显微镜下的细胞
Cells Under the Microscope
理解所有生物体都由细胞组成，并能使用光学显微镜观察、解读和记录细胞结构。
Understand that all living organisms are made of cells and use a light microscope to observe, interpret, and record cell structure
学习证据 / Evidence
- 说出所有生物都由细胞构成
- 在显微镜下制作或观察细胞装片（如洋葱表皮、口腔上皮细胞）
- 绘制观察到的细胞示意图并标注各部分
- 能在显微镜图像中识别出细胞核、细胞质和细胞膜
- States that all living things are made of cells
- Prepares or examines a slide of cells (e.g. onion skin, cheek cells) under a microscope
- Draws and labels a diagram of cells observed
- Identifies nucleus, cytoplasm, and cell membrane in a microscope image
评估问题 / Assessment
如果{{name}}制作了一片洋葱表皮装片，并用学校显微镜观察，他们能否辨认出所看到的结构，并解释所有生物都是由这些微小单位构成的？
If {{name}} prepared a slide of onion skin and looked at it through a school microscope, could they identify what they were seeing and explain that all living things are made of these tiny units?
