| Research Abstract |
We got two results from a questionnaire about atom and molecule.
I Early understanding person is passive.
The reason is because only they believed words of a teacher. When they experienced a theoretical trial for a phenomenon, they go to the next stage.
II It is inferior to recognise on ion.
It is difficult the learning of ion in a junior high school. We examined the teaching materials about existence of atoms and molecules.
1) Analysis of Brownian movement
2) A difference of an electrolyte and a nonelectrolyte by a law of osmotic pressure. There experiments were important with the chemical history, and we need to review it as the teaching materials. We think about the teaching materials for the existence of a particle of atom and molecules to utilize a principle of membrane passage.
