Use a variety of sensory exploration to discover the difference between solid and liquid.

Try to record your thoughts with pictures.

● Encourage children to actively and boldly express their ideas and findings.

Conditions for carrying out activities

Two black plastic bags contain water, solid toys, sand, etc. They are;

Tools for children: scissors, big basin, small basin, crayons, record sheets.

Activity flow:

Step 1: Focus on the activity-lead to the initial question.

● The teacher showed two black plastic bags for the children to observe.

The teacher asked, "Please have a look and guess. What are these two bags? "

Let the children arouse their senses, touch and listen, and then guess what's in the bag. "

Step 2: Independent Activities-Preschool Conjecture

The teacher provides each child with two black pockets.

Teacher: "Please look carefully, touch, shake, listen and guess what is in the bag?"

● The teacher shows the activity record sheet (see the resource library) and asks the children to make a guess record.

Teacher: "Please draw your thoughts on the record paper."

● Children record their guesses with simple pictures.

Step 3: Focus on activities-peer communication.

● Teachers guide children to exchange guesses with their peers.

Teacher: Children, please take notes and tell each other your guesses.

● Teachers organize children to conduct centralized communication, sum up children's ideas and encourage children to tell the reasons according to their own feelings.

Teacher: "Let me introduce my guess to you."

The teacher continued to guide: "Why do you guess like this?" "What do you think?"

Step 4: Independent activities-exploration and discovery

● Let children mobilize a variety of senses to fully experience, compare the similarities and differences between the two pockets, and distinguish the different feelings of liquid and solid.

Teacher: "Please feel it again carefully. What's the difference between these two bags? "

● Children open their pockets to verify their guesses, and teachers should pay attention to reminding children of the safety of using scissors.

Teacher: "Please open the bag with scissors and see what's inside? Pay attention to safety when using scissors. "

Step 5: Focus on activities-exchange explanations.

● Teachers organize children to discuss issues freely according to their activities.

The teacher asked, "Look what's in your pocket. Is it the same as you guessed? "

Continue to ask: "What is the water you see?"

● Concentrate the water the children take out into a big basin, let the children play with the water freely and observe the state of various items in the water.
