教學目的 • Primary - To understand the concept of characteristics or traits and how a single species can exhibit distinct differences over the course of history through human selection. • To understand structure and function of plant parts. • To understand the basic needs of plants and their care. • To foster an appreciation of food sources. • To encourage outdoor physical activity. • To encourage healthy eating behaviors.
教學內容 Provide students with a selection of seedlings of Brassica oleracea (Cabbage “family”, which includes broccoli, cauliflower, cabbage, collards, kale, and brussel sprouts) to examine. Include color or textural variations when possible (red & green or savoyed cabbage, purple & white kohlrabi, kale of different colors or textures). Without naming the seedlings, ask students to describe similarities and differences, and try to guess what they are. Many of the seedlings may look identical until they start to distinguish themselves nearing maturity. Introduce the cabbage “family”, and ask students to name some of the vegetables in the family. Explain to students that the different vegetables are actually the same species, and discuss how the different characteristics or traits have been selected over the course of human history. Try to lead students to come up with other examples in the plant or animal kingdom (good examples are domestic animals like dogs, cats, cows, horses, etc.) After discussion, students can plant and tend for the seedlings and as they develop, see the differences that emerge. Final steps: harvest & eat!
