How was your placement? 00:00:02,880 It went really well. The kids really enjoyed the science I did with them. 00:00:07,600 So did mine. I think they found it very motivating. 00:00:11,040 Yes. The program we had to teach was much better than the old-style science experiments we did at school. 00:00:18,320 Yes, though I don't understand why the children should have to build a model of a steam engine. I tried it with the kids, but I couldn't get it to work. 00:00:26,460 Me neither. And it really shows it's hard to get any real results. 00:00:31,040 Yes. And it's usually the children's parents, rather than the kids themselves, who favor that type of experiment. So what experiments did you do? 00:00:40,800 Well, one day a discussion started in class about breakfast cereals, about which one was best. One child then said that we should test them in class. 00:00:52,100 That's a nice idea. 00:00:53,380 Yes, and it wasn't expensive. We brought four different brands of cereal and had everyone evaluate them for taste, appearance, and sogginess in milk. 00:01:04,420 And are you going to tell me which one won? 00:01:06,940 No. I'll let you do it yourself. It obviously isn't difficult to set up. Another experiment we did, the sports teacher's idea actually, was to spend a morning seeing how high various balls bounced. For example, do new tennis balls bounce higher than old ones? And do basketballs that are fully inflated bounce better than flatter ones? 00:01:32,360 And I guess you got some interesting data. 00:01:34,820 We did. And they had to make a chart to plot the results. It really improved their grasp of charts and graphs and calculation. Apparently, they'd had problems understanding the point of graphs in the past. 00:01:49,090 Did all your experiments work out okay? 00:01:51,860 Well, we had one lesson on making paper from grass. The children made a terrible mess in the classroom. Whatever they did didn't work, and it wasn't because it was difficult. I think it was because it didn't engage them at all. It didn't seem to motivate them. 00:02:11,220 My tie-dying experiment went well. They had to get a piece of material and twist it into a rope and then dye it. The children did end up with blue and green hands for a few days, though. 00:02:22,980 But don't you need to spend more than one lesson on that? 00:02:26,260 Yes, we did it over three classes. The children really loved it, though, and one suggested we make scarves from the result. I declined as my sewing skills aren't up to much. 00:02:38,010 I guess the one experiment that everyone loved in my class was making glue from milk. I thought it would be a complete failure, but in fact, it worked brilliantly. One reason I suspect is that they got feedback straight away. Some children get really restless if they have to wait for anything interesting to happen. 00:02:58,600 Yes, I think that's always a good idea. Really helps to make it a success. 00:03:06,260 Before you hear the rest of the discussion, you have some time to look at questions twenty-seven to thirty on page seven. 00:03:34,200 Now listen and answer questions twenty-seven to thirty. 00:03:41,520 I see you've got a diagram there for one of your experiments. 00:03:45,200 Yes. It was an idea I got from the Internet. It was very easy and straightforward to set up. The idea is to make a condenser to extract essences from plants. The large container's made of metal. 00:03:58,140 Right, and that holds the hot water? 00:04:01,310 That's right. And it has a strainer which sits inside it. This is where you put the plant matter. We use plants like rosemary, as the essence you can extract is quite strong. 00:04:13,560 So what's the container right at the top? 00:04:16,440 It's made of glass. It's where we put the ice. The glass container has a drip tip at the bottom. 00:04:23,460 What's that for? 00:04:24,900 It's where the essence collects. 00:04:27,060 Where does the essence go then? 00:04:29,180 Into the dish at the bottom. It's made of pottery. 00:04:32,420 Sounds good. I might try it with my class. 00:04:38,780 That is the end of section three. ## 题目与答案 ### 21.
