1. Perceive the phenomenon of oil and water pouring and separation after stirring through operation, and be interested in scientific exploration activities.
2. Understand the relevant phenomena of oil-water separation in life, and experience the application of scientific knowledge in life.
Event Preparation:
A bottle of water, a bottle of oil, a chopstick, and a drawing drawn with an oil pastel for each person; a number of various pigment waters; a seagull headdress; Illustrated several.
Activity process:
1. Scenario import

Use storytelling to guide the children to understand this idiom, and finally tell the children the truth of this idiom. At the same time, it is also possible for children to divide the idioms they have learned recently into positive and derogatory words to play solitaire games or cars, so that children are also interested in remembering these idioms, and they are also playing while learning, I believe that the children are very happy.
