KS3 ~ Year 8 ~ Energy & Work

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

The lesson begins by introducing the concept of ‘work done’, by using the example of a cyclist on a bike. The first task the pupils will need to complete is to produce a mind map of activities which require work to be done in order for something to happen. Students can discuss their ideas with their partners, they can write their ideas down into their books and then check their work against the answers provided in the PowerPoint.

Pupils are then shown the equation to calculate work done and they can work through a model question. You can work through this question with pupils on the board or ask them to try and complete it in their books, students can then self-assess their work.

The main activity for this lesson is a practical activity, the method for this practical is included in the PowerPoint presentation. Pupils will drag a wooden block across the desk a measured distance, the wooden block will be dragged initially with no elastic bands around it and then with one elastic band and finally with two elastic bands. Pupils will measure the force applied to drag the block using a Newton meter and record their results in a table (table included at the end of the PowerPoint). Using the measured distance and the force applied pupils can then work out the work done to drag each type of wooden block.

Students will now complete a ‘quick check’ task whereby students will need to complete a set of problems on ‘work done’ calculations. Once complete, students can self-assess their work against the answers provided.

Finally, students are given a worksheet of problems which have been completed by another pupil. Students will need to mark and correct the work, making corrections where necessary. This task can then be marked and assessed using the mark scheme provided.

The plenary task requires students to write a twitter message to explain what they have learned today, including #keywords.
