Hello, I am a PGCE student and need work with a small group on a simple science experiment as one of my tasks. I have seen lots of lovely experiments online but they are not that suitable for what I need. The requirement is that it is a simple investigation for y3, that we are measuring something ie length, height, distance, time and that it is relevant to real life. Ideally I'd like to give a context for the investigation so they believe we are helping someone by doing our investigation. Also, that I can do it with a small group - about 6 children, in an afternoon and that they can then present the investigation to the class. I am struggling for ideas! Can anyone point me in the right direction? Many thanks!
