My Findings Essay 300 Words(a).

On Sunday, my mom and I went to the mall and bought a copy of the Sail Illustrated Book. When I got home, I couldn't wait to open the book, but found that the font on the book was very small, so in order to protect my eyes, I used a magnifying glass to enlarge the words. However, in the process of reading the book with a magnifying glass, I found a problem.

I've found that looking at the font with a magnifying glass has to be at a proper distance. If it is too close, the font is barely magnified, and the magnifying glass does not play a role in magnification. If it's too far away, the font is blurry and it's barely visible.

After repeated comparisons, I found that the magnifying glass is best when placed 2-3 cm away from the font, so that the font is not only enlarged, but also the eyes will feel very clear and comfortable. I also found that the size of the magnified font will change with the distance between the magnifying glass and the font, the closer the distance, the font size will not change significantly, and as the magnifying glass slowly zooms away, the font will slowly become larger. Oh!

It's so twisting that I'm almost confused!

In our daily life, we should be good at observing and discovering, and I hope that my discoveries will become more and more.

On the morning of late autumn, I felt that the weather was getting colder and colder, and this morning, because my mother had to work overtime, I got up very early with her and left the house before 7 o'clock.

In the parking shed, I saw the big brothers and sisters pushing the bicycles out, it turned out that they also got up so early, maybe they got up so early every day, but I didn't know how late I used to get up. Along the way, pedestrians and vehicles were scarce, and my mother rode fast. I saw a group of older brothers and sisters waiting for the bus to go to school under the bus stop sign, and they should have gotten up earlier to take the bus to school.

If I hadn't gotten up early today, I wouldn't have seen my big brothers and sisters waiting for the bus. If you get up early, there are not so many cars and so many people on the way to school, usually you get up late, there are a lot of cars and people, there are many people running red lights, vehicles are always honking, noisy, everyone is in a hurry.

There are really a lot of benefits of waking up early, it seems that I will get up early and not sleep lazy in the future!

My Findings Essay 300 Words(c).

One of the things I noticed in the past was that ants' teeth were black.

One Saturday morning, my friend said, "Ants' hunger is white," and I didn't believe it. I'll go to the park by myself.

Now, I went home and got ready, and then went to the park. After a while, when I arrived at the park, I searched left and right, and searched all over the park, but I didn't find any ants, me.

Don't you think ants eat? I hurriedly prepared the food, (I put salt and sugar in two basins, and in a short time a large swarm of ants came and ran by.)

Come, there are many ants that eat sugar, and when I look closely, I see that the teeth of the ants are black. I'll go home for your mom, and I'll be home in a moment. I asked my mom why.

Are the teeth of ants black? The mother said, "Because the appearance of an ant is black, so are its teeth."

I think I'm really a person who is good at discovering and thinking, and I think my findings are really interesting.

The secret of the ants is discovered.

One day, after eating a pear, I was about to throw away the leftover pear, and my mother said, "Give the kernel to the ants." "I listened:

It's winter, how can there be ants? My mother pulled me into the house, pointed to a small hole in the corner and said, "Look, it's here."

So, I put the pear pit next to the hole. After a while, the pear core was discovered by one of the ant's detectives. It crawls up to the pear pit, touches it with its antennae, and then it runs back, and on the way it meets an ant, and they touch the antennae and keep going until they get into the hole.

After a while, a large pile of ants crawled out of the ant hole, and I thought it must be an army of ants. They climbed up to the pit like a peak, worked on it for a while, and then crawled back into the hole. I take a closer look, and ah!

They're biting down on a piece of flesh with their teeth and moving it into the hole! After a while, a pear pit was gnawed out of a hole by the ants.

Why are there ants in winter? Why do you want to be on each other's tentacles? Do ants get lost in search of food?

