Why this why now
This unit builds on pupils’ prior learning from Human skeleton and muscles, where they explored the structure and function of body systems. It deepens their understanding by examining diffusion as a key process for transporting substances in and between cells. This prepares pupils for the next unit, Human digestive system, where they will apply their knowledge of diffusion to understand how nutrients are absorbed into the bloodstream, highlighting the importance of these processes in digestion and overall body function.
Prior knowledge requirements
- All living organisms are made up of cells.
- All cells are surrounded by a cell membrane, which controls which substances can move into and out of the cell.
- The particle model of matter.
- The properties of the different states of matter (solid, liquid and gas) in terms of the particle model.
