Showing Results for sounds : Page 3

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.

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

Explore concepts in current and coltage with these Van de Graaff generator experiments.

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.

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

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

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