Mr. C: OK, boys and girls, we’re going to do an experiment. Come a bit closer. The closer you are, the more you'll see! That's right! Now, what’s the aim of this experiment, Zhou Kai?

Z. K.: We want to find out if there's a change in weight when magnesium burns in air.

Mr. C: That’s right. So what do we need first?

Z. K.: Um... We need some magnesium. How much do we need? What about this piece? Is this piece OK?

Mr. C: No, we need rather more than that-about two and a half grams. We need a piece which is much bigger than that.

Z. K.: OK. . . And we need a Bunsen burner . . . a balance . . . and a crucible to put the metal in ... Here they all are. . . Where do we go from here?.

Mr. C: Well, first, put the magnesium in the crucible. Then put the crucible on the balance and weigh it. Mr. C: How much does it weigh? Take a look, everyone. Is it any heavier?

Z. K.: Um . . . It weighs two and a half grams. Do you want me to write that down?

Mr. C: How much more? Z. K.:1. 5 grams more.

Mr. C: And what does that mean?

Z. K.: It means that there is a change in weight when magnesium burns in air.

Mr. C: You’ve got it! Well done! So now, let’s do the same experiment with copper. Come along, Li

With me in the studio are Ann Baker, who's a teacher, Tom Grant, who’s 17 and still at school, and Tom's mother Pat. Welcome to the show, everyone. If I can talk to you first, Ann, do you think that the Internet is a good thing or a bad thing? Ann: Well, there are good and bad things about the Internet, but I think we should concentrate on the good things. The Internet has fantastic information about all kinds of things, and for this reason I think it's very good for students to use it. Interviewer: Do you allow your students to use the Internet during school time?

Ann: Absolutely! They have Internet classes once a week. It’s a chance for them to do some independent work. I make sure they have a reason to use the Internet.

Interviewer; What do you think are the bad things about using the Internet?

Ann: Well, we all know that there are some terrible sites on the Internet. We must make sure that students look for information on interesting and useful sites. Interviewer: I see. Thank you. Well, I also have Pat and Tom Grant with me. Tom, how often do you use the Internet? . Tom: Every day.

Internet, but he doesn't always study. Interviewer: What do you mean? Pat: Well, there are a lot of music sites that he likes. And he spends a lot of time reading about his favourite football team. . Interviewer: So you would prefer it if he didn't do that. Pat: No-I want him to study and enjoy himself. But studying is important. And studying from books is important.
