Biological Practical Activities
Dear classmates, have you ever wondered about putting a small piece of nature into a bottle? Not only is this a wonderful exploration of science, but also an excellent way to experience the cycle of life! Today, let's take you all to enjoy the wonderful miniature world ecosystem bottles created by our classmates! What is an ecological bottle? An ecological bottle is a glass container that simulates a natural ecosystem, which forms a self-sufficient miniature world through the collaborative efforts of plants, microorganisms and small animals. Thus, not only is it a vivid practical experience of biology lessons, but also a 'living textbook' for observing the flow of energy and the cycling of matter!
To begin with, Zheng Langyi from Class 807 was quoted as saying, 'during the process of observing the ecological bottle, I watched the small fish swimming among the water plants, and saw the water quality remaining clear day by day, which turns out that the 'ecological balance' mentioned in the textbooks was truly presented before my eyes. Thank you, teachers, for introducing us to the wonderful world of biology. In the meantime, thank you, classmates, for the wonderful time we spent exploring together!'
In addition, Fan Zixin from Class 804 was quoted as saying, 'this activity has made me realize that biology is not just dry knowledge points, but rather a vibrant and interconnected network of life. Now, every time I see the ecological bottle, I feel as if I have understood a piece of the 'secret conversation' of nature, which turns out that the mysteries of nature are hidden in these small interactions.'
Last but not the least, Lei Lingna from Class 806 replied, 'through this activity of making an ecological bottle, I for the first time truly experienced the meaning of 'balance': If you put in just one less water plant, the water quality might become murky; Likewise, if you feed the fish a little more food, the little fish will lose their vitality, which was not just a practical experience, but also made me realize that whether it's a small ecological bottle or the entire Earth on which we depend, every living being and every element are all closely interconnected.'
To summarize, congratulations to all the students who participated in the activity! Your creativity and scientific spirit are truly admirable! More remarkably, each ecological bottle is a unique natural miniature, allowing us to continue exploring the mysteries of life!
