Observe the structure of the plant and write a biological investigation report 5

March 12th.

Today, I took a piece of garlic and gently peeled off the white skin on the outside; Then I found an empty mineral water bottle and cut off the top piece, leaving only the bottom part; Then pour half of the water and put the garlic in again. Any idea what I'm doing? That's right!

I'm growing garlic.

March 13th.

Today, I noticed a little bit of green coming out of the head of the garlic. The garlic is about to sprout! I hurriedly changed a bottle of water, and found that the root had grown, and I took a ruler to measure it, and the root only grew a little bit, about 1 mm.

March 15th.

Today, I came to see my garlic, ah, the garlic sprouts were a small spot that was hazy and dim the day before yesterday, and I can't see it clearly, and today the green sprouts have come out, there are two of them, about 7 mm long. I was afraid that there would not be enough nutrients in the water, so I changed the water again.

March 17th.

Today, I noticed that the green shoots of the garlic have grown, about 1 cm long, and the other one has grown faster, a total of cm. When I changed the water, I measured that the garlic root had grown by 4 mm, for a total of 5 mm.

March 19th.

Today, I changed the water for the garlic. It was found that the bottom of the garlic had been soaked in water, and the thin layer of white skin had been tightly attached to the garlic, which was flesh-colored, while the upper part of the garlic was still so white without water soaking. But I noticed that the white skin stood out a little, and I guess it was about to sprout again.

March 22nd.

Today, I found that a small green shoot about 3 mm long appeared in the little point where the white skin protruded, and I was so happy that I quickly changed the water, for fear that the nutrients in the water would not be able to meet the growth of garlic. I also noticed that the two little green shoots had grown by another 1 centimeter, the tallest one was 2 centimeters, and the one that was a little short was 2 centimeters long. The garlic root also became a swirling shape.

March 23rd.

Today, I found that the green shoots of garlic are 3 mm long, the tallest one is centimeters, the middle one is centimeters, and the shortest one is 6 mm long. I can't measure the garlic root with a ruler because the root is spindled up, and I estimate it to be 6 mm long.

March 24th.

Today, I found that one of the 3 green shoots was less than 1 mm in the middle of the shoot, and I hurriedly changed the water. I took a ruler and measured it, and the longest one was 3 centimeters long, and I thought: why did this garlic sprout suddenly grow so fast?

It's been a long time to see, but I don't know what's going on.

March 25th.

Today, I found that the tallest garlic sprout had grown another 5 mm, the small green shoot that had just emerged was 2 mm long, and the middle two were 3 mm long. Finally I changed the water again.

Through the activity investigation, students can initially learn the investigation method, learn more creatures, and understand that there can be many living creatures in a small campus, but what about the whole earth? This requires us to establish the concept of serious study from an early age, enrich our knowledge, and broaden our horizons, so that we can make more contributions to our motherland in the future. Finally, let the students establish:

to protect the environment, to protect living things, to protect our homeland - the earth".

Upstairs, the child wants 1000 words, you give the whole university **, serve you, or my deleted version!

Observational report on ants using smell to transmit information

When I entered junior high school, I was very interested in the subject "Science", in the process of learning science, my favorite thing was animals, no, the teacher took us to study the second chapter "Observing Biology", I really wanted to use scientific methods to study ants that I have been interested in since childhood.

During the National Day holiday, I went to observe ants. This time gave me the opportunity, isn't that a phenomenon I want to study? I did an experiment.

I found their nests according to the route of the ants just now, put some sugar next to the nest, and saw an ant crawl over, touched the sugar with its antennae, and then excitedly returned along the same path. On its way back, it touched the tentacles of one companion and then the antennae of the others. So, a few ants got excited and ran towards the sugar, oh, "connected with their antennae", "cut off its tentacles".

I was excited. So he dropped a drop of sugar water next to an ant, and when it found the sugar water and went back to report it, it cut off its tentacles, and as a result, no matter how desperately the poor ant tried to touch the tentacles of his companion with its broken tentacles, the companion was as if nothing had happened, and did not know that the little ant had found sugar water. Experiments have proved that ants use their antennae to transmit messages, just as humans use language to connect and communicate with each other.

I love the rhododendron, she is the city flower of Shenzhen. I met her on the wide green road in Shenzhen. She was open on the pergola of the flower bed of the city hall, she hung high on the wall of the Youth Palace, she leaned out of the courtyard of the old cadre activity center, and she was waving in the wind on the balcony of the residential building.

Here it was crimson, it was her; There was a purple red, and it was also her; The ground was red, it was her; The air was pink, and it was still her. The pavilions and pavilions are all her sultry style. Decorate a beautiful and pleasant city like a garden to make it more moving.

For example, I love the rhododendron, her vitality is extremely vigorous, easy to plant, easy to raise, and easy to flourish. As long as you cut a tree in a sunny place, you can enjoy the scenery for many years. Moreover, in a southern country like Shenzhen, where the four seasons are like spring, the rhododendron can be opened all year round.

Her continuous prosperity and her unfailing enthusiasm are similar to the image of Shenzhen, the window of reform and opening up, and the city that produces the story of spring. The selection of her as the city flower of Shenzhen is really well deserved.

