Ten KS3 biology practicals that make learning fun and engaging

Are you looking for some fun practicals to do with your Year 7 and Year 8 science classes? This set of ten KS3 biology practicals will keep them entertained for weeks!

Some of the practicals are more suited to a bottom set and others require the students to design their own investigation before carrying it out. The diffusion practical (among others) can be extended to GCSE students by simply introducing surface area:volume calculations/rates of diffusion estimations.

All practicals have a place within the KS3 biology curriculum and will support student learning going into the GCSE biology science courses. Most practicals require easily accessible equipment that is not outside of the normal requisition list that you might give your science technicians. Phenolphthalein, cambomba (or elodea) and woodlice are probably the most exotic of materials to source and will have to be ordered in advance. Collection of some materials (e.g. plastic bottles to make spirometers) can be outsourced to your students who I am sure wouldn’t mind bringing in their own from home!

Have fun with it!
