Ms. Yun is not teaching any biology classes right now, but she has taught Biology 11 and a little bit of Biology 12. These courses are now called Life Sciences 11 and Anatomy and Physiology 12. She also teaches Science 8 and Science 9, which both have a biology component, and she has taught biology in Science 10. Biology 11, now called Life Sciences 11, focuses on evolution, animals, plants, and how organisms adapt to their environments. Students go through many different phyla, classes, and families of animals and plants. Biology 12, or Anatomy and Physiology 12, is focused on human anatomy and the different body systems. Students take her classes hopefully because they have an interest in biology. Some take them because they want to go into the sciences. Biology is also very tangible (students encounter living things every day, so it connects directly to life). Students enjoy the cool videos that show animals and organisms not usually seen in everyday life. Lab work and dissections are highlights (they are very engaging). There are many careers related to biology. Students can go into research, microbiology labs, or healthcare careers like nursing and medicine. Dissections happen in several grades. In Life Sciences 11, students have dissected squid, sea stars, rats, frogs, and earthworms. Ms. Yun uses a variety of teaching methods (videos, guided notes, diagrams, readings, textbooks, and real-world examples). She also makes lessons interactive with questions, discussions, projects, and labs. Variety is key. Assessment includes quizzes and tests with multiple-choice and short-answer questions, as well as projects and labs. Some students show their learning better through hands-on work like dissections, where they can identify parts and explain systems. Learning biology helps students appreciate the world and understand how living things and ecosystems interact. It connects to health, nutrition, and medicine. Students often find it difficult to differentiate between very small concepts (like genetics and chromosomes) and very large concepts (like evolutionary processes). Some students also find memorization challenging (especially in anatomy, which includes many terms). Ideally, however, learning is not just about memorization but understanding how everything works together. Ms. Yun believes biology is extremely important. There are living things all around (including humans), so understanding biology helps students understand life.
