This is a powerpoint for a lesson on the organisation of cells into organs and organs into systems. It is aimed at 16-18 year olds but could also be adpated for a younger audience. There is also a worksheet that goes with the file. The idea is that the students fill out the worksheet as you explain the powerpoint and then you print out one slide in A3 and they work in groups to name the systems of the body.
There will also benefit from using wipeable whiteboards for the plenary.
Please let me know if you like it and I will know if it is worth uploading my other lessons.
