Lesson Planning

Teaching

• Understand how muscles work in pairs to allow movement and maintain posture.
• Investigate whether people who do more sport have stronger muscles.

Activities

1. Investigate how muscles work in pairs (biceps and triceps) using a bottle of water as a weight.
2. Investigate the question –Do some people have stronger muscles because they use them more?
3. With guidance, decide what data to collect, how to tabulate it and how to share out the work in the group.
4. With guidance display data as a scattergram and use it to look for a pattern in the data.

Investigation - exploring/analysing secondary sources
