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

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.

How does bleach kill bacteria? Kids find out in this impressive bacteria science fair project by testing different concentrations on a safe strain of E. coli.

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

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

The objective of this science experiment is to evaluate the affects of high and low heat capacity on a material's heat retention ability.
