KS3 ~ Year 7 ~ Sound & Energy Transfer

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

Students will firstly recap on the differences between a solid, liquid and gas. Students will need to identify the correct particle diagram from a selection. This then leads into a description of how a sound wave is made, students are asked to ‘Think > Pair > Share’ their ideas about what is meant by terms ‘vacuum’ and ‘medium’ - the answers can then be revealed on the PowerPoint for students to mark their work.

Students will now watch a video of the ‘Bell Jar’ experiment, students will need to consider what is happening as they watch the video, they could try to write their ideas down in their books. An explanation of what they have observed can then be revealed using the PowerPoint.

Students will now watch a video on the movement of sound waves through solids, liquids and gases. Whilst watching the video they will need to answer a set of questions, the mark scheme for this task is included in the PowerPoint for students to assess their work once it is complete. This is followed by a worksheet of questions, the answers to this is also included in the PowerPoint for students to self-assess their work.

Students will then complete a progress check task, this is a copy-and-complete task which summarises what they have learned this lesson. This task can then be marked and corrected using the answers provided.

Lastly, students will be asked to consider which travels faster - light or sound. They will need to think about evidence to support their ideas. The answers can then be revealed - light is faster than sound, with evidence such as you see lightening before you hear thunder, also when a starting pistol is used you see the smoke before you hear the bang.

The plenary activity requires students to write down three facts, three key words and one question to test their peers knowledge of 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 :)
