it flies longer and farther! What happens if you make the rocket longer? shorter? What if you change the number or size of the fins? Does the type of paper matter? Build more paper rockets and compare them to answer these questions.
If you have a hard time following the instructions, watch the videos below to see how to make a paper rocket.
Added Challenge:
If you want to challenge yourself, see if you can identify and explain the four forces acting on your paper rocket. Spend some time researching aerodynamics and how engineers use these concepts when the design and build real planes and rockets.