A series of questions came to my mind. To figure out these questions, I found out the book "100,000 Whys".After careful searching, I finally got the answer to all the questions, there are ants in winter because they don't stock up enough food for the winter, and the ants will also go out and leave a smell in relatively warm conditions, and when it returns, as long as it follows the smell, it will definitely be able to return to the ant hole, so the ants will not get lost.

Yes! I found slugs.

The Secret of the Slug. Everyone has their own discoveries, and one day, I discovered the secret of the slug's getting bigger and smaller.

One evening, I caught two slugs from downstairs and happily ran home to keep them in cardboard boxes.

After a while, I noticed that one of the slugs had become smaller. Why? I couldn't figure it out. Could it be that slugs do magic? I can't help but think so.

Suddenly, I found that there was some salt in the carton and a lot of water around, which made my second monk even more confused. I tried my best to think of the answer, and I thought about it for a long time, but I still found nothing. I thought: slugs, salt, water, how can these three things be connected?

I went to the toilet and saw that a sponge was bigger than it used to be because it was absorbing too much water. That's right! A thought crossed my mind, and I ran back to the house as fast as I could, taking a closer look at the salt and water.

And sure enough, it was! I shouted. Dad rushed to me when he heard the news and asked me

What did you just shout? I said to my father, "Look, this slug has suddenly become smaller, can you explain why?"

Dad frowned, too, like I just did. I said to my father, "Dad, there's a lot of salt here, and slugs are mollusks, and most of their bodies are water, and when the slugs climb to the edge of the salt, the salt will suck away some of the slug's water, so the slugs become smaller."

I looked at the smaller slug and thought: the slug can be sucked away, but can't it absorb water itself? I took some water and sprinkled it on the slug, and after a while, the slug really got bigger, which was funny!

I think that only by being good at observation and using more brains will we be able to discover the mysteries of life.

I found out ).

When I was in the fourth grade, I had a nature class and our teacher told us that paper could be used as a pot to boil water. When I listened to it, I thought the teacher's words were ridiculous: how could paper be used as a pot?

Before the water is hot, isn't the paper burned first? But the teacher's serious appearance doesn't look like a lie to us. So I came home from school and did the experiment to confirm the results.

I went to the coal house and found a wire, and used a clamp to make a small shelf, then I found a piece of paper, folded it into a "small basin", filled it with water, and put it on the shelf, and then I found a candle and put it under the shelf, and finally I lit the candle. I stared intently at the water in the basin: two minutes had passed, and it was already dark underneath.

After another two minutes, the water was already a little hot. After another two minutes, a miracle happened - the water was boiling! The paper didn't even break!

I didn't believe my eyes, and after checking a few more times, the paper still didn't break! ka

The success of this experiment has made my curiosity even stronger, what is the reason for this? Why doesn't paper break? I decided to figure it out!

I went to the school library to check the information, and finally found the answer: it turned out that the temperature was at fault! Because the temperature required for paper burning is 130 degrees, and the water is only 100 degrees, the heat is all absorbed by the water, and the paper can't burn up!

Phr) This experiment proves that something that seems strange to you is not strange if you try to find the answer! qa^

Wow exam questions.

But haven't you taken the test yet?

Everyone may discover some mystery of something, and there will be many experiences in the process of discovery, of course, even I, a person who does not like to discover, will discover the mystery of things, if you don't believe it, please listen carefully.

It was ...... on a hot and cool summer day

My sister and I were playing by the pond. Suddenly, a small red fish jumped out, a graceful dolphin-style diving action, with water droplets like a naughty child landed on the lotus leaf, rolled, turned over, and jumped up again, a flawless diving action was born.

I think that the lotus leaf must have been wet with water droplets, and the lotus leaf has no towel, so it is easy to catch a cold, and it can't take medicine. I dried it to give it a chance to sunbathe. So, I dragged the lotus leaves out of the pond with my own mopping floors.

Touch the lotus leaf with your hand, well, fluffy, and the texture is not bad. Take a closer look, huh? How did you do it?

