Objectives:
1. Understand how plants survive the winter and perceive the relationship between winter plants and climate change.
2. Through observation, painting, communication, etc., further perceive and perceive the different states of various plants in winter.
Event Preparation:
There is a blank piece of paper on the cardboard paper, and a number of colored pens.
Activity process:
1. Raise questions to bring out the topic.
1. Teacher: Children, do you know what season it is? How has the climate changed?
2. Teacher: In such a cold weather, will flowers and trees die in winter? Are the plants ready for winter? Next, let's take the cardboard and go outdoors to find it, look at it, and draw a picture"Winter plants"。
2. Guide children to observe plants outdoors and record plant phenomena.
1. Teacher: When winter comes, what changes do the leaves on the small trees have? What's changing in the big tree? What does grass look like?
2. Teacher: Ask the children to observe independently within the designated range, and tell their own discoveries and questions.
3. Teachers guide children to observe individual plants in a focused manner to help children further perceive the changes of plants
Observe the Big Tree: Ask the children to take a closer look at what the tree looks like in winter. Come to think of it, did they freeze to death? Find out what's left in the tree? (Guide children to discover buds, fruits, seeds, etc.) )
Teacher: Ask the children to peel off the bud and take a look, what is in it? Guess what will become of next spring?
Observe the grass: Ask the children to observe the grass in the grass and see how the grass is doing in winter. Qu, teacher. Teaching plan. Net source. Think about it, did the grass freeze to death? Dig out the roots of the grass and see what color it is? What grows on the roots?
4. Teacher: Ask the children to observe the plants carefully and record the various manifestations of the plants in winter with their own colored pens.
3. Organize exchanges after returning to the activity room.
Teacher: Ask the children to tell their peers about your records and discoveries, and see how many ways plants survive the winter.
4. Help children understand the various ways in which plants spend the winter.
1. Teacher: When winter comes, the leaves of deciduous trees fall off one after another, but the leaves of evergreens are still green; Does fallen leaves help trees survive the winter? (Reduces water evaporation, leaf litter can be turned into fertilizer, nutritious tree roots).
2. Teacher: What color is the grass? Is it dead in winter? (Some of the grass roots are dead, but it left its seeds, and some of the grass roots are still alive and will sprout next spring.) )
3. Teacher: How do people help plants survive the winter? (Lime and hay on trees, sprinkle grass ash and dry manure on rape and wheat seedlings, and move ornamental plants that are sensitive to cold indoors or greenhouses.) (This lesson plan contains supporting PPT courseware).
