Title:
Microscope Labs
Purpose:
- To learn to use
a microscope
- To observe, draw,
and describe objects seen under a microscope
Materials:
- Microscope
- Prepared Slides
(letter "e", cork, threads, fibers, prokaryotic and eukaryotic cells)
- Human hair (yours)
- Mammal hair
- Onion skin: yellow,
white, & purple
- Elodea leaves
Slides & Cover Slips
- Potatoes, Tomatoes,
Green Peppers, & Apples
- Pond Water
- Toothpick
- Iodine Methylene
Blue
Procedure:
- Observe, Draw,
& Describe all prepared slides at low and high power
- Make wet mount
of human and mammal hair. Observe, draw, and describe normal, chemically
treated, and mammal hair samples. Also, observe, draw, and describe
split ends
- Make wet mounts
of, onion, Elodea, potato, tomato, apple, green pepper…observe,
draw, & describe at low and high power & label cell
membrane, nucleus, cytoplasm.
- Make wet mount
of cheek cell using methylene blue….. observe, draw, & describe
at low and high power & label cell membrane, nucleus, cytoplasm.
- Make wet mount
of "pond water"…observe, draw, & describe…..
Results:
(Observations
and data~~~data charts and graphs and calculations where appropriate.Organization
is necessary)
- For this lab: Labeled
drawings and descriptions
Discussion:
- Summarize what
you did.
- Comment on what
happens when you move the letter "e" in different directions.
- Comment on differences
in view between low and high power.
- Describe differences
and similarities between animal and plant cells and prokaryotic and
eukaryotic cells….differences and similarities that you observed!
Conclusion:
(A one sentence
testable statement that follows from your results, what you did, what
you observed)
Reflection:
(A personal
statement about the activity, whether it relates to "real life," whether
you liked it, suggested improvements
