Determine which metal has the highest rate of conductivity.

This simple heat transfer experiment is a great introduction to the concepts of heat transfer and conduction.

Thermometers are how we measure temperature, and we've all heard the terms "centigrade" and "Fahrenheit" tossed around, but what do they really mean?

How does frost form? How fast does it form? Do this simple science project using a plastic glass, rock salt and some water to learn about deposition.

In this science fair project, we learn how air molecules move as a result of density, convection, and air currents.

Most people assume that cold water freezes more quickly, but could that be false? Does hot water freeze faster than cold water? Let's find out!

Bake some cookies with an oven that collects sunlight and traps the shorter wavelengths (heat!).

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

Explore joule heating and resistance vs. temperature with this cool electricity science fair project that gets kids melting ice cubes with resistors.

Determine whether magic salt is more effective at melting snow than regular salt. Pour one ounce of salt over the ice cubes, compare the melt downs.

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

This project examines the affect of temperature on viscosity and surface tension of different liquids.

What is the coldest temperature possible? In this cool experiment, you'll calculate absolute zero by extrapolating data on the temperature and volume of gas.

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

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

The goal of this science fair project is to evaluate the effect of heat on sound wave frequency.
