When It Comes to Sound, I'm All Ears!

In 1993, five biomedical engineers in Edinburgh, Scotland, created the first functional bionic arm. In the activity, learners explore the world of bioengineering through discussion and hands-on exploration. In groups, participants...

Young scientists inductively derive Ohm's Law of voltage, resistance, and current by creating series and parallel circuits with 9-volt batteries and light bulbs. A week's worth of experiments, observation, and hands-on activities are...

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...

Hear about a great resource on sound? An interesting hands-on activity has learners construct a device that will soundproof a phone or speaker. They test out different materials to see which ones best absorb sound waves.

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....

Groups rotate through a series of stations and work with a partner to observe sound waves. Children describe sound in terms of pitch, volume, and frequency. To apply their new knowledge, the class considers how these observations can...

What would be the best place to live on Mars? A fascinating look at the geographical of Mars is sure to intrigue the future astronomers in your middle or high school class. A short video introduces learners to the different...

A website all about planetary mysteries—it's a one-stop-shop for all things, stars, planets, and space travel. Scholars read an astronomy overview to discover the page's big ideas, then choose from the plethora of resources, including...

Make music. Class members construct a simple record player using a paper cone and a pin. The resource provides a description of what is happening and why listeners can hear the sounds through the cone. 

Learners use their teeth for more than just eating. The activity shows class members how to send sound through their teeth by using an electric motor connected to a radio to generate vibrations. Biting on the motor transfers the...
