Introductory Activity

Station 1 – Biology mind map Take out your science textbook and look for the

biology unit. As a group, list the main topics in the unit along with at least 10 key words for each topic.

Using chart paper and markers, create a graphic organizer (e.g. Venn Diagram, mind map, flow chart etc.) to present these ideas in an organized manner.

Station 2 – Biological Hierarchy (instructions on envelope)

Station 3 – Sorting Prokaryote & Eukaryote (instructions on envelope)

Levels of Biological Organization

A hierarchy shows more complex levels at the top with simpler levels below

Biological hierarchy can be divided into 12 levels of organization, 6 of which are specific for animal structure

Place the following 12 levels into a hierarchy:
