According to different organizational forms, preschool children's science education activities are divided into inquiry, observation and inquiry, listening and inquiry. The activity design is as follows:

1, inquiry discussion.

In the large class science education activity "Fun Sand Water", each group can choose a small theme for scientific exploration. Because there is no unified theme, the children are very active, and the children in each group actively speak and express their ideas. Finally, through negotiation, humility and striving, each group has determined its own exploration theme. Some groups choose to build "cliffs" in sand pools.

Some groups choose to make "three-layer cakes"; Some groups choose to build "canals" in sand pools and so on. Teachers guide children's groups to learn and make inquiry plans, and each group begins to make plans according to different scientific inquiry topics. The team that built the Great Wall "crib mouth" found that to build the Great Wall "crib mouth" firmly, we must pay attention to the ratio of water and sand.

2. Observe and explore.

In the scientific education activity of "raising silkworm babies", it is found that the observation of small class children is based on interest, and the more concentrated the observation range, the more it can help children establish the habit and ability of observation. Therefore, in the activity of raising silkworm babies, the teacher designed an anthropomorphic activity "Silkworm babies build houses", which created the situation that silkworm babies want to build houses and made the cocoon phenomenon interesting.

During the activity, in order to help the silkworm build a house smoothly, the children took the initiative to build a scaffolding for the silkworm to build a house. They found some branches and put them in cartons, but after observation, they found that silkworms don't like to build houses on branches. After discussion, they think that the branches are too thin for silkworms to build houses. So, they came up with a way to tie several branches together and put them in a carton.

3. Listen to the inquiry.

In the science theme education activity "Master Imitation" in the middle class, the teacher edited a story "Pony Seeing Friends" with natural voice to arouse children's curiosity and interest in natural voice. Children look for all kinds of living materials that can be used to simulate the sound of nature.

Some imitate thunder with drums, some imitate the sound of rain with plastic bags, and some imitate the sound of pony running with castanets in the music area. Children are very excited to identify, find and explore what materials sound closer to various natural sounds, and repeatedly compare, identify and screen suitable materials.

In fact, in this process, children unconsciously and imperceptibly understand that different materials will make different sounds, and learn to recognize the timbre, pitch, sound intensity and so on of various sounds.