I didn't believe it, so I put the lotus leaves in the pond and soaked for a while, and when I picked it up, it was still dry. Is it that the lotus leaf is too hot, and when it is hot, it will be thirsty; When you're thirsty, you want to drink water, so you swallow it, right? It must be like this.

I would like to see how lotus leaves can drink water without a mouth. So, I didn't care if the lotus leaf felt cold or not, and let it soak for a while. This time, I watched with excitement with wide eyes, and my heart was still beating "thump" from time to time, for fear of missing the scene where the water droplets were eaten by lotus leaves.

However, it backfired, and the water droplets were not eaten by the lotus leaves, but "bounced" into the water like marbles.

Why don't lotus leaves get wet? "I walked into the study with questions and opened '100,000 Whys'. A check, oh, it turned out that there was a nano film composed of nanometers on the surface of the lotus leaf.

The nano film is spread on the surface of the lotus leaf, making the lotus leaf smooth, as if putting on a waterproof coat for the lotus leaf.

Copy the hope that LZ adoption!

Essay on the discovery of life for elementary school students 300 words: I discovered the secret of the sunflower.

One day, I saw that the sunflower was not blooming, so I asked my mother curiously, and she said, "I'll give you some hints, let you think about this discovery for yourself!" ”

I recorded the weather conditions of the past few days, and the weather today was cloudy, and when I took the sunflowers, it was only half open. Tomorrow's weather will be sunny, and the sunflower will bloom like a beautiful large flower bed. The day after tomorrow it was raining, and when I took out the sunflower, it bloomed slightly with petals as small as a small ant.

Today I want to take out all the sunflowers in our house to verify, and there are many varieties of sunflowers: some are red. Pink.

Yellow ......I took out so many plates of sunflowers, and each plate of sunflowers was only half blooming on a cloudy day, and when it rained, it opened weakly a little, and when the sun was shining, the sunflowers bloomed with many petals, and each one looked exceptionally beautiful.

Through my observations in the past few days, I finally know the secret of the sunflower. I happily told my mother the secret, and she was surprised and said, "My precious girl, you finally know the secret of the sunflower."

Through the experiment of Sunflower, I also learned a truth: "As long as we observe everything in life with our eyes and openly ask why, you will have unexpected gains."

My findings.

Last summer, I found a cobweb in the corner of my grandfather's house, and my curiosity drove me, so I caught a fly and put it on the cobweb.

At this moment, a spider crawled out of the corner of the wall, and the spider spat out a white ribbon from its body, wrapped the fly around and returned to the hole. I was puzzled and thought: why don't spiders eat ants when they go back to their burrows? Thinking of this, I continued to observe, but the ants just didn't come out of the hole.

Only after checking the information did I know that after the spider caught the prey, it first wrapped the prey with silk and then spit out a digestive juice, which was injected into the prey, and when the prey was killed, it would become juice, and the spider could suck it in a big gulp because the shell was not composed of proteins, so the spider did not eat the shell.

Through this attention, I understood the mystery of spider food. Although this is only a small discovery, he tells us a truth: pay attention to the knowledge everywhere, and the seemingly ordinary nature has infinite mysteries waiting to be discovered.

I'm proud of what I found.

Mimosas are not ashamed.

I went to take out the garbage that day and I saw a mimosa and I touched it with my hand, hey! It's really like a shy little girl, it closes with a swish, it's really fun! I played it a lot of times.

Hey? Mimosas are not ashamed. I was puzzled, and suddenly I saw a mimosa next to me, and I reached over again.

How does it close? Maybe it's a different breed! Why do some mimosas close and why don't?

Maybe Mimosa is tired A bunch of questions popped up in my head, which made me even more confused, so I decided to look it up online. Oh! "It dawned on me that it was like this:

There is a kind of cell fluid in the pillow, and if you touch it continuously and let its cell fluid run out, and it is too late to replenish it, there will be a situation where the mimosa is not ashamed. Alas, I failed, but I gained knowledge.

Yes! Mimosas are amazing!
