7. Special Notes • To Teacher: The students will decide on their own to implement the plans, along with the specific procedures for building the model. The students will then exchange procedures/plans with another group (two students maximum). • Allow the students have total creativity for choosing the materials they wish to use. • Evaluation-set microscopes up prior to lab, cover the specimen names. • Prior learning should be: organelles and parts of the cell, and differences between plant and animal cells.

8. Special Notes cont. • Allow 60 minutes for the students to complete the 3-D models. • Allow 30 minutes for evaluation lab. • Give students the blank Venn-diagram worksheet. • Pictures are from: www.campbellbiology.comhttp://micro.magnet.fsu.edu/index.html

9. Discovering the Cell

10. Engagement • Why is magnification important to science? (OBJECTIVES) • Explore and compare the organelles of different cell types. (Biology Tennessee State Standards 1.0 Cells) • Make plans and procedures for building models of two types of cells. • Build a 3-D model of a typical cell. (1.0 Cells) • Classify an unknown cell (prokaryotic/eukaryotic) using a compound microscope. (1.0 Cells)

11. Exploration • 1) Make plans and procedures using any art materials supplied for a 3-D Model of both the prokaryotic and eukaryotic cells that another group can easily follow. • 2) Exchange plans with another group. • 3) Follow the plans and build both models.

12. Explanation • What makes human beings get sick?

13. Prokaryotic Cells • A unicellular organism that lacks a nucleus and membrane-bound organelles. (p. 72)

14. Prokaryotic Cells

15. Eukaryotic Cells • A cell that contains a nucleus and membrane-bound organelles. (p. 72)

16. Eukaryotic Cells

17. Size Comparison

18. Extension or Elaboration • Use the Venn-Diagram to discover how the prokaryotic and the eukaryotic cells are different and alike. Prokaryotic Same Eukaryotic

19. Evaluation • Number your paper 1-10. • Go to the microscopes and decide whether the slides contain prokaryotic cells or eukaryotic cells. Record your answer on your paper. • 5 Point Bonus: For the eukaryotic cells, list whether they are plant or animal cell.

20. End Notes • In your science journal, make a KWL chart like the one below. Fill in the following information.
