Tomorrow, in order to observe cells, we will be doing our first microscope lab!Before we can do that, you must learn the different parts of the microscope in order to properly use one.

Tape the labeled microscope on to page ___ of your journals.

• In groups, complete the “Using a Microscope” activity• Take turns doing the following jobs:

• Reader: Will read directions #1-17 out loud for the Microscopist• Microscopist: Will follow directions step by step• Observer: Will put “check marks” or “x”s beside each step on the Microscopist’s lab sheet, based on how they followed each direction• Grader: Will fill out the “Task Assessment” based on how well the Microscopist’s did overall

CORK CELL LAB – page _____

Purpose: Observe cork cells underneath a microscope.

Pre-Lab questions:1. What does the cork look like?2. Is the cork living or non-living?3. Is the cork unicellular or multicellular?

Cells and Microscopes January 29-30, 2014

Ms. SmithMrs. MaloneMs. Cedillo

Draw the following in your journal. Create “prediction” drawings showing what you think the cork will look like under the microscope at 40 and 100 times magnification. You will fill in the actual drawings when you use the microscope.

Predictions: Actual:

4X 10X 4X 10X

CORK CELL LAB – Conclusion Questions

1. Did the cork look how you predicted? Why or why not?2. Is the cork prokaryotic or eukaryotic? How do you know?

If you finish the conclusion questions above, ask your teacher for enrichment microscope activities!
