MRS GREN active learning lesson - differentiated

I teach this lesson after an introduction to animal/plant and specialised cells. I found that some classes always struggled with MRS GREN so I came up with a set of different activities to help them work out the 7 processes themselves. I laminated the instruction cards and placed them round lab with the various bits of equipment. Each student then was given one of the differentiated practical ws (SQUID = high, CRAB = mid, and STARFISH = low). The students then went round the room and completed each activity and writing the relevant word on their ws. We then went through answers & ppt in class to get a correct list of MRS GREN. Students then got into their ability groups and used MRS GREN to work out if various objects were living or not - group task sheet. This worked extremely well and I've found that students have a much better grasp and retention of this topic after this active lesson compared to me just talking.
