The objective of this science project is to examine the factors that affect the dispersion of oil in water, including water agitation.

This science fair project idea creates an underwater habitat and explores the basic needs of living things under water.

This science fair project idea determines whether land or water warms more quickly and investigates how solar radiation increases the temperature of surfaces.

Blend science and math to explore a very important first grade social studies question: does our planet contain more land or more water?

In this science fair project idea, kids make water dance on the surface of a hot pan with the Leidenfrost Effect.

Science fair project that creates fog using bottles of hot and cold water.

This project examines the concentration of dissolved oxygen in water, with and without oil.

Will your liquid weigh less once you remove the fat from it? Find out in this science fair project idea.

This science fair project explores how salt and sugar affect the melting rate of ice in water.

Explore properties of liquids and how temperature and salinity effect surface tension of liquids in this fun- filled science fair project idea.

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

Science fair project that tests how heat affects the chemical reaction between a seltzer tablet and a glass of water.

Kids discover what a homogeneous mixture is by adding sugar to distilled water and identify the various factors affecting solubility.

see whether all liquids evaporate at the same rate. In other words, does water evaporate at the same rate as juice?

How does salinity affect the point at which water freezes? Kids will find out by performing this cool melting ice experiment.

The objective of this science fair project is to examine the effects of temperature on salt and water solutions, as they form crystals over time.

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.

How do cold packs work? Explore endothermic reactions by comparing the temperature change that results from various chemicals added to water to find out!
