Hey, I had a copy of Catalyst for Science scheme of work for Key Stage 3 on mhy hard drive...it is an amazing resource with great worksheets and full lesson plans but my hard drive has broken! No back up either so I HAVE LOST EVERYTHING.....but losing this scheme is a nightmare! I got it from an old school I used to work at in the UK and want another copy but I can't find it anywhere and it is too expensive to get in my new school! Can anybody help????
