5
Cell Counting:
These slides explain how to count cells from a random sampling of a slide, and how these values can be used to compare samples.

6
Volume Density of Cells:
This PowerPoint describes how to take a volume density measurement from a random sample of a slide. Slides of blood samples are used. Two volume density measurements are compared.

7
Volume Density of Tissues (Testicular):
These slides describe how a volume density measurement is taken from a tissue sample instead of a blood sample. These slides describe which types of cells are found in testicular tissue.
OR

8
Percentage of White Blood Cells:
These slides describe how to mathematically determine the percentage of each type of white blood cell that is present within a blood sample. Example images to assist with the types of white blood cell are also included.

9
Diameter of Cells - White Blood Cells:
This PowerPoint explains how to measure the average sizes of white blood cells found in a healthy blood sample. Instructions on how to use the “ruler” tool of the website are also included. The average sizes for each type of white blood cells are compared.

10
Diameter of Cells – Red Blood Cells and Reticulocytes:
This PowerPoint describes how to measure and compare the average size of red blood cells and immature reticulocytes from a healthy blood sample. Instructions on how to use the “ruler” tool of the website are also included.
OR

11
Organelle Volume Density (electron microscopy):
These slides describe how an organelle volume density measurement is taken from an electron microscopy image. The values are calculated, and the densities of various organelles are compared. Additional electron microscopy images are included for practice.

12
Comparison of Plant and Animal Cells:
This PowerPoint explains how to measure the volume density, or nucleus:cytoplasm ratio of cells. These slides also describe and compare the various shapes of animal cells.
OR

13
Examining Plant and Animal Cells:
This presentation examines differences in plant and animal cell organelles, structure, and function, and illustrates vivid microscopic images of the organelles of plant cells and animal cells (including blood, muscle, and epithelium), and also discusses the interaction of cell structure and function.

The PEER Program is composed of three grants entitled "GK-12 Fellows Integrate Science/Math in Rural Middle Schools", "Integrating Environmental Health Science in Rural Schools," and a Science Education Partnership Award (SEPA) entitled "Science Promotion in Rural Middle Schools".

Major funding for the PEER Program is provided by John Deere,
the
National Science Foundation, the
National Institute of Environmental Health Sciences
and the Office of Research Infrastructure Programs (ORIP) at the National Institutes of Health (NIH).
