Extracurricular materials

1. Fabre: (1823-1915) a famous French scientist and popular science writer. He grew up in poverty and was admitted to a normal school at the age of 15. After graduation, he taught mathematics in a junior high school. Once, I took my students to an outdoor geometry class and suddenly discovered peaks and honeycombs on the rocks. From then on, my "worm heart" glowed. He spent a month's salary to buy a book on entomology, determined to be a person who writes the history of insects. He spent his whole life going deep into the world of insects, observing and experimenting on insects in their natural environment, truly recording their instincts and habits, and wrote the 10-volume "Insect Diary".

2. How do animals identify directions and know routes? Scientists have used animal navigation experiments on bees and pigeons to initially reveal the secrets of the navigation of these two animals. The famous Nobel Prize winner and Austrian biologist Frisch used a series of experiments to measure the basic navigation ability of bees in the 1940s, proving that bees usually use the sun as a compass to navigate. Point out that bees use the sun as a reference point and use the "dance" to tell other bees how to reach the source of flowers they find.
