Building Bridges

From Explore Forces and Motion!

Forces act on everything, even things that are standing still. Engineers need to understand forces when they build structures such as bridges. Let's see how different bridges support the forces that are placed upon them.

On the Straight and Level

On the Straight and Level

From Explore Gravity!

In the introduction you made a plumb bob that used gravity to make sure things are vertical. Now you can make a water level, a tool that uses gravity to make sure things are straight across! The water level works because when water is in a confined space, gravity makes sure the top of it is level.

Samuel L. Nerenberg, Doctoral Candidate of Optical Sciences
"An excellent introductory text for children to the field of optics. It provides a balance between scientific concept and history presented at an appropriate level. In addition, the included experiments are cleverly constructed and with a little extra investigation demonstrate some very fundamental aspects of the nature of light."
