Why cells? Of all the starting points that we could choose for our new secondary school students, it always seems to be cells. Of course, there are many schools that implement a project type 'Working Scientifically' topic to ease students into the big world of Secondary Science, but thinking about hardcore content and concepts, every school I've been at (and every Y7 SOW I've seen) has always started with Cells. Don't get me wrong, I have nothing against cells - I'm a biologist (or so says my PGCE) But surely particles would be a better starting point no? Maybe even move on to elements and compounds before cells?! Both of these will help to explain concepts like diffusion and respiration when it comes to it in the biology topics. If anyone has any other experiences of a KS3 Science teaching order, other than the standard text book format, I would love to hear about it. What order do you think is easiest for students to follow. Is atomic structure too hard for KS3 students to follow, or a fundamental base for building other concepts upon like static electricity and light?
