ECHO Education KS3 Chemistry

Each lesson also includes a list of the key terms and spellings that your child should become familiar with. As much as possible they should accurately learn how to spell these science words. Once they have completed the key stage 3 course and when you feel they are ready they can move onto IGCSE science courses. Our website has all the information about the 2 boards and also the combined science course. All subjects in key stage 3 science can be reinforced and supported by using the BBC Bitesize website which is available free to all. There are no set course books to accompany this course as all the content is provided within each lesson but there are many course books and revision aids available if you feel your child requires further reinforcement in any particular area. These can be found for example on Amazon.
