Title: Plant Cells / "Looking at Elodea" WS
3m
One Student - Bring a slide up and tweezers to the table and prepare a wet mount of Elodea leaf.
Slide, Elodea leaf (correct side up), Drop of Pond Water, Cover Slip.
(5 Minutes) to prepare slide.
Set your total power to 100x (10x eyepiece * 10x objective lens = 100x)Limit your microscope time to 1 minute (7 Minutes) focus up and down through the leaf. If you are not looking at the slide...
*Sit down *Record your observations for "Part 1: Elodea at 100x."
Guiding questions: What do you see when you look at the Elodea?What did you notice when focus up and down through the leaf?
