Students learn how and why engineers design satellites to benefit life on Earth, as well as explore motion, rockets and rocket motion. Through six lessons and 10 associated hands-on activities, students discover that the motion of all objects—everything from the flight of a rocket to the movement of a canoe—is governed by Newton's three laws of motion. This unit introduces students to the challenges of getting into space for the purpose of exploration.
How are rockets and satellites connected? How are rockets and engineers connected? How about rockets and Newton's laws? The answers are many! Engineers have played a key role in designing satellites, getting them into orbit (via rockets!), and using the data they relay back to Earth for useful purposes. Anytime engineers work on something that moves, including rockets, they use Newton's laws of motion to help describe, understand and design how it is going to move. Designing and building rockets requires many different types of engineers working together to create equipment that functions as intended. When designing rockets, engineers must not only consider how far and fast they need to go, but also their cost, safety, weight and impact on the environment. Doing this requires many, many design iterations along the way. This means engineering teams design and test a rocket, discover what is not working or could be better, and then redesign and test until a successful final design is achieved.
