I am a secondary science teacher and am looking for ideas for primary outreach. I am trying to design a 2hr workshop for years 4-6 that I could go into schools to deliver. I am just a bit stumped as to what topics and tasks would be suitable, the idea is to really impress the kids and to get them enthused about the prospect of secondary science. Does anyone here do anything similar and would they be happy to share ideas? Or does anyone primary trained have any thoughts on a topic you think the pupils would enjoy? I have never organised anything like this before so any help is much appreciated!!
