Further Experiments: Try out the above proce-

dure with other salts such as Epsom and

Rochelle. Sugar will also crystallize, but you will

need to let it dry overnight for the crystals to

form.

Preparing a Mount

Dip your spatula (C, Fig. 1) in some clean water

and make a smear across a clean slide. Use

your tweezers (A, Fig. 1) to place a portion of an

insect—a wing, a leg, or an antenna—on the

slide. Attach a cover slip (

I, Fig. 1) over the spec-

imen and place the slide on the microscope

stage.

Obtain a piece of hair from your head or from

your pet and place it on a wet slide. Try this

again with more than one type of hair on a slide

and compare how they differ. Also try a piece of

fern (or other plant) and pollen and compare

them as well.

To save your slides, put gum media on a clean

dry slide and then position your specimen in the

media. Place a cover slip over the media and

attach a label.

Creating Smears

Using your scalpel (B, Fig. 1), gently scrape off

small shavings from the surface of a freshly cut

potato.

Smear the shavings onto a clean slide (see

Figs.

6 and 7). Clean the scalpel by swishing it in the

flush water. Draw up some water using your eye-

dropper from the cup labeled clean and put one

drop onto the slide. Attach a cover slip to the
