1. Year 8 Project Homework 3 This term you will have an assessment on all of the science work you have done in year 8 since September 2014. That is a lot of science to learn! This homework is to help you with your revision. On the next 6 slides are details of what you have studied for each topic and websites to help you. Your homework is to make a revision aid for one of the topics. Your teacher will give suggestions and tips on how you complete this task. The final slide has the marking criteria for the homework
