Kindergarten small class science water teaching plan model will become magical water.
moving target
1, using a variety of senses to preliminarily perceive that sugar, salt and water will taste bad after being dissolved in water.
2. Feel the dissolution of substances in water through operation and encourage children to express their findings boldly.
3. Children experience the fun of operation from the experiment.
Activities to be prepared
1, kettle, transparent disposable cups.
2. Sugar and fruit treasures, one for each group.
Activity process
First, the scene import theme.
1, watch the scene and discuss.
When the child is thirsty, he will perform drinking water.
Question: Do you know what he is drinking?
By the way, he mixed boiling water. Did you all drink boiled water? What do you think boiled water tastes like?

Second, children's exploration: sweet water.
1. Note for children: Please take a cup for each child and turn the light water into sweet water with sugar.
2. Communication: How did you change just now? What to take first? And then do what? Add what? Show the process of children's operation with a marker diagram.
3. Summary: It's amazing. Adding sugar to fresh water becomes sweet syrup.

Verb (abbreviation of verb) activity summary
Adding sugar, real fruit and salt to fresh water makes it taste different.
Model water turns red in kindergarten small class science water teaching plan.
Design intent
In an art activity, a child found that when a piece of red paper fell into the water, the water turned red. Children are very interested in this phenomenon, so I seized this educational opportunity, paid attention to creating an operating environment, and provided rich materials for children to explore and find out whether things fade in water, thus sprouting children's interest in scientific activities.
moving target
1, can actively participate in observation and operation activities, and find that some things in life fade in water.
2. Willing to express the observed phenomenon in words.
Activities to be prepared
1. Collect red objects in life, such as red snowflakes, red crepe paper, red wax paper, red cloth and red wool.
2, a glass of water, two cans, four cups of transparent water per person, with red objects on the cups.
3. Record a hand and a seal for everyone.
Activity process
1, magic leads to activities that stimulate children's interest.
Show me a glass of water and two jars. Teacher: Today, the teacher will show you a magic trick of water. do you want to see it ? Teacher: Here is a glass of water and two empty cans. Do you think these two cans are the same? Now the teacher pours the water from the cup into two jars at the same time and then pours it out later. What will you find? (The teacher operates to pour the water from the two jars back into the cups respectively. As a result, the water in one jar is still clear, while the water in the other jar turns red.
Step 2 find the reason
Teacher: Hey! How did this glass of water turn red? (children guess)
Teacher: Let me tell you the secret. Please close your eyes and count one, two and three loudly (when the child counts to three, open the lid of the jar and let the child find a crumpled paper inside).
Teacher: Some children said that the color on the paper ran into the water. Is it true?/You don't say. Let's take a look together.
3. The teacher demonstrated a small experiment: observe that the wrinkle paper will fade when immersed in water.
Teacher: What color is this? Now the teacher puts it in the water. Look carefully. What's wrong with this paper? While observing, teachers and students found that the color of the paper changed, deepened or faded?
The teacher concluded: things will fade when put in water, which is called fading.
Teacher: Where did the faded color go? What happened to the water?
4. Children's experiments
(1) cognitive materials
Just now, we know that wrinkled paper fades easily when immersed in water. The teacher has prepared some red things here. What are they? We do our own experiments and put them in water to see if they will fade.
(2) Introduce the operation method
Everyone has prepared four cups filled with water, and each cup is labeled with something that will tell you what to put.
(3) show the record sheet,
This is the record sheet. There are four things marked on the record sheet. After a while, if you find something that will fade, you can print a seal under the mark of this thing.
(4) Children's experiments
Each child hands-on operation, put four things into the corresponding cups, and observe whether the objects fade.
(5) Children record the experimental results.
The teacher helped the children to record the experimental results together on the experimental record sheet.
(6) Children tell the experimental process.
Let's take a look at the experimental results. Did these materials fade in water? Which materials fade easily and which materials do not fade easily?
(7) Summary
Not everything will fade in water, some are easy and some are not.
Will all kinds of paper fade? Let's do the experiment again during the activity time. Will all kinds of fabrics fade? Then let the children take a closer look at their mother's laundry and tell us what you found.
Activity reflection:
The children are very interested in this scientific activity and actively explore what will make water turn red. However, due to insufficient guidance, children do not understand the concept of fading ... some children have not mastered the usage of the record sheet. The role of the record sheet has not been fully reflected. It's also a little short to operate on children.
The model essay of small class science water teaching plan in kindergarten will change color.
