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.
- Make decisions on what data to collect and how to tabulate it.
- Interpret data using a scattergram.
Activities
- Investigate how muscles work in pairs (biceps & triceps) using a bottle of water as a weight (Yr3&4).
- Collect data to investigate the link between leg muscle strength and either the type of regular exercise (Yr 3) or the amount of regular exercise (Yr 4).
- With guidance display data as a scattergram and use it to look for a pattern in the data (Yr3&4).
Investigation - pattern seeking, problem solving
Some of the team have had injuries and want to know what they can do to help prevent this. Learn how muscles work in pairs and investigate the question “Do people have stronger muscles because they use them more?” Make predictions, gather data, discuss, display and interpret findings.
Year 3 - Record data on a task sheet with prompts and a table for results.
Year 4 - Record data on a task sheet with fewer prompts requiring more independence.
