Store seeds under three different environmental conditions. Plant seeds in carefully marked groups, watch them grow. Compare results.

The purpose of this science project is to investigate which will grow larger plants: compost, soil and Miracle - Gro, a mixture of both.

Compare air temperature with the infrared temperature from a reflecting surface at different times of the day, in shade and in sunlight.

This science fair project idea determines if a particular chemical has an effect (increase or decrease) on the heart rate of Daphnia.

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.

In this cool project, create a lighted, scale model of the different layers of the Sun, including the core, radiation and convection zones, and photosphere.

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