What did I find? The composition is equivalent to 500 words Thank you.

One afternoon, it was very sultry. I was playing with my father's "baby"-orchid on the balcony when I suddenly saw a small snail climb up a leaf. "Are snails beneficial insects or pests?" "Why do you leave a long line when you climb?" "Where are the nose and eyes of the snail?" This series of questions appeared in my mind.

So I decided to do an experiment myself to find out these problems.

"Snails are beneficial insects or pests?" I put cabbage, steamed bread, mosquitoes and so on first. In front of some snails I caught. They are probably hungry and climb on their favorite food. I saw that snails chose cabbage leaves to eat, but they didn't smell other foods. In a short time, the snail ate all the leaves of the cabbage and could be judged as a pest.

"Why do you leave a long line when you climb?" In this question, I first draw the snail's head with a leaf, and then gently touch it under my head with my hand. I didn't expect my head to retract immediately. what can I do? I was a little discouraged. My father came up to me and said, "Why, you are discouraged by such a trivial matter!" " ! Do you want to be a scientist when you grow up? "I was so excited by what my father said, and I was excited again. A way flashed through my mind. " Okay, okay. "I screamed on my hands and feet. I gently smashed the snail shell with a small stone, took out the snail body, touched it with my hand and found a vertical thing. By looking up the book in the dictionary, I know that it is a snail's foot, and that long thin line is the secretion of the snail, which helps the snail crawl.

"Where are the eyes and nose of the snail?" According to the previous method, I put a cabbage leaf on the ground and caught a snail. The snail seems to know my pain. Show me its eyes, nose, big tentacles and small tentacles. The big tentacles are eyes and the small tentacles are noses.

Through this series of experiments, I really benefited a lot! I not only discovered the secret of snails, but also understood a truth: if you want to make inventions when you grow up, you must discover problems from an early age and learn to solve them.

Discoveries in life, tiny past events. This kind of accident is often subtle. Often produced in accidental life, but also bred in accidental life, the happiness of Chinese fir forest, the discovery of wings in life, the wonderful flash of red clouds in life. Therefore, milk and tea also played a role in the process of discovering life. But it always exists occasionally. Even if you think about it, you may not find anything. In fact, this is also a colorful life.

The so-called world is full of wonders. When it comes to important discoveries, people may think of scientists, which seems far away from our lives. However, as long as you are careful, you can find intriguing scientific phenomena everywhere in your life.

In order to confirm this problem, I began to pay attention to it: I accidentally found that in winter, high wires are always tight; In summer, the wires will hang down. Why is this? So with full curiosity, I looked up information on the Internet. It turns out that this is because it expands when heated and contracts when cooled. The most interesting time-I painted at home, and it didn't take long to paint most of it. In the end, it's only left to tick the line with an oil pen. But I accidentally dropped my pen on my clothes when I didn't listen to orders. So I thought of washing with clean water. I didn't expect it to get dirty. In a hurry, I thought of wiping with a paper towel and boiling water. But I still can't get rid of that hateful stain. I walked into the kitchen unconsciously. I saw the bottle of white vinegar at first sight. I immediately thought: the oil of the oil pen is oily, and the white vinegar is acidic. You can definitely get rid of the oil with vinegar! So I dropped a few drops of white vinegar in the dirty place on my clothes. When it is dry, put it in vinegar-added water. I washed it for a while, and the oil stain was gone! The oil stains that can't be washed out after repeated washing and soaking were wiped off by a few drops of white vinegar. Another time, I accidentally poured 200 ml of oil into the water. I thought, this is terrible. My mother insisted on scolding me. After a while, the oil actually floated on the water! It turns out that the specific gravity of oil is lighter than water. A blessing in disguise is a blessing in disguise!

Give me a pair of eyes, let me see the world clearly, clearly and truly, "I can't help sighing. In this world, there are so many beautiful things worth discovering. I really want to find them all and taste the mystery of this world.
