Here's a thought-provoking activity to make new vocabulary words "stick" in the mind of your young learner.

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

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

This experiment examines whether storing your orange juice at different temperatures affects its acidity.

This project concerns activity happening millions of miles away, on the sun.

Is there more air particulate matter in an urban or rural environment? Test your knowledge with this science fair project.

Evaluate whether people can raise the temperature of their finger using the power of their thoughts.

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

Construct calorimeter and determine the caloric value of a sample of foods by change in temperature for each of the foods.

This science project challenges students to take learned information about weather and climate control and apply it to come up with creative ideas of their own.

This cool science fair project teaches kids about temperature, density and buoyancy using balloons that float with normal air. No helium required!

This project determines whether Styrofoam, paper, or plastic cups are best for preventing ice from melting.

This science fair project idea explores whether mint, known for its âcooling sensationâ really does lower temperatures.

The purpose of this science fair project is to investigate which food wrapping works best to keep refrigerated and non-refrigerated foods from spoiling.

This science fair project explores different types of endangered frogs, and why some are endangered while others are not.

This science fair project idea explores whether factors such as temperature and concentration affect the pH of a solution.

This project compares different liquids and the freezing, melting and boiling points of liquids.

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

Observe if dissolved aspirin will help plants grow healthier and faster in this science fair project idea.

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

Do you think heat can affect a plant's growth rate?

Learn about emulsification and bile's roles in digestion, and investigate how the digestive enzyme lipase breaks down lipids.

This science fair project idea teaches how the gases and pollution in the air affect the earth's atmosphere temperature.

Free science fair project idea that examines air pollution in local environments. Particles are trapped by petroleum jelly on microscope slides.

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

This science fair project determines what effect substances have on ice, and which of these products most effectively melts ice.

This science fair project idea determines what factors influence an individual's reaction time using a web-based timed reaction test.

Why doesn't the ocean freeze? Students answer this question by simulating the chemical composition and temperature of arctic waters in their own home.

Examine the presence of seeds in open fields. Collect seeds on socks by walking through open fields of grass or other growth. Germinate seeds on socks

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