コウシュ ベツ ニ オウジタ スイヨウエキ ノ シドウホウ ( ショウガッコウ セイカツカ オ フクム ) リュウシ ガイネン ノ ハッタツ オ ハシラ トシテ

Though the word `solution\u27 is a concept expressing familiar phenomena around us, very few people use it correctly. For example, when I ask one of upper-grade children from a primary school a question: `What is a melting or dissolving thing?\u27, the answer is `sugar,\u27 `salt,\u27 `boric acid,\u27 `aluminum,\u27 `iron,\u27 `oxygen,\u27 `ice cream,\u27 `candy,\u27 `toilet paper,\u27 `glass\u27 and so on. We can\u27t distinguish between `melting\u27 and `dissolving\u27 so easily. That\u27s why we use the word "dissolving" when something makes the shape broken. There are some senior high school students or some university students who can\u27t understand the meaning of transparence and uniformity of solutions correctly. Some students think the dissolving things are so heavy that they go down to the bottom of the water after a long time. Therefore, we decided to research the growing stages about the `dissolving\u27 concept. Concretely, we make teaching plans about schools from kindergartens to senior high schools. We also argue better teaching methods on every situation of every school
