Important and difficult points in the activity

Know the form of water and understand the little secrets of pigments being dissolved and discolored by water.

Through the magic game, you can experience the phenomenon of mixing two colors to create a new color and experience the fun of discovery.

Activity process

(1) Importing the game

1. Teacher: Today, the teacher brought something. Look, what is it? There is something in the bottle What? What does water look like? (Colorless, transparent, flowing, odorless)

Teacher summary: Water is transparent, colorless, odorless, and flowing.

2. Teacher: Water babies are so fun. Now it wants to play a magic game with us, but we have to say a nice saying together, "Water baby, change, change, water baby, change, change, change." Only then will he change. Let's try?

(The teacher first shakes the bottle sideways, depending on the child's condition, so that the water contacts the paint in the bottle cap)

Teacher (mysterious tone): Wow, how is the water baby? It changes color! What color does it change? Do you want to play?

(2) Exploring excitement

Teacher: The teacher has prepared a lot of bottles. Listen, each child takes a bottle, and we will do magic together. Be sure to say "water baby, change, change, change."

1. Children take a bottle and shake it gently to make it change color. (Teacher guides and encourages children)

Question: Has your water baby changed? What color has it changed? (Children communicate and discuss)

Put a color mark on your water baby Bar. (The teacher speaks while the child operates)

2. Color correspondence

Teacher: The water baby is tired from playing and wants to rest. I will help it find a home, the red water baby. Live in the home marked with red, children, please look at the mark and find a home for your water baby. (Place corresponding to the basket)

(3) Interpretation of the secret

Teacher: It’s so strange, how can the water baby change color? (Children guess) There must be a secret, let’s come quickly Find (the teacher shakes the bottle without paint and the bottle with paint at the same time, and tries again)

Questions:

1. What did you find?

2 .Why didn’t this bottle change, but the other bottle did? (Children’s guess)

Teacher’s summary: Haha, actually the teacher put a secret in the bottle cap. (At the same time, open the bottle cap and let the children say: What secret did you discover?)

Teacher’s summary: It turns out that the pigment in the cap becomes colored water when it is dissolved by water, and of course there is no pigment in the cap. It can’t be changed.

(Word: Dissolve)

3. Open your lids and take a look. Why do some children still have paint in their lids?

(Teachers and children shake it again to encourage the children to use some Force)

(4) Exchange bottle caps and perceive the change of two colors mixed together

1. Teacher: See if there is any paint in the teacher’s bottle cap? Now I want to ask Another color (yellow) makes good friends with it. Do you want to know what will happen if the two colors come together? Let the children complete this miracle! (The teacher operates while talking, but does not display the result. Keep the child in suspense) Remember to tighten it, otherwise the naughty water baby will run out.

2. Children exchange bottle caps, try to mix two different colors together, and observe the color changes.

Question: Has the water in the bottle changed? What color has it turned into?

Question: What was the original color of your water, what color did you get later, and finally what color did it change? What color? (narrated by children)

Summary: Wow, the colors are so interesting. It turns out that different colors will turn into another new color when mixed together! Let us bring this secret to the area Play again and create more different colors!

Reflection:

When designing the activities, take into account the characteristics of the scientific field and also combine the characteristics of the children in this class According to the situation, and based on the age characteristics of the children in the small class, I chose a scientific activity "Color Changing". After an activity, I feel that the children are very interested in this activity. The teacher motivates the children and makes the children actively participate in the activities. This is very happy, and each link has initially achieved the preset goals. But there are also shortcomings: the final link did not achieve an improvement. It only allowed the children to change colors by using two colors. When the children tried to match the colors and experienced the color changes, only individual children were asked, and there was no summary of how the colors were changed. of. Small class science lesson "Color Change" lesson plan Part 2

Activity goals:

1. In the color matching operation, the phenomena and rules of color changes are discovered.

2． A third color can be made from two pigments.

