Construction and science are all around us. Big and noisy construction equipment grabs kid's attention. This Discovery Library series will too while explaining basic physics. Simple machines, balance, friction, sound, and other basic concepts are demonstrated in a construction zone. The images help kids relate simple science concepts to the real world.

Titles in this series include:
* Good Friction, Bad Friction - identifies observable forces in nature
* Loud Sounds, Soft Sounds - identifies the difference between sounds
* Moving Machines - identifies examples of motion
* Pushes and Pulls - identifies observable forces in nature
* Things That Balance - explores the position and motion of objects
