A hands-on approach introduces young scientists to springs. Science theory and practical, fun projects teach the physics and the technology behind this simple machine. Important science curriculum is explained through historical and contemporary examples of springs. Step-by-step projects range from the simple to the more challenging.

Why is a spring like a simple machine? What forces do you need for a spring to change shape? How do springs store energy? Look at everything from historical examples of springs, such as a ballista, to the role of levers in complex machines, such as racing cars.
