How Can We Sense so Many Different Sounds from a Distance?

How does sound travel through different mediums? Scholars explore this question by creating and observing sound waves as they learn the difference between transverse and longitudinal wave motion. Using their new knowledge, class members...

Which travels faster, light or sound? Scholars work in groups to simulate the ability for waves to travel through solids, liquids, gases, and through a vacuum. Then, they learn about the properties of a mystery wave and must determine...

The conversion of sound into light is a fascinating phenomenon that is a side effect of pistol and mantis shrimp stunning their prey. It is known as sonoluminescence, and it is thoroughly delineated in this fascinating little video. Add...

If a tree falls in the forest and no person is around, does it still make a sound? Students view a short video segment to determine sound and decibel levels of various objects, including the loudest and quietest possible sounds humans...

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....

 Introduce classes to the idea of waves with a short video clip. An interesting presentation gives a quick but thorough overview of the different types of waves and where people encounter them.

Make sound waves visible with an experiment that asks middle schoolers to build a model ear drum using plastic bottles, rubber bands, plastic wrap, and sand-like substances.

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...

Students are introduced to the forces that are responsible for generating waves in the ocean and how these forcesf differ from those that cause currents. They are able to explain how water molecules in a wave do not move in the direction...
