To Begin…Over the next few days, our class will be completing a descriptive investigation to learn more about the idea that all living organisms are composed of cells.You will be using the microscope to observe a variety of organisms. Asyou observe each, you will make detailed drawings.
Tape the handout “Scientific Processes: for Experimental Investigations” in your notebook. Copy this Format…
All Living Organisms are Composed of Cells
1)Problem: What did each organism have in common with the others? Were all of the cells observed the same shape? Why do cells have different shapes?
2) Hypothesis: If cells are different, then I will see that evidence in my drawings using labels. I will also observe what is the same and make notes.
3) Procedure: Following proper use procedures for a microscope and glass and electrical safety rules. Record additional statements and make detailed drawings in my science notebook. Each drawing will be labeled with the magnification used and the identification of the specimen. (color, shapes)
4) Materials: microscope, prepared slides from a variety of organisms
Slide #1- Human Epithelial (blue stain), focus x100,
You See: course x10
You draw and label:
Continue to record and draw each slide with labels.
6) Results: My data/facts show…
7) Conclusions: To answer the questions:
What each organism slide has in common is…
Are the cells the same shape…
Why they are different shapes…
8) Applications: I conclude with my data and facts that…

By the end of this lesson, you will be asked to properly focus a microscope on a specimen.
Small group Investigative activity: 2-3 students per group, view slides and take notebook data. Remind students they are responsible for damages.
