A scientific paper-the secret of ants
Guanghan Middle School Experimental School? Class 8, Grade 8? Liang Wenjie

? There are many magical things in nature: dogs can smell their own urine and then go home; Elephants can come to their graves in advance according to hunches and so on. Many animals can find their way home, so how do ants find their way home?

? This Saturday, when my sister and I were picking fruit, suddenly my sister gave a strange cry: "Ah! What is this? " I rushed over and looked at it. "People are echoing" and screamed, "Oh, my God! What kind of monster is this? " The mother who heard the voice said calmly, "What's the strange name? This is just an ant parade! What's so surprising? " So, I said, "Yes, what's the surprise?" My sister quickly said, "No way, can't you see these ants are carrying the crumbs we just ate?" , "it is! This is indeed the crumbs we have left behind. " After careful observation, I agreed. "Look! The crumbs are so far away from their home, how can they find their way home? " I asked, puzzled. So, my sister and I discussed it word by word, and my mother smiled: "Do the experiment yourself!" " "We put a stone on the ground, blocking the only way for the ant troops to go home. We were all surprised to find that the ant actually moved its tentacles, directly bypassed the "monster" and set foot on the road home again. We want to know: Is it possible for ants to find their way home because of their tentacles? So, my sister and I found a bigger ant. Let's enlarge its tentacles with a magnifying glass, and then cut off its tentacles with scissors to see how the ants react when they lose their tentacles. Those ants who lost their tentacles ran around like headless flies, either hitting rocks or branches, and couldn't find their way home at all. In order to verify the question "whether ants use their antennae to tell the direction", we have done the same experiment several times, and the results all prove that ants can't tell the direction as long as they cut off their antennae.

? My sister and I questioned: do ants just use their tentacles to tell the direction? After careful observation, we found that ants touch the ground with their tails from time to time. We guess: it may be something secreted by ants' tails. They use their antennae to tell the direction, smell the stuff secreted by their tails and go home. ?

? To test this hypothesis, we did another experiment. When the ant moved this thing home, it wrapped the ant's tail with toilet paper, but it was not cut off. Sure enough, the ants couldn't go home and began to bump around. We did several more experiments and the results were the same. In order to make this more accurate, my sister and I searched this question on the Internet, and the answer given on the Internet is: the thing secreted by the ant's tail is called "trace pheromone", which can help the ants out of the hole find the location of food accurately and find the way home.

? There are still many mysteries in nature waiting for us to discover. As long as we are good at asking questions and keep exploring, we can find out the truth after you answer a few question marks.
