今、中学１年生は「身近な物質の性質」について勉強しています。そこで、金属と非金属の性質を見つける実験を行いました。「金属は電気を通すのか、そして、磁石がつくのか」を調べました。アルミ缶やスチール缶、釘などの金属とペットボトルや瓶、木材などの非金属を順番に試していきます。すると、アルミ缶では磁石につかないのが納得いかなかったのか、磁石の間に挟む荒業を見せる場面もあり、楽しく実験することができました。これからも、たくさんの疑問を見つけ、調べていきましょう。
Currently, the seventh graders are studying the properties of matter around them. Among those, they have been conducting experiments with metals and nonmetals. One such experiment was seeing if these materials conducted electricity, or were attracted to magnets. For the metals, they tested aluminum cans, steel cans, and knives. For the nonmetals, they worked with plastic bottles, glass bottles, and wooden items. At one point the students were not convinced that the magnets wouldn't stick to the cans, so they tried many ways to get them to stay. The students really enjoyed the experiments. We hope they continue to ask questions, and seek the answers.
