1. Create a safe experimental atmosphere for children.

Teachers should be supporters and collaborators of activities and should give children the right to make mistakes in experiments. Accept and respect children's opinions, interests, explorations, discoveries and explanations, so that every child can find something in every inquiry activity and have a successful experience.

2. Provide sufficient and diverse experimental materials for children.

Teachers should ensure that children can operate repeatedly, interact with objects, explore, discover and judge in the process of experiments, and find out the answers to questions by themselves. Children's discoveries come from their own tinkering and operation, so it is very important to provide experimental materials. Only a variety of materials can make children gain rich scientific experience.

3. Give children enough time to operate.

Teachers guide children to observe carefully in the experiment, pay attention to the changes of experimental materials during the operation, and also guide children to learn to record the findings in the experiment. Give appropriate guidance to children's experimental operation methods when necessary, so there should be enough time to ensure.

4. Encourage children to ask questions

Discuss with children on an equal footing and discuss problems together. Teachers should not rush to give the answers to the questions to their children, so as not to instill or disguise the contents beyond their understanding ability, nor to teach them condescendingly. Instead, they should think about the problems from the children's standpoint and understand their doubts. If the teacher himself doesn't know why, he can completely put down his face and tell the child his confusion frankly, which also shows that the teacher and the child are partners in "learning together".
