In this cool science fair project, kids apply basic algebra to learn how to make a PVC pipe instrument while exploring concepts like frequency and resonance.

In this cool sound resonance experiment, learn about frequency and pitch, and use a tuning fork to calculate sound velocity in air.

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.

What's the difference between a microwave and an oven? Use mashed potatoes to explore which kitchen appliance does a better job at keeping food warm.

Science fair project that studies how the brain transforms man-made symbols into meaningful concepts.

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

Young physicists learn about apparent weightlessnessâthat weird sensation you sometimes feel in elevators, turbulent airplanes, and roller coasters.

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

The objective of this experiment is to identify common materials that absorb sound waves with the greatest efficiency.
