KS3 ~ Year 8 ~ Gas Pressure

This lesson is designed for the KS3 Year 8 Science course, specifically the P2 1.2 unit on ‘Motion & Pressure’.

More Biology, Chemistry and Physics resources can be found in my TES Shop: https://www.tes.com/teaching-resources/shop/SWiftScience

The lesson begins with a demonstration - the collapsing can. Students should hopefully be able to identify that the can that collapsed had a lower pressure inside the can than outside the can, causing the can to collapse inwards.

This leads into a description of gas pressure, including a diagram to help demonstrate the concept. Students will now ‘Think > Pair > Share’ their ideas about what could cause an increase in pressure, after a short discussion the answers will be revealed to students - increasing the number of particles and increasing the temperature or reducing the size of the particles.

Students will now complete a task based upon what they have learned so far this lesson, this can be self-assessed using the mark scheme provided.

Students will now complete an investigation called ‘What makes a ball bouncy?’. Students will investigate whether a ball becomes more bouncy the more/less pumps of air it has in it. Students will copy the table of results into their books, draw a graph of their results and complete analysis questions. This task can be self-assessed once complete.

Lastly, students are introduced to the idea of atmospheric pressure and shown a diagram which represents the density of air particles at the top of the mountain compared to the bottom.

The plenary task requires students to complete one of the sentence starters in their books to summarise what they have learned this lesson.
