Seismologists use the direction and arrival times of p waves and s waves to determine the distance to the source of an earthquake. The engaging lesson has students line up to form human waves. Through different movements when attached,...

Toys are great for learning about physics. Scholars use Slinky® toys to study Newton's laws of motion and types of energy. After a little play, they then model longitudinal and transverse waves with the Slinky® toys.

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....

Ninth graders differentiate between energy waves transmitted from a quarry or mine as opposed to energy waves transmitted by an earthquake. They analyze seismograms of blast events from at least two quarries or mines. The energy waves...
