Revision activity for the new Edexcel combined science CB2 topic and Edexcel Biology SB2. The idea of the activity is that they need to get all the questions answered on their sheet working cooperatively with the rest of class, with each person only being able to contribute one answer to each worksheet. I also allowed them to ask me to answer one question but could also be done independently amongst the students.

A worksheet to help students understand the Hardy-Weinberg Principle. Includes an explanation of what it is, a modelled answer and 2 exam-style questions (with the mark scheme also attached).

Help sheet to aid students with questions about using the inverse square law to calculate a new light intensity when the distance of a light source changes. Was designed specifically for use with the CB6 topic of the new Edexcel Combined Science GCSE course (9-1).

It includes starter questions all about osmosis, explaining certain aspects of the method, thinking about the different variables, calculating the percentage change in mass, drawing a graph, analysing results and past paper exam questions.

30 past paper six mark questions from the edexcel Biology GCSE (9-1). Includes mark schemes for each question and a slide of which topics are covered in which question for students to choose which ones to answer. Some of the questions are triple only topics, but some questions could also be used with combined groups.
