Science fair project that tests the correlation between outdoor temperature or weather conditions and the number of visible stars at night.

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.

The purpose of this science project is to determine which chemical best lowers the temperature of water in a cold pack and if the amount affects its use.

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

In this activity, you child will learn about how heat changes food. On the next sunny day, head outdoors to make a treat in an outside oven! Here's how:

Science fair project that determines the relationship between the temperature and the rate of cricket chirping. How many times do crickets chirp each minute?

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

Kids will learn how to make a thermometer to to explore liquid density in this great science fair project. Which liquids are affected by temperature the most?

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 animals keep warm? In this experiment, find out whether fat insulation resists cold temperatures and learn how this works in the animal kingdom.

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

This science fair project idea examines reptile behavior and to determine whether reptiles are more active during warmer temperatures.

Fudge is one of very few desserts people make at home that is actually crystalline. What happens when the fudge crystallizes at different temperatures?

Kids make strong bubbles to investigate the effect different additives have on bubble life in this cool science fair project idea.

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

Why do plants wilt? Kids will learn to think critically about what environmental factors affect plants, and what plants need to survive.

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

Marshmallows are made of sugar, water, and air pockets. Since the marshmallow is flexible, will air pressure cause it to expand when heated in a microwave?

In this insulation experiment, you'll learn which clothes keep you warm in the cold, and which make you shiver.

The objective of this science fair project idea is to determine whether frozen vegetables have more nutrients than canned vegetables.

Determine how salinity affects the circulation of warm and cold water. Note whether the warm water mixes or forms a layer with cold water.

Check out this cool science fair project idea to explore non-chemical means of preserving fruits by using thermotherapy.

The objective of this project is to examine the ways in which a passive solar house may contribute to conservation of energy.

Determine whether fresh vegetables have more calories or less calories than canned vegetables.

Learn about calorimetry, make a bomb calorimeter, and experiment with combusting different nuts to see which one produces the most energy!

A great science fair project on solar oven design that helps kids learn about solar power and solar heating.

Determine which environment keeps an ice cube frozen for the longest duration. Inspect and record your observations when cubes melt.

Is horse manure a possible energy source in a crisis? Use calorimetry to find out how much energy horse manure can produce in this science fair project.

This simple experiment serves as an introduction to the greenhouse effect.

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