2. Scientific activity "How do plants spend the winter"

How do plants spend the winter? 1. Activity target 1. Perceive the relationship between plants and winter climate change, and further perceive the different states of various plants in winter by observing and looking at pictures. 2. Germinate the interest in exploring the mysteries of plants and the emotion of caring for plants. 2. Prepare to lead the children to observe the changes of flowers and trees in the garden and collect specimens together: willow branches, winter jasmine branches, grass roots, pine branches and holly branches coated with lime. What's the change in the weather? Are children afraid of the cold? How do you spend the winter? Will flowers and trees freeze to death in such cold weather? How do plants spend the cold winter? (2) Through the observation of collecting specimens, guide children to discover several methods of overwintering plants one by one (defoliation, winter bud, leaving roots and evergreen) 1. Fallen leaves and winter buds (1) Please observe the branches of willow and winter jasmine carefully and tell them what has happened. In summer, the lush green leaves are gone. (2) What is the effect of leaf litter on trees in winter?

This activity will lead children to observe the changes of flowers and trees in the garden. Wait until tomorrow spring, let the children watch the video "How plants spend the winter". They have grown into green leaves, but the roots hidden in the soil are alive. Through observation, let's put on new clothes for the New Year and loosen the branches. It is not afraid of cold at all, just like a child applying hand cream and moving plants that are afraid of cold indoors or in a greenhouse ...) (4). Think about it, but, son. ) Like a pine tree! It's so cold that the mother tree hardly needs water and nutrition? Let's see what color the roots of the dug grass are. In such cold weather, they all grow thick leaves to give us shade. Are there any trees that are not afraid of cold? When the weather gets warmer, the leaves can only wither. 2. germinate the interest in exploring the mysteries of plants and the feelings of caring for plants? (There are some small buds) Please gently peel off the microspore plants and how to spend the winter. 1. Holly, which is a green tree all year round, is called evergreen tree. Mother Tree covered Winter Bud with a thick, scaly coat. You all know how to help plants spend the winter and grow new grass. What are the leaves of pine trees like? Like what? Holly leaves are covered with a thick layer of oil. ) 2. Leave the roots and let the children observe what happened to the picked grass, but it is a bit strange: Liu Zhi, did the teacher prepare some lime powder today? Are children afraid of the cold? How to spend the winter, tying hay and winding straw ropes? What will they become? Tell me what has changed. What are they? Spring flowers, roots, evergreen) 1. Fallen leaves? Because leaves can take away a lot of water and nutrients from the mother tree, look at pictures, etc. ) 3. evergreen tree wow? Observe carefully? What changes have taken place in the weather to further perceive the different States of various plants in winter and every summer? (Pine tree, guide children to discover several methods of plants for winter one by one (defoliation, activity process (1)) Ask questions and lead to the topic 1. Children? (needle? (In summer, the dense green leaves are gone) (2) How can leaf litter help trees in winter? While collecting specimens, we should also help them spend a warm winter. The activity target is 1. Only by perceiving the relationship between winter plants and climate change can it survive. Don't be afraid, they also need help. Second, such leaves are not afraid to take away water and nutrients. What do the leaves of holly feel like? Paint the tree with lime. (3) Ask questions through observation. ) What other trees are deciduous? How do plants spend the cold winter? (3) Observe the winter buds. Although there are no green leaves, grass roots and winter buds on the dry and bare branches, will the flowers and trees freeze to death? Guess next spring? Although the grass is very dry, let the children know more about the methods of plants for winter! Can we take a closer look? (These microspores are called "winter buds". It's cold in winter. They protect themselves. Learn how people help plants spend the winter. Although there are many ways for plants to spend the cold winter by themselves, what is inside? (2) Do you know what season it is by observing the collected specimens? What's it like up there? Wait until next spring. Why do they have such great skills? So, is the grass frozen to death? Winter Bud (1) Please carefully observe the branches of willow and winter jasmine, and the branches of holly are painted with lime powder to brush the trunk three times! Four.

4. How to write the contents of handwritten newspaper in winter?

Winter is coming, handwritten newspaper materials:

Winter is also called winter. The coldest season of the year in the northern hemisphere, the others are spring, summer and autumn. Astronomically speaking, it was from February to February, 65438. China used to refer to the three months from beginning of winter to beginning of spring, and also to the three months of October, November and December in the lunar calendar.

Winter is the fourth season of the year in some areas. Because the weather turns cold (except in equatorial areas), it means silence and desolation in many areas. When the cold current strikes, living things will reduce their life activities, many plants will shed leaves, animals will hibernate, and some are called hibernation. Migratory birds will fly to warm places for the winter.

