Studying Earthquakes in the Classroom

Ride the wave to an understanding of refraction! The first in a series of two inquiry-based lessons challenges learners to create transverse waves with two different types of springs. As their wave hits an object, they observe the change...

An incredibly colorful PowerPoint presents all the facts and definitions about waves that you could need for beginning physical scientists. There are several useful links to online animations of wave action. This may have been produced...

The sound waves of thunder are made when lightning very quickly heats the air surrounding it, expanding faster than the speed of sound. Learners explore waves through their own movement of string or set waves to constantly oscillate....

Young scientists investigate the scientific concepts and principles that help make common toys such as hula hoops, yo-yos, slinkies, and silly putty work. As a class, they read "Backyard Rocket Science, Served Wet" to get a look behind...

Does your lesson plan for wave properties have its ups and downs? Get some fresh ideas from an informative video! The narrator discusses PS4A, showing the must-know ideas for each grade level through concept maps and demonstrations.

Why did the waves get into a fight? They were tired of each other's interference. Scholars observe the wave patterns from dripping water, sound waves, and light waves. They vary the spacing, build barriers, and increase the number of...

Everyone knows that guitar music rocks - but why? And how? Learn about the ways a single pluck can create sounds that resonate from string, to ear, to soul with a fascinating video about the physics of sound vibration.

Three main factors determine the wave height experienced in the ocean. Scholars use a virtual simulator to alter wind speed, fetch, and duration. Each combination creates a unique wave measured in significant height.

If you are at a sports match and the crowd starts two waves that are both headed toward you at the same time, what do you do? The simulation applies the concepts of constructive interference and destructive interference to that very...

Listen in as Mia and Sam expound on sound. It is caused by vibrations and travels in waves. It has the qualities of pitch, frequency, and volume. This hip animation displays a graph to depict the frequency and amplitude of sound waves....
