7. Evidence Card Sort
You and your partners will sort the evidence cards based on the three components of Cell Theory:
All living things are made up of cells
Cells are the basic unit of life
Cells come from pre-existing cells

8. Explain What evidence supports each component of the cell theory?
In 1663, after Robert Hooke looked at the cork cells, was there enough evidence to support the cell theory? Why or why not?
How did Robert Hooke’s observation turn into a scientific theory?
Is the cell theory a strong theory? Why or why not?
What evidence could make the cell theory stronger?
What evidence would discount the cell theory?
What is the significance of the microscope in providing evidence for the cell theory?
What makes something a scientific theory?
How is a scientific theory different from a non-theory?

9. One Stay, others stray
The person with the next closest birthday stays, you are the spokesperson for the group. You will stay with the cards to answer questions.
Other members of group rotate to each of the groups.
Look over the organization of the evidence.
Ask the spokesperson to clarify any questions that you might have about the choices made for placement of the evidence.
Continue until you have returned to your original location.
