Real World Lab-
Use what you have learned about microscopes to-
1. View and sketch the Letter "e" slide at all three levels of magnification-
- be sure to label your sketches according to total magnification
- take an image of your sketches and post it here:
2. View the Colored Threads Slide:
- Describe how/why turning the fine adjustment allows you to observe the threads at different depths.
(Think about how the stage moves up and down into different planes of view as you focus the slide)
Pond Organisms- (Single-celled Eukaryotes)
3. Look at a drop of the pond organism Paramecium using the well slides.
- What are the protrusions coming out of the paramecium?
Add some yeast stained with Congo Red solution- and observe.
- Describe how the Paramecium eats the yeast cells
