Find the North Star, and measure your latitude! The purpose of this science fair project is to find latitude and learn about geographic locations.

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

Design and build an invention inspired by Rube Goldberg's designs. Build your invention. Test the machine, write a detailed report.

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

Develop a new system for predicting geographic changes. Demonstrate the nature of geographic change. Make logical predictions.

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.

Investigate the advantages of the use of ceramics in engines such as the tiles used in Space Shuttle. Use iron filings and magnets.

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.

This project explores the interaction between air pressure and playing surface in determining a basketballâs bounce.

Determine which seeds are most likely to survive harsh winter conditions (low temperatures).

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 examines whether ocean water can be made safe to drink.

This experiment investigates whether left-handed test subjects have better memories than right-handed participants.

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

Science fair project that builds a magnetometer and demonstrate its uses.

Science fair project that measure winds speed, temperature, and time of day in order to determine the origins of the wind.

Learn about the role of Earth's rotation on the Coriolis Effect and hurricanes in this science project. Model the Coriolis Effect on a hurricane's direction.

Do you hate to waste energy? In this experiment, you will design a machine that is powered by the process known as energy transformation.

This science fair project idea designs safe bicycle routes using GPS.

Free science fair project idea that examines the impact of gravity on a dropped carton of eggs. Design a device to protect the eggs from cracking.

This project is a vivid, concrete introduction to the basic but important idea that plants need sunlight and water to grow.

Study the effects of wind and temperature on evaporation. Place wet sponges in different environments, check at regular intervals, track time required to dry.

Science fair project that determines how UV radiation emitted by the sun varies depending on the time of day, using a handheld UV detector

In this science fair project, students determine whether a bean plant grows faster and taller using a traditional soil planting method or hydroponic method.

This project determines the age of a tree using a growth factor chart instead of cutting the tree down to count the rings in its base.
