In today's science class "What's in the soil", I first led the children to the playground in the back. There is a piece of mud over there. We are going to do activities on this land today. The children are very excited to take part in the excavation activities in person. Nowadays, children in society are usually far away from nature. The information about the soil obtained through excavation activities is true and reliable, and the children are convinced.

Multiple observation methods

In the process of digging, children are not afraid of getting dirty. Through their eyes, hands and nose, they really realized the fragrance of the soil and were curious about the substances in it.

biodiversity

I selected several representative things excavated by children and introduced them one by one, such as earthworms, ants and watermelon worms. Let them know their shape, characteristics and living habits, and let them know that the soil has many nutrients, which is the basis for the survival of many animals and plants. They were also told that earthworms would swim outside when it was going to rain.

ideological education

After returning to the classroom, I asked each group to send a representative to talk about what they found during the excavation and asked him to express it in complete words. In the process of expression, I corrected those incomplete words. Educate children's minds, restore the soil turned over during the experiment, and don't hurt other creatures.

Patience guidance

Some children don't know how to observe, and feel that there is nothing in the soil, so they need patient guidance and observation.
