SupaScience is a website about primary school science and is aimed at years 4, 5 and 6
It is written to help children and their parents with homework or revise for school exams
It will also help with KS2 Science SAT’s which are soon to be re-introduced.
The science topic books contain detailed notes on most subjects and include assessment tests as well as handouts to fill in which could save teachers hours of work.

The science site is similar to this but written for older children (years 7 and 8)
