What children learn in Level 31
- Welcome to Cell City! Every living thing is built from cells, the tiny units of life.
- Most cells are far too small to see. In the 1660s, Robert Hooke looked at cork through a microscope and saw tiny boxes. The name cells stuck.
- Here's the evidence. A leaf looks smooth, until you magnify it. Then you see it's made of cells.
Georgia Standards of Excellence in Science:
- S5L3.a — Gather evidence by utilizing technology tools to support a claim that plants and animals are comprised of cells too small to be seen without magnification.
