I may have two more ideas. They seem alright to do right now, but I might change my mind the next day because I always change my mind. I was thinking of doing:
1. How long it takes for a certain type of bread to mould. Then the different variables would be different types of bread (white, wholegrain etc.). I think this experiment is a little gross though.
2. A memory experiment. Like I hold up signs that may say 'red' but really it's yellow and ask what colour it is after showing the sign to them for a few seconds. Something like that. I might change it a little bit though, a memory experiment sounds fun.
I'll think this out a little more tomorrow, and I'll ask Ms Zhang as well, so maybe by next week I'll be starting my SRP.
