SCIENCE YEAR 9 S UM MER BO O KL ET Happy summer year 9! We have designed a booster pack to help you review everything that you should have learnt in year 9 and help you when you commence year 10, in preparation for your GCSEs. The activities are varied and include all the answers at the back of this booklet so that you can check your understanding, don’t look now, that’s cheating… you did, didn’t you? Moving on. If you work your way through all of these activities (some of which you may have seen before and attempt all the exam style questions, you will be in a good place in September when we return to school. We have linked GCSE pod videos to help you with your understanding, should you come across something you don’t understand and below are some links to other places you can find help. The topic headings will also help you as there will be revision resources on SharePoint for you to access to help with each topic. We want to see, celebrate and reward you for your effort!
