From Bats to Babies: Ultrasound

Physics masters figure out the wavelength of different waves. Looking at a wave graph, they identify different characteristics. Many more problems get them working with both electromagnetic and sound waves. There are a total of 17...

This wave and electromagnetism assignment is so thorough, it could be used as a unit exam. The first section of it covers wave concepts. The next section addresses static electricity. There is a section that deals with electric circuits....

Wave goodbye to the same old demonstrations for alternative energy sources, and wave hello to this one investigating ocean waves! Using a water bottle to create an oscillating water column, learners see and possibly hear how the...

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. Whole...

What is a physicist's favorite part of sports? Doing the wave. The presentation covers longitudinal, transverse, surface, and standing waves. It includes in-depth information on frequency, wavelength, period, amplitude, reflection,...

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...

In this first of two parts, Mr. Noon walks around his physics class demonstrating how sound waves move. Ironically, the sound is off from the visual in this video! Use this illustrative video to learn about different demonstrations you...

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....

This is a continuation of Mr. Noon's demonstrations on the physics of sound. Watch part one to pick up some tips on how to teach sound to your high school physicists or get ideas for activities for them to try.

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.
