Science Trimester Part 1!!!

Front 1

how do you hold a microscope?

Back 1

one hand on the arm, one supporting the base

Front 2

how do things appear on a microscope?

Back 2

upside down and backwards

Front 3

how to make a wet mount:

Back 3

place 2-3 drops of water on a clean slide. then place the specimen on top. hold the cover slip perpendicular to the slide at the edge of the water and lower slowly to reduce air bubbles

Front 4

how to find total magnification:

Back 4

multiply the power of the ocular lens but the power of the objective lens

Front 5

resolution

Back 5

the capacity to show two separate points that are close together

Front 6

magnification

Back 6

the enlargement of an image brought about by the lenses

Front 7

magnification power

Back 7

how much larger the image appears through the lenses

Front 8

2 parts that adjust resolution:

Back 8

coarse adjustment and fine adjustment

the _________ magnifies the image of the specimen

Front 20

function of the coarse adjustment

Back 20

the _________ moves the body tube up and down to bring the object into focus

Front 21

function of the fine adjustment

Back 21

the _________ moves the body tube up and down veryyy slightly to bring the object into focus

Front 22

function of the inclination joint

Back 22

the _________ adjusts the angle of the microscope

Front 23

Where is the inclination joint located on our microscope?

Back 23

TRICK QUESTION!!! ours doesn't have one =P

Front 24

3 things that happen to the specimen when looked at through the microscope:

Back 24

upside down, flipped, and gets bigger
