How to survive the winter of plants in kindergarten, there is a way for scientific plants to survive

This is also what I did, people don't know how to do things, and if they do a good job, they will freeze.

Summary. 1. This method of setting plastic bags works for some flowers with a temperature of about 0 °, especially at night when the temperature decreases, find some plastic bags to cover some flowers that can not be placed indoors, which can play a role in heat preservation.

Hello 1, set plastic bags This method works for some flowers with a temperature of about 0 °, especially at night, the temperature is reduced, find some plastic bags to put some flowers that can not be placed indoors, which can be used for heat preservation as oranges.

2. The method of building a greenhouse is not used in the south, and is mostly used in the north.

3. Foam box foam box is a good thing, as long as the roots of the plant are not frozen and damaged, there is a remedy, if you choose a potted plant, you can mix some foam residue when planting, and empty a layer of foam and a layer of soil.

4. Wearing clothesHave you ever seen some clothed trees in the forest garden, wrapped in quilts and wrapped in clothes, which can also play a role in keeping warm.

Activity 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 the different states of various plants in winter.

3. Have an interest in exploring the mysteries of plants and the emotion of caring for plants.

Event preparation

1.Courseware – Preparing plants for winter.

2.** — winter trees, straw.

3.Recording paper, some colored pens.

The process of the activity

1. The conversation leads to the topic.

1. Teacher: Children, do you know what season it is? (Winter).

Do you feel any change in the climate?

2. Teacher: Will flowers and trees freeze to death in such cold weather? Are the plants ready for the winter?

2. Guide children to observe plants 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 on their own and tell their own findings and questions.

3. Teachers guide children to observe individual plants in a focused way to help children further perceive the changes of plants.

1) Observe the big trees.

Ask the children to take a closer look at what the trees look 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. )

2) Teacher: Ask the children to peel off the bud and take a look, what is in it? Guess what will become of next spring?

3) Observe the grass.

Ask the children to observe on the grass and see how the grass is doing in winter. 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.

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 evergreen trees are still green;

Does fallen leaves help trees survive the winter?

Reduce water evaporation, leaf litter can be turned into fertilizer, nutrient tree roots).

2. Teacher: What color is the grass? Is it dead in winter?

Some of the roots are dead, but it has left its seeds, and some of the roots are alive and will sprout next spring. )

3. Teacher: How can people help plants survive the winter?

Lime and hay are applied to trees, grass is sprinkled with grass ash and dry manure for rape and wheat seedlings, and ornamental plants that are sensitive to cold are moved indoors or greenhouses. )

The way the pine and cypress spend the winter looks very high-class. They have a unique leaf structure and are designed to withstand the cold of winter, mainly by avoiding the release of moisture. The epidermal cell wall of the leaves of the plant is very thick, and the cells of the lower skin are closed when it is cold, and the root activity is reduced, which reduces the water content in the body.

Some plants have their own tips for conserving heat, and most annual plants will hide the energy in their bodies in the seeds, which will continue to multiply through dispersal. For perennials, they concentrate nutrients in their roots before winter to build up strength for the coming year.

There are some plants that do not hide these essential nutrients in the seeds or in the root system, but reduce the free water to resist the cold, such as wheat and rape in winter, and they store a lot of nutrients in their bodies.

In winter, plants reduce energy consumption and increase their ability to withstand cold. For example, conifers can survive at minus 40 degrees Celsius, which shows its strong ability to survive. In winter, we find that many plants outside wither, but don't make the mistake of thinking that plants are dead, this is their way of protecting themselves from frostbite in winter.

The wilting of plants is a manifestation of reduced water absorption, reducing the amount of water in the body.

As the weather gets colder and the daylight hours are shorter, it begins to transfer nutrients from the leaves to the branches, causing the leaves to fall and the plant to enter the dormant period. In winter, plants "take out" the nutrients they have stored before, and under the action of enzymes, break down these nutrients, with the aim of increasing the concentration of plant cell fluid, so that it will not be easily frozen.
