Energy transfer through different mediums can be explained using wave and particle models

This online resource looks at the sensitivity of human hearing.

This free online hearing test measures the relative sensitivity of your ears at different frequencies using the audio capabilities of a computer.

It produces equal loudness contours or hearing sensitivity curves—the frequency response of a person’s ears and has been successfully trialled in a classroom situation where each student used their own ear plugs and computers.

The website also has a multimedia tutorial on the operation of the voice and hearing.

This online resource looks at the way human hearing works.

The resource is a video clip (1:37 mins) that explains how ears hear sound. It also includes a basic hearing test that shows how hearing ability degenerates with age and explains why.

This resource is well suited as a remote learning or homework task with students set the task of watching the video and determining if their hearing is appropriate for their age.

This online resource investigates different sound frequencies.

The resource is an instructional guide for building pan pipes made of drinking straws to demonstrate that different musical notes have different frequencies.

The instructions include how long to cut each straw for particular notes, and a guide to playing basic nursery rhymes using a number system.

This activity would make a good introductory lesson to sound waves or an extension for more able students to discuss frequencies and resonance. It should take approximately 30 minutes.

This online resource covers the many types of renewable and non-renewable energy.

The website allows students to read about the many different types of renewable and non-renewable energy in simple but effective language.

This video shows how a battery works.

The TED-EX video explains how a battery turns chemical potential energy into a flow of electrons in a wire that makes a light bulb glow.

This short animation could be useful when introducing electrical circuits, or as part of a web quest on electricity.
