Question

Make accurate illustrations of objects seen through a microscope. INTRODUCTION Making precise observations is essential in science. Often scientists use instruments that extencd their senses. Microscopes are such instruments. In today's lab students will learn proper usage of the compound light microscope and binocular dissecting microscope. Correctly match the letters on the illustration to the microscope structures listed below. 1. arm 2. base 3, coarse-focus adjustment knob 4. condenser (knob for raising and lowering B. condenser is not shown) 5. diopter adjustment 6. fine-focus adjustment knob 7. iris diaphragm ring 8. light 9. light switch ?10.mechanical stage control knobs 11.mechanical stage mechanism 12.nosepiece 13.objective 14. ocular 15.rheostat 16.stage Laboratory 3: Microscopes

Explanation / Answer

1.) P (ARM); it provides support

2) J (BASE); it is the bottom part

3) M (COARSE FOCUS ADJUSTMENT); it moves the slide so that specimen could be focused

4) H (CONDENSOR) ; its main function is to focus light from source on the specimen.

5) B (DIOPTER) ; it is in the occular.It helps is compensating the differences between eyes.

6) L

7) D (IRIS) ; it usually changes the intensity of light

8) I (LIGHT) it is a light source

9) O

10) K

11) G

12) C (NOSE PIECE) ; its function is to hold the objective lens.

13) E (OBJECTIVE ) ; The lens which is near to the specimen.

14) A ( OCCULAR) ; it is also called eye piece through which we see into the microscope.

15)N (rheostat) ;it changes the current which reaches to the light source

16.) F (STAGE) ; The place where slides are kept.