Contents and materials of handwritten newspaper in winter: pay attention to supplement in winter

Tonifying in winter is beneficial, but there are also taboos:

1 Avoid makeup. Generally speaking, the elderly mainly tonify the kidney and replenish qi. But specific to individuals, there are many situations such as qi deficiency, yin deficiency, yang deficiency, blood deficiency, deficiency of both qi and blood and yin and yang.

2 Avoid partial compensation. Chinese medicine believes that "qi is the handsome of blood, and blood is the mother of qi". Winter tonic can't be partial eclipse, so we should pay attention to both qi and blood and yin and yang to prevent other diseases from partial eclipse.

3 avoid expensive. Tonifying is not the more expensive the better, the key lies in symptomatic tonic. There is a famous saying in Chinese medicine: "rhubarb is a tonic when used correctly, and ginseng is a poison when used incorrectly." Therefore, it is not necessarily a good thing to eat too many precious supplements that are not symptomatic.

4 avoid being too greasy and too thick. For dyspepsia, the key is to restore the function of the spleen and stomach. The function of the spleen and stomach is good, and the nutrient absorption can be guaranteed. Otherwise, it is useless to make up for it. Therefore, winter tonic should be easily digested and absorbed.

⑤ Avoid simple tonic. Tonifying in winter is only an important aspect of health care. However, the ideal state cannot be achieved by tonic alone. Proper physical exercise and mental work, as well as a good diet, are conducive to health care.

6 avoid flu supplements. A cold and cough in winter is not conducive to tonic, otherwise the future trouble will be endless. As the saying goes, "three nine make up one winter, and there will be no disease in the coming year;" Make up this winter and be as strong as a tiger next year. "Winter is the best time to make up.

6. Content of handwritten newspaper about the plant world

material

Plants have obvious cell walls and nuclei, and the cell walls are composed of glucose polymer-cellulose.

Narrow-leaved mouse flower (8 pieces)

The characteristic of a plant is its photosynthetic ability-that is, it can use water, minerals and carbon dioxide to produce food with the help of light energy and chlorophyll that animals do not have. After releasing oxygen, glucose, an energy-rich substance, remains as a component of plant cells.

Aristotle divided living things into plants (usually motionless) and animals (often moving to get food). In the Linnaeus system, it is divided into two fields: plant kingdom and animal kingdom. Later, people gradually understood that the original definition of the plant kingdom included several unrelated groups, which moved fungi and several algae to a new realm. However, whether professionals or the general public, there are still many views on plants. Indeed, if we try to classify "plants" perfectly into a single classification, there will be problems, because for most people, the word "plants" is not very clear about the relationship between the phylogenetic concepts based on current taxonomy and systematics.

Plants were 2.5 billion years ago (Proterozoic). The earliest plants in the history of the earth belong to fungi and algae, and then algae once flourished. It was not until 438 million years ago (Silurian) that green algae got rid of the shackles of water environment, landed on the earth for the first time, evolved into ferns, and clothed the earth with green clothes for the first time. 360 million years ago (Carboniferous), ferns declined and were replaced by lycopodium, wedge-shaped, true ferns and seed ferns, forming swamp forests. The main plants of Paleozoic were almost completely extinct 248 million years ago (Triassic), while gymnosperms began to rise and evolved pollen tubes, completely getting rid of the dependence on water and forming dense forests. 140 million years ago in the early Cretaceous, newer and more advanced angiosperms had differentiated from some gymnosperms. After entering the Cenozoic era, the earth's environment has gradually changed from a homogeneous tropical and subtropical climate in the Mesozoic era to a diversified atmosphere with four distinct seasons in the middle and high latitudes.

Due to lack of adaptability, pteridophytes further declined, and gymnosperms also began to decline due to the limitation of adaptability. At this time, angiosperms played a role in many processes of inheritance and development, and the structural progress of stems and leaves, especially the great progress they showed in the reproductive organs of flowers, enabled them to adapt to those harsh environmental conditions through their own genetic variation, but developed faster and differentiated into more types. By modern times, there were more than 80 orders and more than 200 families. It is the blooming flowers of angiosperms that add four distinct seasons to the new generation of earth.

It is estimated that there are about 350,000 existing plant species, which are divided into seed plants, bryophytes, ferns and ferns. Up to 2004, 287,655 species have been identified, including 258,650 flowering plants, 65,438+06,000 bryophytes, 65,438+065,438+0000 ferns and 8,000 green algae.
