Note: Using an eyedropper with just the right pressure to get a desired amount of liquid onto a slide can be harder than it looks. Take out a clean slide and practice squeezing a drop of water onto the slide until you feel comfortable that you can control the size of the drop that you’re squeezing out. 4. Observe the life cycle of the shrimp as they

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.

Scrape off some shavings and make a smear as you did with the potato. Compare how the corn is different from potato. Create smears of other foods such as apples, bananas, peach- es, and pineapples. You will observe that these items have membranes rather than starch. To save your slides, put gum media on a clean dr

Be very careful and try not to touch the specimen. Allow the specimen to air dry for sev- eral minutes. Some of the specimen will be flushed away, but enough will remain on the slide to make good observations. To save your slides, follow the pro- cedure described previously.
