6. The operating materials are all made of environmentally friendly and safe raw materials, with the safety of young children as the first principle, to avoid personal injury caused by young children during the operation process;
1. Each experiment utilizes the things and phenomena around it as the objects of scientific exploration, focusing on the actual life of young children, with the characteristic of "life oriented";
2. Adhering to the educational philosophy of "learning by playing, learning by doing, and learning by trial", every experiment in undergraduate learning activities is a game that is highly "interesting" and can stimulate children`s enthusiasm and initiative to the greatest extent, allowing them to actively "play" and explore in the activity;
3. The vast majority of experiments can complete a small technological production, giving young children a sense of achievement and pride;
4. The operational materials for undergraduate activities are developed based on the age characteristics of young children, corresponding to the operational abilities of children of different ages, and have a "hierarchical" nature. In a single operation activity, if there are children who are difficult to operate, they will make semi-finished products during the survival process to avoid awkward situations where children cannot do it;
5. The theme is clear, there is a certain connection between the activities before and after, and each theme has an assessment of achievement ability, with a "purposeful" nature;
6. The operating materials are all made of environmentally friendly and safe raw materials, with the safety of young children as the first principle, to avoid personal injury caused by young children during the operation process;
