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....

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...

Let there be light in your classroom with a video that explains that light travels in waves, the electromagnetic spectrum contains seven colors, and the color of an object depends on which light waves it reflects and absorbs. With...

In this AC waveforms worksheet, students answer ten questions about AC voltage, frequencies of waveforms and they interpret diagrams of AC voltage.

There is a scallop that relies on sight so much that it actually has more than 100 eyes! There are many species that rely heavily on one sense or another. An online interactive resource has youth read about several of these animals. The...

In this online electricity learning exercise, students are asked 10 questions about electric current and battery energy, an online answer key provided.

Consider this online interactive activity as a way to practice the names that often accompany human anatomy, such as the crown of the head and the roof of the mouth. Learners select an anatomy word with a double meaning from a drop-down...

Conduct virtual experiments with water, sound, and light waves to determine the sine wave and patterns created in each.

The Sound and Light interactive investigates these two forms of energy. Students will enjoy exploring how sound and light are created, travel, and can be controlled.

A model for examining the simultaneity of two events where the relative velocity and the wave source, either light or sound, can be manipulated.
