Why don't ants get lost? Ants, I believe everyone is familiar with them. Then who can really understand ants? Why don't ants get lost? With this question, I consulted some books. According to the book, ants leave some smells along the way after starting from the nest to their destination, and then return to the nest. Touch each other with tentacles and notify other ants. Scientists have done an experiment on this problem. Scientists first identify an ant and vigorously clean up the place where he reaches his destination along the way. When the ant came back, it suddenly stopped at the place where the smell was wiped off. Looking for something while walking in circles. People come to the conclusion that ants can tell their directions by their sense of smell. In order to confirm this conclusion, I did an experiment. I first prepared a twig about 10 cm, and put the bait-small candy on one end of the twig. I put this device near an ant nest. After a while, an ant came out to explore the road. After I led him to the stick, he went to the place where the sugar was put, as if he were smelling it. I took this opportunity to cut off the broken part of the stick by one centimeter. When the ant came back, it turned left and right where it was cut off, but it couldn't find its way home. After a while, I repeated the above experiment, and the ants still didn't find their way home. Through these two experiments, I finally know the secret of ants not getting lost. It turns out that ants can tell the direction by smell.

I always thought mimosa was amazing. It will be shy grass! A few days ago, my father gave me a surprise-I bought a pot of mimosa to give me curiosity. The leaves of mimosa look like a big piece, but if you look closely, you will find that it is made up of many leaflets scattered in pairs on the stem, in opposite directions, as if two good friends are playing hand in hand. Its bright red stems are lined with green leaves, just like a simple and elegant girl. How beautiful! "wow! Grandpa, you are amazing, you know so much! " Grandpa smiled cunningly. When mimosa is shy, it will not only curl up, but also hang its head sometimes. I suddenly returned to my room and caught a glimpse of "100,000 Acts" on my bookshelf. As soon as I opened the catalogue, I found the question of "mimosa is shy", and I immediately opened the answer. What the book said was actually the same as what Grandpa said! So this is grandpa's secret! In the book, I also know the shy protection skills of mimosa. It is not only shy when it is touched by hands, but also shy when it encounters strong winds or heavy rains. Originally, he came to me with knowledge. I want to study the beauty around me! Thank you very much for my father's surprise!

I learned from biology class that locusts are a strange kind of insects. It has five eyes, two pairs of wings and a very powerful chewing mouthparts, so it flies very fast and has a great function of devouring food. When swarms of locusts crossed the border, they flapped their wings as much as the tsunami, and a large area of crops were eaten up. The most interesting thing is the position of its respiratory organ, which grows in the chest and abdomen and breathes through the valve. I am curious about this and want to do an experiment. I also want to observe its body structure and learn about its special skills.

So, I went to the flower pond in the yard to look for locusts, because there are many weeds and insects. It took me a long time to catch a grasshopper. After studying for a long time, I still think it is too small to observe, so I let it go. I looked at each grass more carefully, and suddenly I saw a clump of grass shaking gently, and there was a big locust eating! I jumped quickly and caught it. I gently pinched its two hind legs and looked at it carefully: it was green all over, with only a small white belly, a pair of long and hard wings on its back, and a pair of film-like wings hidden below. It has two eyes like glass beads on both sides of its head and two long tentacles on the top. At first glance, it looks like a heavily armed green armor warrior.

I found a paper box and wanted to put it in for careful observation, but as soon as I put it in, it jumped out immediately. I quickly grabbed it and looked at its feet. I found that its forefoot and midfoot are short and thin, but its hind legs are long, strong and developed, so it is good at jumping.

I put it in a glass bottle with a lid to prevent it from "jailbreaking" again. I put a cabbage leaf and a pile of paper in front of it. After it found out, it crawled over slowly, touched the two things with its tentacles, then hugged the leaves of cabbage tightly, cut the cabbage with its upper jaw and ate it. Then, I cut off its tentacles, and it hesitated when facing two different things. It turns out that it really uses tentacles to distinguish things!

I typed my own original work, hee hee.
