Y7 Activate - Diffusion (Movement of substances, from 'Cells' topic)

This lesson is designed for a year 7 class studying the KS3 Activate curriculum.
This lesson is focused on ‘movement of substances’ (diffusion).

From this lesson, students should be able to describe the process of diffusion, using specific examples.
Students should also be able to name two substances that diffuse into cells (oxygen and glucose) and two substances that diffuse out of cells (carbon dioxide and water).
This lesson includes a demonstration of skittles in water.

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