I love the rhododendron because it's a creeping plant. She can climb up to the wall and dance gracefully; She can also hang high in the air, just like Ziyan in the wind. The vines are neither tall nor short, and the branches and leaves are neither numerous nor sparse, setting off the flourishing safflowers, which are slender and graceful.

She is simply a symphony, a backgammon, a "Spring River Flower Moonlight Night", or "Danube Waltz", flying and fluttering in the air, trembling and echoing in people's hearts.

I love the cuckoo because of her color. Red has always been my favorite, and it goes best with green. And the blood-like red of the rhododendrons made me fall in love with it even more.

The most abundant flowers of the rhododendron are purple and red, representing her nature, which uplifts people, stimulates enthusiasm and exalts optimism. Although there are occasional pinks, and even other colors are specially cultivated, they are not ambitious.

This description of Le Rhododendron can be seen that the author has observed for a long time, he observed the place where the peanut grows, the environment in which the flower lives, and the color of the flower, and then writes down what he sees and feels in the order of his observations, using paragraphs in a comparative manner, which gives the reader a strong infection.

"I look at the trumpet flower".

I planted a trumpet flower in a pot, which is morning glory, and it is growing. Its inner leaf shape is peach-shaped.

It was planted two months ago, and now it has a purple trumpet-shaped flower.

The young shoots of the trumpet flower are pointed and explored in all directions, but the speed is very slow, and it seems that there is no change, as long as it is after a while, and then compare the position, you can find that it is moving. It's so much fun to instinctively wrap around an object that you can wrap around whenever you encounter it.

Through careful observation, I really discovered some of the mysteries of the growth of trumpet flowers, and observing the growth of plants is an unforgettable little thing, and it is also a very interesting thing.

There's nothing here, there's nothing.

1. There are many beautiful and famous flowers on the balcony of my house. But the smallest and most inconspicuous bamboo in the corner of the balcony is my favorite and most cherished plant.

2. When the leaves of Wenzhu are first born, the color is tender green, and when she grows up, the color becomes emerald green. The leaves are slightly yellowish. Look at her bigger, as beautiful as a maple leaf in autumn.

3. The branches of bamboos are tender green, and the color below is brown with a little green. There are branches on the branches, and the higher they go, the more tender they become, and when they reach the tips of the leaves, they are almost invisible at all, only a little yellow. The leaves stretch out to the left and right, and the leaves are as fine as silver needles.

No one would have imagined that such a beautiful plant could be made by nature.

4. No matter the cold or the heat. No matter the wind or rain, Wenzhu is still so strong and tenacious. Wenzhu has always been a good example for us to be a person.

The wind will only blow the bamboo more softly; When it rains, it will only make Wenzhu more beautiful. No matter what happens, he can't resist Wenzhu's perseverance.

Plum blossom Small petals, thin and strong branches, faint pink and white, wrapped around the fragrance of the body. It is a flower that blooms proudly in winter, a flower that looks more pure white in the snow, and a flower that cannot be suppressed by snowflakes. Yes, that's plum blossoms.

A flower that stands proudly in the winter snow.

In May, the season of spring and summer. The sun is shining, and the sun is shining. Spring flowers and magnolia flowers have just bloomed, small buds have emerged in the moon season, strings of pink peach blossoms, green grass, all of this, as people say, yes, I also agree, spring is indeed a season of recovery.

She gives people the feeling of tender green, light green, boundless green, and in summer, the green is deeper, it is emerald green, and the green is deeper.

However, winter, the most lifeless of the four seasons, gives people the impression of boundless white, and the snowflakes are overwhelming, sweeping in, and the pines and cypresses, which can only add a little green to this withered winter, are also covered with a thick snow blanket.

The summer flowers are only left with dead branches and leaves. There is no longer the beauty of the past, there is no longer the hunger chain of the past, there is no longer the spirit of the past, and their only remaining dwarf branches are also exhausted and panting under the pressure of the snow, and they can only wait sadly for the arrival of death.

And at this time, in the snow all over the sky, in the lament of all things, plum blossoms appeared, standing proudly in this snow. Her tall, thin branches were not affected by the wind and snow in the slightest. Proud snow and frost.

Blooming in the wind and snow, full of pride, standing upright, standing upright, letting the wind and snow blow ......

That's why I love plum blossoms, strong and unyielding. Although the winter is so cold that people are too lazy to go out, the plum blossoms bloom in the wind and snow, and the spirit symbolized by this small flower is far more noble than the colorful roses, moon seasons, and peonies in the summer.

You see that plum blossom, like pure white snow, but after the snowflakes melt, what is left behind is just a puddle of smudge, flashy, very false, and plum blossoms, she is really pure white, sometimes with a little pink, what she leaves behind is the fragrance that seems to be there. Her simplicity and elegance are not beyond the reach of ordinary people.

Look at the plum blossoms standing proudly in the wind and snow, don't you feel her beauty at all? Could it be that in the endless snow, you suddenly see a plum blossom standing in front of you, and you are not infected by her strong and unyielding spirit that is not afraid of frost and frost? Don't you think that she is somewhat similar to the strong and unyielding spirit of the Red Army soldiers?

Didn't you think that this proud snow and frost really symbolized our revolutionary soldiers, their kind of spirit and will quality of being tenacious and unyielding, brave to fight, and longing for the coming of the blizzard?
