MIKE: Hi Sue.
SUE: Hi Mike, so what happened to you last week?
MIKE: Oh, I was sick with the flu. What’s this I hearabout a big assignment we’ve got to do?
SUE: Well, basically, we've got to find two scienceexperiments to do with a group of eight-year-oldchildren at the local primary school, and we’ve gotto complete it by the end of the week.
MIKE: Oh, that sounds like hard work. Where arewe supposed to get the ideas for these experimentsfrom?
SUE: Well, I managed to get hold of two books fromthe library.
MIKE: Oh, well done!
SUE: How about if we take a look at the experiments in this book first and see if anything lookssuitable? I can make notes as we go, about equipment and the purpose of the experiments.
MIKE: OK, let’s see, um, the first experiment is called ‘Make your own hovercraft’, whichsounds very ambitious! Mind you, you only need twenty balloons and a table - you don’t needany special engines or anything like that!
SUE: What do you do with it all?
MIKE: Er, you blow up the balloons and you balance the table on them, upside down of course,and the kids get to ride around on it. You know, the other kids sort of push them around theroom. The main purpose is to show how hovercrafts work, and how things hover around onjust a cushion of air.
