YEAR 8 CURRICULUM
Science
You will sit 3 formal assessments over the course of the year.
In the 2 weeks before each assessment your focus is to revise to a timetable and to use the 1,2,3 method described below.
The guide below tells you what you will need to know and understand and what you will need to be able to do for each assessment.
AT: this refers to what we would like you to secure to reach National Expectation.
ABOVE: this refers to what we would like you to master to achieve above National Expectation.
1, 2, 3 Resources:
1, 2, 3 Revision:
1. Your exercise book.
1. Rag Rate – I know this –Green, I don’t know this – Red
I have some understanding – Amber.
2. Collins connect.
3. KS3 Science Revision guide.
2. Create revision cards or Mind Maps prioritising Reds
first, then Ambers and finally Greens.
3. Practice answering sample questions to see what you
have actually remembered.
