After the zoology teaching in the second year ended, we organized students to visit the Nature Museum to achieve a comprehensive review of zoology knowledge. Based on the specimens displayed in the museum, combined with the teaching content of zoology, we focused on vertebrates, focusing on animal evolution, adaptation of animal morphology and living environment, and the role of animals in maintaining the relative balance of ecosystems. Visit the homework assignments and ask the students to complete the homework while visiting. The test has achieved good teaching results. (Visit time is 2 hours). The questions we drafted were as follows: 1. After mid-Devonian period. Evolution of fish evolved into amphibians. At that time, the climate change was __. 2. At the end of the Mesozoic, the climate change was __, and reptiles could not adapt, and they died in large numbers, but they were bred by ancient reptiles.
