The significance of science education for preschool children;

1, Improve children's understanding of the world: Science education for preschool children can help children understand the natural environment and all kinds of things in life, and make them realize the diversity and complexity of the world. Through observation, experiment and exploration, children can better understand the attributes and changes of things and enhance their cognitive ability to the world.

2. Cultivate children's spirit of inquiry: preschool children's science education emphasizes the process of inquiry, encourages children to find problems, make assumptions, design experiments, collect evidence and draw conclusions. This inquiry process can help children develop the ability to think and solve problems independently and the spirit of continuous exploration and learning.

3. Stimulate children's creativity and imagination: The experiment and exploration process in preschool children's science education is open and diverse, which can provide children with broad imagination and creative space. Children can give full play to their creativity and try different methods and ideas in the process of inquiry, thus stimulating creativity and imagination.
