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).

New Edexcel Science GCSE, CB2 topic looking at Mitosis. Lesson includes looking at what mitsosis is, the stages of mitosis and looking at slides using a microscope. *All of CB2 can be found together here (https://www.tes.com/teaching-resource/edexcel-cb2-11282994)*

Chapter 24 unit from the OCR Biology A A-Level all about populations and sustainability. The unit was planned with the intention of carrying out flipped learning whereby students do pre-reading on the topic prior to the lesson so that we can consolidate that learning with activities/exam questions during the lesson. Including: 24.1 Population Size 24.2 Competition 24.3 Predator Prey Relationships 24.4 Conservation and Preservation 24.5 Sustainability 24.6 Masai Mara 24.7 Terai Region of Nepal 24.8 Peat Bogs 24.9 Environmentally Sensitive Ecosystems (split into two lesson, Galapagos Islands and Antarctica in lesson 1 with Snowdonia and the Lake District in lesson 2)

Revision booklet and an accompanying PowerPoint for the CB1 core practical all about osmosis in potato slices. 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.

Lessons for the 8D topic in the new exploring science scheme of work looking at unicellular organisms. There is some reference to the exploring science worksheets (but these could be easily replaced by other worksheets you have) and to the exploring science video’s on the ActiveTeach website (which could again be replaced by other YouTube links)

CB7d lesson for the new Edexcel science GCSE (9-1) all about hormones and the menstrual cycle. The lesson includes what hormones are involved, where they are released from, what they each do and examples of assisted reproductive technology (clomifene and IVF).

Double sided A3 worksheet intended to help with revising the CB5 topic from the new Edexcel science GCSE (9-1).
