Science fair project which compares the rate of temperature change and the maximum temperature as a result of the angle of light radiation.

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

This project leads to an understanding that a whole may be built of smaller parts that fit and work together and provides an introduction to basic tools.

Science fair project which simulates the global conveyor belts on a small scale, and observes the effects of wind, density and temperature on water movement.

Science fair project that examines how temperature affects density and how density in turn affects the behavior of helium gas.

This project uses science and art to help students learn and teach others about Earth's endangered and extinct species.

The goal of this evaporation experiment is to learn about how different external conditions affect drying time.

This project explores whether plants can live and grow when "watered" with juice, soda, or milk.

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.
