Two students were working together on a laboratory assignment to view microscopic pond organisms
with a compound light microscope. The students
used an eye dropper to obtain a sample of pond
water and placed the sample on a clean slide. They
put the slide on the stage of the microscope and
observed the sample first under low power and then
under high power to see the organisms. Using one or

students' procedures.
