This science fair project idea creates a sedimentary rock and to investigate what takes place during the rock cycle.

In this science fair project, you'll make a "ghost" appear in a test tube, and learn about what happens when hot water and cold water interact.

In this project students experiment with making music using only glasses of water.

Sink or swim? Calculate the density of various fruits and vegetables using water and a kitchen scale.

Science fair project that determines whether landscaping fabric impacts the ability of plants to receive water.

This science experiment tests whether warm or cold water works best in making cut flowers last longer.

This science fair project idea investigates which objects float and sink in honey, water, and oil.

In this experiment you explore how tectonic plates move to create land and expand bodies of water.

Science fair project that examines the behavior of water and gravel in creek beds and the formation of sedimentary rocks.

This science fair project idea explores whether boiling and freezing water will have an effect on how much it weighs.

Examine which metal conducts more heat by boiling water in 3 pans made of aluminum, copper, and stainless steel.

This science fair project idea studies which kind of rock (sedimentary, igneous, or metamorphic) is most damaged by frozen water.

Discover whether different amounts of water added into a wine glass will produce a different pitch when their fingers are rubbed along the rim.

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.

Make water and clay play a little more scientific with this hands-on experiment that teaches displacement and shows how an object's shape affects its buoyancy.

The objective of this science fair project idea is to determine if sound travels best through the air, water or a solid.

This science fair project focuses on a polymer called hydrogel super absorbent crystal which absorbs water, swelling to many times its original size.

How does rust form? Kids will learn about the roles oxygen, water, and electrons play in rust chemistry in this cool science fair project idea.

This fun science project helps to investigate how much water can a plant take up and release in a certain period of time through the process of transpiration.

Check out this cool science project idea to learn about rocks and explore the cycles of formation, breakdown, and reformation of rocks in the Earth's crust.

Discover which fabrics shrink the most in the wash and why.

Kids will conduct a cool limewater carbon dioxide test that can be performed with common household materials to learn about the chemistry of this common gas.

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

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

What is condensation? Little mad scientists will learn about condensation, states of matter, and air pressure by conducting this cool science experiment.

In this simple science project, learn about what causes dew and what affects dew formation with a drinking glass, ice, and a soda bottle.

In this experiment, students find out what happens when a less-dense fluid interacts with a denser one, replicating the effect of cooler solid rock on magma.
