This science fair project idea develops an understanding through experimentation of which shapes are the most structurally strong.

Glass is see-through, but usually you can still see that it is there. In this experiment, we use baby oil to make glass go completely invisible.

This science fair project idea explores whether a plastic slinky works as well as a metal slinky when walking it down the stairs.

This science fair project demonstrates the magic of arches by challenging students to stack telephone books on top of eggs without breaking them.

In this science fair project, apply the principles of leverage and force by building six simple machines designed to set weights in motion.

In this windmill model science project, you will build a windmill to learn about wheel-and-axle machines and how these simple machines are used to do work.
