Readers will learn about electricity while performing the short experiments in this book.

Why did ancient Egyptians put oil on the ground while they were building the pyramids?

The oil reduced friction and allowed them to drag huge stone blocks along the ground.

Inside, you'll find:

* How forces such as inertia and friction relate to motion;

* A timeline, photos - and how humans have used the laws of motion to invent things such as roller coasters and space shuttles;

* Surprising TRUE facts that will shock and amaze you!
