This unit of work contains nine 1-hour lesson resources (plus a knowledge organiser) designed for a mixed ability year 8 class.
This unit follows "Chapter 1 - Health and lifestyle” from Activate 2, Biology.
However, it would be suitable for any KS3 curriculum studying biology.

This unit of work is designed to be engaging and interactive, with plenty of practical demonstrations and teacher models. There is a class practical (food tests) too which come with risk assessments and full, chunked instructions.
The lessons are designed so that they can be delivered by any member of staff, regardless of whether chemistry is their specialism. They are also suitable for students working outside the classroom, e.g. in isolation.

The lessons are designed to be delivered in this order:

1. Nutrients
2. Food tests
3. Unhealthy diet
4. Digestive system
5. Gut bacteria
6. Enzymes
7. Drugs
8. Alcohol
9. Smoking

All of my lesson resources contain:

• A 5-in-5 retrieval-style starter
• An interesting lesson hook, careers link, or retrieval practice to start the lesson
• Teacher input slides with dual coding and reduced cognitive load
• Teacher models
• Regular ‘check for understanding’ slides, such as hand signals quizzes
• Regular student independent practice slides, with optional scaffolds, challenges and answer slides
• A plenary task
