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 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.Passage B – Pre-readingCan we put nails in wet air?Iron nails rust in wet airPut the words in the right orders of the experiment report. An Experiment Report
