A complete and ‘ready to deliver’ KS3 lesson.

Please note this is KS3 - breathing mechanism.
It is not KS4 / GCSE

Lesson objectives:

1. Describe the “process” of “inhaling” and “exhaling”.
2. Describe how a “bell jar” can be used to model what happens during breathing.
3. Explain how to measure lung “volume”.
4. Measure lung volume in the classroom (simple experiment).
5. CHALLENGE MISSION: Calculate your own lung capacity.

This is a complete lesson from start to end, you do NOT need to spend hours carefully planning and resourcing this lesson.

There is nothing to do but give it a quick read through and familiarise yourself with it, and if necessary, take some simple decisions the lesson guides you to make before delivering it. You may also wish to remove a few slides to reduce its length if required for your particular group of learners - it’s modular design makes this very easy to do.

The lesson contains:

• Need list – telling you what to photocopy or what kit to order etc
• Notes to help the teacher
• Title & lesson objectives (as above).
• Starter task where students self-assess themselves against each objective
• Scientific literacy activity
• Homework (you choose whether your learners need to do it)
• Video
• Questions – all answers are provided.
• Paired work activities with answers.
• Theory slides (minimal – interspaced with thinking activities - not ‘death by PowerPoint’)
• Practicals in groups – with scaffolding text
• Equipment list - to give to your technicians (excel file).
• Numeracy activity
• Gap fill activity – answers are provided
• Plenary formative/summative assessment activity / quiz
• Student self-assessment versus objectives activity – so learners can judge for themselves how much they have learned
