The student shall demonstrate their ability to use the microscope by correctly determining the size of a number of organisms on prepared slides or living cultures.
Size is as important in the micro world as it is on our own visible world.
Use the above information to determine an organism's size. Draw an organism on your overhead and have the students help you determine its size. You may need to do this with several imaginary organisms. Make sure everyone is on the lowest power and that they are thinking in terms of proportion. This lesson is deceptively difficult for many students.
