We are specialized in developing infant science courses, and the intellectual infant science is independently developed by us. But I really don't know how to answer your question. Water is a combination of hydrogen atom and oxygen atom, and h2o is the molecular formula of water. What do you want to teach children about this lesson plan?

In our course, I will give two examples related to water:

1, dirty water filtration: dirty water is filtered to form clean water.

2, bubbling water: through acid-base reflection, carbon dioxide bubbles will appear in the water.

It can be seen from these two experiments that the principle is clear, the purpose is clear and the operation process is clear.

Your goal can be to form liquid water by steam cooling, or by hydrogen-oxygen reaction, or by squeezing the roots or seeds of hydrous plants. However, in these schemes, the teaching materials are not easy to handle, and steam is also in danger of scalding.

Therefore, it is too broad to set the teaching objectives in this way, and it is difficult to form a teaching plan.
