Study the life cycle of the common blowfly as it relates to forensic investigation. Record the first time you see flies, maggots, and eggs.

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.

This science fair project uses paper chromatography to investigate whether black, brown, orange, and purple are pure colors or mixtures of other colors.

Science fair project that uses muriatic acid to develop fingerprints that would otherwise be invisible.

Science fair project that develops latent fingerprints on a non-porous objects by converting superglue from a solid state to a gaseous state.

You've heard all about oil spills, but can they really be that bad? After all, vegetable oil is in almost every yummy baking good from cookies to brownies.

This science fair project idea compares biodiversity between drops of water.

This science fair project idea investigates how a bottom keel helps keep a boat from rocking back and forth.

This science fair project examines how tsunamis travel by simulating a tsunami moving around an island. You will generate a pretend tsunami in a swimming pool.

Every time a sound is produced it emits a sound wave. This experiment demonstrates how sound travels, using nothing more than a spoon and a string!

What heats up fasterâwater or soil? 5th grade students test the specific heat of water against the specific heat of sand in this great science fair project.

Using an empty tennis ball can and a swimming pool, you will determine if it's possible to have a conversation under water.

Brine shrimp usually live in saltwater. Investigate how salt concentration (salinity) affects the rate at which brine shrimp eggs hatch.

In this free science fair project, learn how to separate salt from water using heat. A great science project for elementary school kids.

Science fair project which measures whether tsunamis are more destructive when they are caused by an earthquake or by a meteor.

In this science experiment, observe convection currents forming and learn about how heat energy moves in liquids from hot to cooler areas through convection.

The objective of this science fair project is to analyze the effects of salinity and temperature on water.

Science fair project which determines if plants really do need water to grow, or whether they just need to be kept wet.
