Grade 11 Biology: Microscope Slide Observation

Read each question carefully and provide your answers in the spaces provided. This worksheet will assess your understanding of microscope parts, slide preparation, and observation techniques.

1. Which part of the microscope controls the amount of light passing through the specimen?

2. What is the total magnification if the eyepiece is 10x and the objective lens is 40x?

1. The   is used for initial focusing under low power.

2. When moving from a lower power objective to a higher power objective, the specimen should remain mostly in focus due to the microscope being  .

3. The circular area seen through the eyepiece is called the  .

4. To calculate the total magnification, you multiply the eyepiece magnification by the   magnification.

1. It is acceptable to use lens paper to clean the stage of the microscope.

2. When preparing a wet mount slide, always add the coverslip at an angle to prevent air bubbles.

1. Briefly explain the proper procedure for bringing a specimen into focus under a compound microscope, starting from the lowest power objective.

2. Describe two common mistakes made during wet mount slide preparation and how to avoid them.

Match each microscope part on the left with its correct function on the right.
