On July 28, 2017, the 24th Techno-Science Cafe was held at the building 11 of the Faculty of Engineering, the University of Tokyo. About 50 children from elementary school to junior high school participated in this event.
2017年7月28日、東京大学工学部11号館にて第24回テクノサイエンスカフェが開催されました。小学1年生から中学3年生まで、総勢50名程の子供達が参加しました。
The Techno-Science cafe was held in two parts. In the first part, a lecture with a simple experiment was held by Dr. Hiroshi Nonaka, lecturer, Department of Chemistry and Biotechnology, with the theme of "How does it illumine?" In the second part, hands on activities with making slimes that emit fluorescence and luminescence by itself while mixing chemical agents, with the theme of "Let’s make your own glowing slime!"
今回のテクノサイエンスカフェは2部構成で行われました。前半の部では「光るってどういうこと?」というテーマで、化学生命工学専攻の野中洋講師に簡単な実験を交えた講義を行って頂きました。後半の部では、「光るスライムをつくってみよう!」というテーマで、蛍光を発するスライムや、混ぜている間に自ら発光するスライムなどの作成を行いました。
The details of the first part follows. Dr. Nonaka explained the difference between fluorescence and luminescence, and the mechanism of light emission taking firefly’s light as an example. After that, the luminescence reaction that actually occurs in the body of firefly was reproduced in the test tube. In the dark venue, children mixed solutions to make the light of firefly in the test tube and they were surprised and excited with a solution that glowed orange like fireflies.
前半の部では、野中講師に蛍光と発光の違いや、ホタルの光を題材とした発光の仕組みを説明頂きました。その後、実際にホタルの体内で起こっている発光反応を試験管内で再現しました。電気を消した会場の中、ホタルの光のようなオレンジ色に光り出す溶液を見て、子供達は驚いた表情を浮かべていました。
In the second part, we made light-emitting slimes. Initially, we made two types of slimes, one with yellow and another with pink fluorescent color, that glow under UV light. Children enjoyed making slimes with creative ideas, such as mixing two slimes with different colors to make a new fluorescent colored slime.
Finally, we made slimes that emit luminescnence. After lights off the venue, children mixed a plain colored slime with the luminescence materials in the dark venue. Children were excited and satisfied when their slimes were starting to illumine.
後半の部では、子供達と一緒に光るスライムを作りました。初めに、UV光を当てると黄色とピンク色の蛍光を発する2種類のスライムを作成しました。子供達は2色のスライムを混ぜて、異なる色の蛍光を発するスライムを作るなど、自由な発想でスライム作りを楽しんでいました。
最後に発光スライムを作成しました。電気を消して真っ暗な会場でスライムを混ぜ続け、やがて光り出すと子供達は喜びの声を上げていました。
When I read the questionnaire that the children wrote, I often found a statement saying that they were satisfied because they could understand the mechanism of light emission of fireflies. I am pleased that I could help them get interested in chemical phenomenon of light emission in depth through making slime at the techno-science café. I am also glad that I could participate this event as a student staff because this experience was a great opportunity for me to learn how to teach children and other people who does not have a basic knowledge.

最後に書いてもらったアンケートを拝見すると、ホタルの光る仕組みを知ることができてよかったという書き込みが多く見られました。スライム作りを通して、光るという化学的に奥深い現象の仕組みに興味を持ってもらう手伝いができたかなと嬉しく思っています。
