1, organize students to collect and make specimens. This item is organized according to the requirements of the textbook experiment class. When I was just in junior high school, I organized students to make specimens for all experimental classes in senior one and senior two, and sometimes they would be graded and properly included in the final grade of the semester. Later, he taught senior high school classes and guided students to make specimens with the teachers of science group, with the aim of stimulating students' interest in learning biology classes and improving their skills in making specimens. Over the years, we have made a large number of specimens. Many specimens have been improved and innovated, and many have been rewarded and popularized. For example, 1994, The Rapid Making of Plant Color-Preserving Specimens by Three Students won the third prize of the 7th National Youth Invention and the second prize of Hainan Province. Another two won the second and third prizes for provincial inventions. 1995 1 one piece won the third prize of provincial hundred biological activities, and 1996 two pieces won the third prize of provincial invention and creation. Some of them are kept in the biology laboratory as teaching AIDS. These specimens were praised by visiting colleagues from various schools, leaders of ministries and agencies, and director of the Youth Science and Technology Activities Office of China Association for Science and Technology. The production methods have been published and popularized by Biology Journal, Biology Experimental Teaching and Instruments, Biology Journal, etc. The editorial board of China Library also plans to select these methods and experiences into the book.
2 organize students to carry out activities to cultivate flowers and publicize flowers and trees. They have carried out cuttage propagation of red mulberry, hibiscus mutabilis and other flowers in the biological park, and also organized students to raise potted flowers at home, and then brought them to the school for evaluation and reward. Through the activities, a number of flowers were cultivated, the students' view of loving labor was cultivated, and some flower breeding techniques were learned.
3. Guide students to carry out scientific experiments. We have carried out the feeding experiment of paramecium and fruit fly, and also carried out the scientific experiment of carrying tomato seeds by satellite. Through experiments, students have mastered and understood some methods of scientific experiments and achieved good results. For example, the scientific experiment of carrying tomato seeds by satellite won the first prize in China and the first prize in Hainan Province. Recently, I also accepted the task assigned by the Chinese Academy of Sciences and organized students to carry out the experiment of "carrying Chinese cabbage seeds by satellite", which was successful and won the first prize in the province and the first prize in the country.
4. Organize students to go out for inspection and visit. Methods: Elaborate the activity plan; (2) According to the experimental situation of the school, the activity plan should be designed reasonably. If our No.1 Middle School is an urban school, we can't design experiments on rubber planting and rice planting, but we can only do some experiments with small land area. (3) guide the activities carefully, let students operate freely, do not do everything instead, seek truth from facts, and do not resort to deceit. (4) Carefully check the effect of the activities, some of which can be graded and registered, and sometimes even rewarded to arouse students' enthusiasm.
