When creating this site, it was originally my intention to populate with some KS3, Biology & Chemistry resources.
However, I now more or less exclusively teach KS4/5 Physics. There are still some useful things on each of these pages though (in particular Lauren Edwards has shared some fantastic resources on the Biology page).
If you would like to contribute some KS3, Biology or Chemistry resources (in a similar format to my physics ones) then please do get in touch (@edmunds_dr on twitter). I would love to host more science resources here!
