Pre-listening
It’s interesting to do an experiment. But we’ve got a lot of things to do before an experiment. First, we should be clear about the aim of the experiment, the apparatus we need and how we can carry it out (we call it “method”).We watch what’s happening and get the result. Lastly it is important to have a discussion on the result of the experiment. Don’t forget to write down the conclusion.
