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

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

Kids will create their own version of Richard Feynman's rubber band heat engine to learn about thermodynamics with this cool science fair project idea.

Learn about calorimetry, make a bomb calorimeter, and experiment with combusting different nuts to see which one produces the most energy!
