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

Learn how to make a hygrometer to measure relative humidity in this project. Make a sling psychrometer hygrometer with gauze, thermometers, and a bottle.

Look for a correlation between temperature and the intensity of cricket chirping. Measure ambient temperature and sound intensity in decibels.

Investigate the advantages of the use of ceramics in engines such as the tiles used in Space Shuttle. Use iron filings and magnets.

The objective of this experiment is to evaluate the effects of acid rain on plants.

The objective of this science project is to examine the factors that affect the dispersion of oil in water, including water agitation.

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

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

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.

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.
