Calculate the field of view diameter of a microscope under medium or high power.
Outline how to estimate the size of a sample in the microscope field of view.
Demonstrate how to focus the microscope on a sample.
1.1.S2 Drawing of cell structures as seen with the light microscope.
Demonstrate how to draw cell structures seen with a microscope using sharp, carefully joined lines and straight edge lines for labels.
1.1.S3 Calculation of the magnification of drawings and the actual size of structures and ultrastructures shown in drawings or micrographs.
Define micrograph.
State why the magnification of a drawing or micrograph is not the same as the magnification of the microscope.
Use a formula to calculate the magnification of a micrograph or drawing.
If given the magnification of a micrograph or drawing, use a formula to calculate the actual size of a specimen.
1.1.NOS1 Looking for trends and discrepancies- although most organisms conform to cell theory, there are exceptions.
Define "trend" and explain why trends are useful in scientific study.
Define "discrepancy" and explain why discrepancies are useful in scientific study.
List features that would be considered a “trend” related to the cell theory.
1.1.NOS2 Ethical implications of research- research involving stem cells is growing in importance and raises ethical issues.
