This fun activity will teach you a little bit about rockets. It is from one of NASA‘s educational websites and the great rocket template you’ll find below is provided by the Jet Propulsion Laboratory at the California Institute of Technology.
All you’ll need is a plastic soda straw, some paper, scissors and tape. For the body of your rocket, you can use this template or simply cut a strip of paper an inch or two wide. If using the template, wrap the rectangle of paper around a pencil and tape it into a tube. If you’re using a strip of paper, wind it around a pencil (as pictured above) so it forms a tube. Tape it well, so it holds its shape.
Now, remove your rocket from the pencil, fold one end over and tape it down. This will be the nose of your rocket. To the other end, you can make fins using the template, or design your own fins to tape on. Fins work best at right angles, or near right angles. Now you can decorate your creation.
Put your rocket over the end of a straw and use the force of your breath to launch it! How far does it go? Try making longer and shorter rockets. What happens if you change the shape or number of fins? Record your flight lengths.
What does this teach you? Paper rockets demonstrate how real rockets fly through the atmosphere and some of the forces working on them!
Drag is the force of air getting in the way of your rocket. Weight also drags your rocket down as gravity pulls on it. The lighter you make your rocket (less paper, less tape), and the less drag it has, the farther it will go!
Fins stabilize the rockets’ flight. The size and design of the fins affect how well it can be controlled.
This summer, get off screens and get outside with this fun project from my book Kitchen Science Lab for Kids!
