Make a Sound Viewer

Using a home-built hydrophone, pupils investigate how things sound in water. Learners listen to sounds created in air and then compare that to the same sound picked up by the hydrophone. Individuals compare the loudness and the pitch of...

The choice is simple: create a PowerPoint presentation, write a book, or invent a compound machine. Whichever project your young scientists choose, they will be engaged in creatively demonstrating their knowledge of simple...

Planning a unit on simple machines? Save some time and energy with this collection of lessons and activities that explores how these devices are used in the real world to make life a little easier. 

A phenomenal activity on sound is here for your third graders! In it, learners engage in hands-on activities, watch video, take part in Internet activities, and complete tasks in cooperative groups in order to explore the world of sound...

Make your work as a teacher a little easier with a physical science project on simple machines. After introducing young scientists to these devices and identifying their different uses around the school, this project engages...

Set up a set of colorful liquid-filled bottles that produce sounds when tapped with a spoon. When teaching primary physicists about sound, they can experiment with pitch, comparing it the amount of liquid in the bottle. Which makes a...

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...

Have your class conduct research to learn all they can about simple machines. They use the web, take notes from a video, write a script, then make a film describing various simple machines found in real life. These videos are then...

It's about to blow! These directions are clear and easy to follow. Create a simple worksheet to guide students through the video and then have them repeat the steps themselves! Ideal for fourth or fifth graders who can follow directions....