3． Be interested in color changes and try out color matching experiments on your own.

4． Develop a good habit of using bold colors and applying them evenly.

5. Willing to participate in art activities and feel the joy of painting activities.

Activity preparation:

1. Picture of blue grass, watering can and paint water for magic tricks. Pictures of vegetables and fruits without coloring - pictures of cucumbers, eggplants, oranges, etc.

2． Red, yellow and blue plastic transparent candy wrappers (or plastic transparent toy pieces), red, yellow and blue pigment water.

3． Children's book: "Color Changing".

Activity process:

1. Arouse children’s interest in color-changing games through magic.

1. The teacher shows a picture of blue grass: What color is the grass? A careless child painted the green grass blue. What should I do?

Teacher: I can use the "magic" watering can to change the grass back to its original color. Do you think it is possible? (Spray yellow paint on the blue grass)

Teacher: Who wants to give it a try? Guess what’s magical about the contents of the “magic” watering can?

2. The teacher poured out the yellow paint from the watering can and asked the children to observe and ask questions: The water in the watering can is not green, so why does it change from blue to grass as soon as it is sprayed on it? What about green? (Encourage children to explain boldly)

2. Let children know through experiments that two colors will turn into other colors when added together.

1. Organize children to share their findings and use their findings to solve the questions they just raised.

Today we are all little magicians, doing magic. And conduct operational experiments to arouse children's interest, and ask children to observe the changes in color: - Put (part of) the red paint into a clean cup, and then put the yellow paint into it. Stir with a stirring rod and ask children to carefully observe the changes in the paint and compare it with the original red and yellow paints.

Teacher: Can it become green by putting two other colors together? What color might it turn into if it couldn't turn green? (Guide children to try to operate the following sets of materials: pigment water, transparent sugar paper, and plastic transparent toy pieces)

Teacher: Green is a combination of blue and yellow, and orange and purple are How was it prepared?

3. Talk about the changes in color.

What color did you create using red and yellow? Which other group is the same as them? Same method: What color does red and blue change when they join hands? What color do blue and yellow create when they join hands?

When the children say one thing, the teacher will show them a color palette.

Red + yellow = orange

Yellow + blue = green

Red + blue = purple

Reciting children’s songs: red and yellow hands Hold hands and turn into orange to draw oranges;

Yellow and blue hold hands to turn into green to draw leaves;

Blue and red join hands to turn into purple to draw eggplants.

4. Coloring game.

1. Provide the children with seasonings in three colors: red, yellow, and blue. Ask the children to choose the corresponding colors and fill them in the small pictures of cucumbers, eggplants, oranges and other fruits and vegetables.

2. Show children’s works and ask them to talk about their operations: What colors did you mix? How did it come out?

Activities extension:

In the science area, continue to provide paints, colored transparent paper, activity record sheets, etc., so that children can do color matching experiments to further explore the changes after color mixing. , satisfy children's curiosity about color changes and generate interest in exploration.

Reflection on the activity:

Before this activity, I prepared two pieces of paper for each group: one is a mixture of two colors (three groups are red plus yellow, Two groups are blue plus yellow, and two groups are red plus blue). The other is paper with leaves, eggplants and oranges drawn on it. Each group also has a box of crayons. I started the activity by drawing grass, and then I painted the grass. When I painted the grass blue, the children immediately shouted: "No, no! The grass should be green!" I said. I asked, "What should I do? Is there any way to turn the blue grass into green?" One of the smartest boys in the class said, "You can add yellow." I also asked other children to tell me other things. method, and then demonstrated his method to the children. A magical phenomenon happened, the blue grass turned green, and the children all clapped their hands happily. In the next session, I asked the children to go to the group to try mixing two colors, and mix and color the corresponding plants. Although the results were okay, some children did not have the opportunity to try it because there was only one serving per group. You can make multiple copies of this material and put it in the science area. During area activities, you can guide children to continue trying and consolidate the experience they have learned.
