If the delay between a sound and its echo is less than 1/10th of a second, the human ear can’t distinguish it. Through the use of a Slinky, rubber band guitar, and straws, scholars explore where sound comes from and how it travels....

Sound, vibrations, resonance, and frequency are explored as learners use music to foster scientific inquiry. They engage in three different sound experiments and follow up discussions to foster a better understanding of how musical...

Young scientists explore hearing through multiple experiments, demonstrations, and activities. They focus on the changes in hearing over a lifetime, how we can determine where a sound is coming from, and the ability to filter noises.

This well-organized lab activity introduces earth science pupils to the greenhouse effect. They will set up two experiments to monitor temperatures in an open jar, a closed jar, and a closed jar containing water. Ideally, you would have...

Dare your class to drive dissolved carbon dioxide out of carbonated liquid at different temperatures to discover if there is a difference in rate. To make this experiment more sound, have explorers use equally measured amounts of soda...

What is the connection between sound and vibration? Learners find out as they conduct a series of experiments with instruments they create. The experiment is well explained, includes modifications for visuall and hearing impaired...

View LED lights through the eyes of a scientist. Young scholars learn to view light as a wave frequency and connect various frequencies to different colors on the light spectrum. A lab activity asks groups to measure the frequency of...

Do you want to learn about how you learn? Help pupils become the best learners they can be by teaching them how their brain works. The resources available include videos about brain structure and a study guide full of activities that...
