Small group – Competition REWARD, and write in your notebook.
Review – Quiz material:
1) Living things are made up of cells. Cells are organized at different levels to form very complex living organisms like your body. Each level has a specific role or job to perform. List these levels in the correct order of organization from the simplest to the most complex?
2) All living things, plant or animal, have
one thing in common. _____?
3) All of the following are characteristics
of both living organisms and cells
A- remove waste from themselves
B- rely on chemicals for
C- grow and die
D- extract energy from food
4) Ashley saw a cell under a
microscope and drew what she saw.
This cell is classified as —
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…
Small Group Activity- Review
Textbook p. 853 “Reference Handbook C”; Care and Use of a Microscope. And Handout to place in your notebook.
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.
