終礼も終わり、職員室でほっと一息ついた私（SSH研究部員）のもとにかかってきた一本の内線電話。受話器を取ると、開口一番、聞こえてきた言葉は「先生、発熱しました！」　発熱？　インフルエンザ？　意味が分かるまでに３秒かかりましたが、結論から言うと、発熱したのは生徒ではなく、なんと「貝殻」でした。

　この貝殻（ちなみにシジミです）、もちろん、「世界津波の日」高校生サミットに参加予定の２年生「貝殻班」のもの。話を聞くと、先日の実験（失敗）を受け、今日もあきらめずに地学室で実験をしたものの、今日も発熱せず。がっかりしつつも、片付けをしていたところ、貝殻を入れた容器がほんのり温かいような... そう！　「貝殻＋水」が反応して発熱するまでには、時間が必要だったのです！！

　「発熱」に大盛り上がりの地学室では、貝殻班の３人が赤外線サーモグラフィカメラを使って発熱の様子と温度を記録しています。温度は31℃から32℃、33℃、１秒に１度くらいの速度でどんどん上昇しています。ついに40℃を越えました！　さて、何℃までいけるのでしょうか？

　「失敗は成功の母」ー誰もが知っていることわざですが、今日の実験に成功して大喜びする生徒たちを見て、こちらまで嬉しくなった出来事でした。

　　After the closing assembly, when I (a teacher) was having a cup of tea in the teachers’ room, there was a sudden phone call, saying “We have a fever!”  - Who’s got a fever? Flu? It took me a while to figure out what it meant, but as it turned out, it was not a student who had a fever, but a “shell.

　The shells belonged to the “shell group” which will participate in the “World Tsunami Day” high school students' summit in Oct. The students told me that, after their failed experiment the other day, they had another try today, but again no heat had been generated. Disappointed, they were cleaning up when they noticed that the container in which they had placed the shells seemed to be slightly warm... Yes! It took some time for the “shells + water” to react and generate heat!

　In the Earth Science Lab, three members of the group were excitedly recording the heat generation and temperature using an infrared thermography camera. The temperature was rising rapidly from 31°, 32°, and 33°C, at a rate of about one degree per second. Finally, the temperature exceeded 40°C! Now, how high can it go?

　”Failure is the mother of success” - everyone knows this proverb, but seeing the students overjoyed by the success of today's experiment was an event that made us happy as well.
