December 1, 2021 Colorful and Fun

Four years have passed since the start of our college`s new program. I commute to the Hakusanroku Campus all the way up from my home in Kanazawa, every working day. However, I still enjoy the mountainous scenery from the car. It is so beautiful and interesting. The change of the weather and the season makes the view from the car looks like a new piece of art every time. Autumn is my favorite season in Japan. It does not rain as often as it does during other seasons. So, I can enjoy watching the shiny sunlight kissing the colorful leaves. The other day, I saw a double rainbow from the car. It is always fun to observe a rainbow before it disappears. Colors make everything look glorious. Nature gives you the moment of reflection and meditation. If you are a person of science, you would enjoy the moment while asking yourself many questions.

I would like my students to enjoy their life and explore the beauty of the universe around them on a wider and deeper scale. Studying science and specifically, chemistry can help them do that and get the aha moment and be mesmerized by what they discover. One experiment that Year 1 students performed last week gave them the answer to questions that might have come to their minds, such as, “Why candle`s light is yellow?”, “What are fireworks made of?”, or even, “How do we know what the millions-of-light-years-far-away stars are made of?”. Flame test of different metallic ions experiment helped them know the logic behind spectrum emission and explained that each element has its unique spectrum emission. The light emitted by an element is like a fingerprint that shows its presence in different parts of the universe.

People of science do not only enjoy their observations, but they also question, analyze, and explain them. Year 1 students performed the flame test experiment twice. The first time, they did it while following the given instructions to observe how metallic ions such as sodium, potassium, copper, or lithium emit yellow, violet, blue-green, and red flame lights, respectively. They seemed to have enjoyed the flame colors. I could hear them saying words of amusement such as “oh, Wow !!” or “look at that!”. The second time, it was a lab practical, meaning that they performed the procedure independently to define five different metals present in the unknown provided salts. They did their best in following the safety procedure, making observations, and providing explanations. There was some time left after they finished. So, I showed them a firework stick with seven different colors. It was interesting to see them call out the name of metals every time a new color light appeared. That was colorful and fun!

 科学者は観察を楽しむだけでなく、疑問を持ち、分析し、解説もします。 1年生は炎色試験を2回行いました。1回目は指示に従いながら、ナトリウム、カリウム、銅やリチウムなどの金属イオンが、それぞれ黄、紫、青緑、赤の炎を出す様子を観察しました。炎の色を見て「おぉ!凄い!」や「見て見て!!」など楽しそうな声が聞こえました。2回目は実習を行いました。未知の塩に含まれる5種類の金属を定義するために、学生たちは独自の手順で実践しました。学生たちは、安全手順を守り、観察し、そして説明することに最善を尽くしました。実習が終わってから少し時間があったので、7色に変化する花火の棒を見せました。色が変化するたびに、学生たちは金属の名前を呼んでいて面白かったです。カラフルで楽しかったです。
