Rocket science is the use of rocket propulsion to move everything from fireworks to manned space craft. At the heart of rocketry is Isaac Newton’s Third Law of Motion, which has been established for over 300 years. If you stand in front of a wall and push hard on it, it will move backwards.
Similarly, if you stand on a skateboard and throw a heavy object as hard as you can (don’t try this at home), it will roll in the opposite direction. If you push an object forward, it will push back with the same force.
In the case of a rocket, the “object” being pushed is the end product of fuel combustion, and as the fuel burns, its pews out the rear of the rocket, forcing the rocket to move in the opposite direction.
About the Book
The theme of this book is that rocketry can be used to teach physical science from any level. The subject has a continuum les that can lead students into a technical profession, like a pipe line course from K through 12. Students begin their orientation to motion and velocity by launching air straw rockets and pump-up water bottle rockets.
They then learn about force and ac celebration through demonstrations with model rockets. By middle school students, they are able to apply their understanding in design contests, and by high school students, they are able to conduct pay load experiments on larger models.
Model rockets are fully representative of the scientific process and the engineering application of real-world challenges. The study of rocketry in high school can continue at the college level until students are out of the pipe line to the job market. This guide book provides an introduction to the flow of model rocket science activities that support the pipeline.
The study of motion is one of the foundations of physics that students must learn. The dynamic properties of an object are given by its altitude, velocity, and acceleration. From these properties come the concepts of measurement and rate of change, which are the foundation of the physical sciences. Rocketry demonstrates these concepts in a way that students at many grade levels can understand and remember.
