Year 9 Project Homework 3As you were told at the start of this term you will be having an exam on ALL of the work you have studied

in Science in years 7,8 and 9.This homework is to help you with your revision.On the next 13 slides are details of what you have studied for each topic and websites to help you.

The exam will be on Friday 22nd May during your Science lesson. Make sure you have everything you may need: pen, pencil, ruler, rubber, calculator, protractor.

Revision Tips!Revise for small periods of time.Chose a topic, read through your notes in your pink exercise book or the pages on BBC Bitesize. Then get someone to test you or have a go at the end of topic test on BBC Bitesize.A lot of the BBC Bitesize topics have short videos and cartoons to help you understand key points.Ask your teacher for help where you find points difficult to understand.
