Daphnia Core Practical SNAB Biology A level

2 lessons taking students through the Daphnia core practical (caffeine) for Edexcel SNAB A level Biology. The first lesson looks at planning the investigation, and the second completing it. Example exam questions and mark schemes included throughout, and a large emphasis on ethics of using invertebrates. I also gave them the method sheet from the SNAB technician notes folder (not included), which is something additional to consider.
