Enrichment Activity 1: Arrange the steps in using the Compound Microscope. USE NUMBERS 1–10 (where no. 1 will be the first step). Write your answer on a separate sheet of paper. 1. Look through the eyepiece and move the focus knob until the image comes into focus.
2. When finished, lower the stage, click the low power lens into position and remove the slide.
3. Look at the objective lens and the stage from the side and turn the focus knob so the stage moves upward. Move it up as far as it will go without letting the objective touch the coverslip.
4. Use the focus knob to place the sample into focus and readjust the condenser and light intensity for the clearest image (with low power objectives you might need to reduce the light intensity or shut the condenser).
5. Turn the revolving turret so that the lowest power objective lens (eg. 4x) is clicked into position.
6. When you have a clear image of your sample with the lowest power objective, you can change to the next objective lenses.
