Science fair project in which you will examine how crystals are formed by creating your own crystal using charcoal briquettes, salt, and ammonia.

Science fair project that compares the freezing temperature of salt water and freshwater in order to learn about supercooling and condensation nuclei.

In this science fair project, we'll use a liquid crystal thermometer to find out whether exercising makes a difference in people's temperature.

Science fair project that examines how temperature affects density and how density in turn affects the behavior of helium gas.

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!

Here is a fun middle school science project on factors affecting solubility. Learn how dissolved solids can "crash out" to form crystals when conditions change.
