I took part in the socialpractice trip to Qianlingshan. We visited the geological section and learned about rock strata. Deeper layers of rocks are older. My favorite activity was fossil digging. I saw models of trilobites and ammonites.

At the limekiln site, I learned how limestone becomes lime through hightemperature burning. Lime can be used for building walls and improving soil. We also played fun team games. This trip taught me to protect fossils. It was a meaningful outdoor lesson for me.

Our school went to Qianlingshan for a oneday field trip. Rocks are like Earth’s diaries that record ancient history. Fossils are secrets of ancient living things. Ancient animals were covered by mud and turned into fossils over millions of years.

I drew my favorite ancient creature on my task sheet. At the lime kiln ruins, I learned many daily uses of lime. Team games helped me learn about teamwork. This trip opened my eyes. I hope to explore more interesting earth science in the future.

 赵又平Class 4-1

On October 15, I joined the Qianlingshan study trip. Earth has a very long history. We saw pictures of pterosaurs, the flying reptiles that are not dinosaurs.

I enjoyed the fossildig experience most. Later we visited old lime kilns and understood how lime is produced. We played interesting group games together. I got a small crystal souvenir. I realize we must protect geological relics. This fantastic outdoor trip brings me lots of fun and useful knowledge.

The Qianlingshan field trip was unforgettable. We explored Guanyin Cave and learned how peak forests and underground caves form. We followed safety rules all the time during hiking.

I recorded rock information on my worksheet. We discussed the chemical change of limestone at the limekiln site. In the museum, I learned the Cambrian life explosion and different kinds of fossils. As students, we can tell friends not to collect wild fossils. This science trip makes me more interested in geology.

I really enjoyed my study tour to Qianlingshan. Inside Guanyin Cave, I saw amazing karst landforms shaped by rainwater over thousands of years. While climbing mountains, I carefully observed rocks around me.

We learned lime‑making history at lime‑kiln ruins. The poet used lime’s whiteness to praise noble personalities. The fossil museum showed me how ancient lives turned into fossils. We should not take fossils away. This outdoor class helps me better understand our planet’s long history.

                                   罗睿珊Class 5-1

I visited Qianlingshan Geopark for social practice. We had a cool caveexploring activity in Guanyin Cave. I learned that weak acid rainwater slowly dissolves limestone and forms karst caves.

We hiked up the mountain, at the limekiln park, we talked about Song of Lime. Highheat burning turns limestone into new material. In the fossil museum, I learned about mineralization and how fossils are formed.Fossils are nonrenewable. We should protect them and never dig them privately.

This autumn trip to Qianling Mountain in Fengtai was such a surprise for me. I loved the "treasure hunt in the cave" most—we held flashlights and searched for the treasure in the cool rock cave, and our science teacher told us how the limestone here formed over millions of years. My legs ached a lot when we walked down the mountain, but none of us complained. Walking side by side with my classmates, I knew this would be one of my best memories in primary school.

赵志行, Class 6-1

I have heard of Qianling Mountain many times, but this school trip let me experience it for real. When our guide explained how the rocks on the mountain formed, I suddenly realized that every stone we touched was a story from thousands of years ago. We shared snacks and laughed all the lunch break, and even the tiredness from climbing became a happy thing when we stayed together. It’s such a warm end to our final autumn trip in primary school.

这次千灵山秋游，我印象最深的就是下山的那段路。一开始还蹦蹦跳跳的，走到后半段小腿已经开始发酸，身边的同学也都在小声揉腿，但没有一个人喊累要停下。路上我们还在岩洞里完成了寻宝任务，老师蹲在地上给我们讲岩石的风化和沉积，原来我们今天走的每一步，都踩在千万年的地质痕迹上。作为六年级的秋游，和全班同学一起爬完这座山，大概会是我小学里最舍不得删掉的记忆。

 邰敏佳Class 6-1

之前总听爸妈说千灵山在丰台，这次跟着学校来才真正摸到了它的样子。最有意思的是导游老师指着山上的岩石给我们讲形成过程，原本灰扑扑的石头，在她嘴里变成了几亿年的“时光标本”。午餐的时候大家围坐在石阶上，你分我一块薯片，我给你半块橘子，平时在教室里没说上的话，都在欢声笑语里说完了。虽然爬到山顶的时候累得满头汗，但吹着风往下看的时候，只觉得所有的疲惫都值

姚光哲，Class 6-1

这次千灵山秋游最让我难忘的，是半山腰的“洞中寻宝”活动。我们跟着老师钻进阴凉的岩洞，头戴小手电，在凹凸的岩壁缝隙里寻宝。老师还借着洞壁上的岩石纹理，给我们讲了千灵山这里的石灰岩是怎么经过千万年的流水侵蚀变成现在的样子，原来我们脚下踩的、手里摸的石头，都藏着这么久的故事。下山的时候腿已经酸得打颤，但和同学互相扶着一步步往下走，风从耳边吹过的时候，突然觉得这就是小学最后一次秋游最棒的回忆。

张伯源，Class 6-1

今天社会实践，我们去了千灵山！导游说，岩石就像是地球的皮肤和骨骼，里面藏着好多故事，记录着地球一点点变化的过程。听完我觉得大自然也太神奇啦！

  李雨芙，Class 4-1

今天研学，我认识了地层！地质大剖面就像一块切开的蛋糕。导游老师拿出岩石，耐心地给我们讲解。原来一层层叠起来的岩石就是地层，地层越往下越古老，越往上越年轻。走进大自然学习知识，真的太有趣啦！

 赵又平，Class 4-1

我们今天的研学可太有意思啦！导游老师给我们介绍了会变魔术的石头 —— 石灰。从开采、煅烧，再到加水，每一步都有讲究，一点都不能弄错。古时候人们的工具特别简陋，干活特别辛苦。后来慢慢发展，还用上了轨道，真厉害！我觉得我们的祖先太了不起了。

  李赫宸，Class 4-1

今天研学，我亲手体验了挖化石！我挖到了三叶虫，还有菊石，开心极了！这些地球的远古居民，就这样真实地出现在我眼前。我长大以后想当一名考古学家，继续去大山里寻找更多的 “远古居民”，探究它们以前是怎样生活的。
