In kindergarten was held a week of experimentation "I want to know everything". Each day of the week was productive: the guys have learned a lot of new and interesting. During the experiment, the children were able to meet their inherent curiosity (why?, how?, what would happen if ...?), feel like a scientist, researcher and they have been enjoyed, surprised and delighted, from their large and small "discoveries". They learned to look for answers to questions, surmise and suggest during fun experiments. Funny assignments helped the children to spend time interesting and useful.
