HOW I TEACH KIDS TO LOVE SCIENCE

Cesar Harada is a teacher in Harbour School, Hongkong. He has succeded to improve the way of teaching science to the kids.

Here they are his way:

First of all, he let his student imaginations wrong and wild becouse children has unlimitted ideas.
Whereas, his job are to collect, combine and make those imaginations to be workable.
Then he let students to participate in a experiment .
All the invention are based on local problems. Children think of those problem, imagine, and make the solutions.
He set an industrial mega-space to be his classroom because he want to provide a larger place for the students to make their dreams come true. In there, not only students but also adults can play and study together.

His goals are to prepare young generations who cares about enviromental problems and to preserve their imaginations that needed to invent the solutions.

this is my alternative
I am being confused with your grammar aspect especially in tenses. which one you considerably fascinate to utilize as I found some verb that leads me to other views. such as

probably you should write made(make); participated; were(are); thought(think); and were able to play and study(can)
