Kimchi is a spicy pickled cabbage dish eaten in Korea and China. Using Kimchi as a teaching vehicle, this lesson is about how plants absorb and lose water. The lesson has three main learning/teaching goals. The first main learning goal is to understand that plants absorb and lose water through cells. The second is to learn how to observe the plasmolysis of plants. The third one is to understand the principle of osmosis in plant cells. As a prerequisite to this lesson, students should know about the structure of plants and the concept of diffusion. This lesson is about 40 minutes. The instructions for all the experiments in this lesson can be downloaded off the BLOSSOMS webpage.

这节课是关于植物细胞吸水失水的原理,主要学习目标有三点:一是了解植物吸水和失水是在植物细胞层次上完成的。二是学会观察植物细胞质壁分离与复原的方法。三是了解植物细胞发生渗透作用的原理。学生学习这节课的前提知识是了解细胞的结构与功能,植物体的结构层次以及物质扩散的原理。这节课的时间有40分钟,课时为1课时。由于这节课有三个实验,具体的实验器材材料以及实验步骤可以在这节课的补充材料里下载

I liked STEM subjects when I was in the middle school, especially math. However I chose biology as my major when I went to college. I’ve taught middle school biology for 20 years and worked as a class adviser for 14 years. So I have rich experience in class management and student development.

我在中学是喜欢理科,特别是数学,读大学时我选择了生物学。从事初中生物教学已经有20年,班主任工作有14年,在班级管理和学生的培养上我很有经验和优势。

This resource provides a comprehensive overview of Diffusion and Osmosis.
