KS3 ~ Year 7 ~ Waves

This lesson is designed for the Activate KS3 Science Course, specifically Year 7 P2 ’Sound’.

For more lessons designed for KS3 and KS4 please visit my shop at: https://www.tes.com/teaching-resources/shop/SWiftScience.

Students will firstly be introduced to the main features of a wave - amplitude, frequency and wavelength. Students can sketch a diagram of a wave into their books and take notes on the main features.

Students are now introduced to transverse and longitudinal waves, students will need to know the differences between the direction of the oscillations of these two waves. Students are then asked to discuss how a ‘slinky’ could be used to demonstrate these two waves, after a short class discussion students can be shown an animation to demonstrate how a slinky shows these two types of wave. Students will now get into groups and come up with a short role-play to demonstrate the differences between these two waves.

Students will now complete a progress check where they will need to copy and complete a paragraph to summarise what they have learned so far this lesson. This task can then be self-assessed using the mark scheme provided.

A diagram of a longitudinal wave which shows the differences between rarefactions and compressions is shown to students, they will then need to answer a set of questions. The answers to this task are included in the PowerPoint so students can self-assess their work once it is complete.

Next, students will need to ‘Think > Pair > Share’ their ideas about what happens when two or more waves join together. Students can discuss their ideas first before being shown a video demonstrating the process of superposing waves. Students will then complete a fill-in-the-blank task to summarise what they have learned this lesson.

The plenary task requires students to write a WhatsApp message to tell their friends what they have learned this lesson.

All resources are included at the end of the presentation. Thanks for looking, if you have any questions please let me know in the comments section and any feedback would be appreciated :)
