A Fun Introduction to a Basic Concept of Physics - Screws! Focusing on simple machines and how they help us do work in our daily lives, this fun and informative new series introduces young readers to several basic concepts of physics. We've all seen screws, but how do they work? Why is it easier to screw something into something than to simply push it in? With basic hands-on experiments and clear descriptions, this simple machine is explained.

The Way Things Work - Screws

In Screws, inhabitants of Mammoth Island are in the process of building a new observation tower out of stone blocks when one of the islanders gets trapped at the top of the tower. With the help of a visiting gallant knight and his trusty mammoth, they are able to build a ramp around the circular structure and create a giant simple machine known as a screw. Turning the tower into a giant screw allows the islanders to spin the tower down into the soil, bringing the trapped inhabitant of Mammoth Island close to the ground -- and saving the day!
