Because we teach Physics as a separate subject from Y7 it is tough to find appropriate textbooks at KS3.
In Y8 we use a mixture of Johnson’s “Physics for You” and Philpott and Clifford’s “Physics 11-14”.
In Y9 we use “Physics for You”.
We’ve toyed with the idea of using Reynolds’s “Complete Cambridge Secondary 1”, but at the moment I can’t justify the cost.
All of which leaves us without a textbook for Y7 so we wrote our own as a PDF that the boys are then required to access through our VLE. Feel free to have a look and tell me what you think. (I’m not sure that every single exercise is our original work, so if you happen know where one came from, do let me know so that I can credit it – or remove it if it’s yours and you want me to!)
