Some More Ideas for Observation

Children:

get adult's permission before trying any experiments!

1. Crystals: Place a few grains of dry salt or sugar on a slide to observe. Mix

salt with a spoonful of warm water in the test tube and then use the plastic

dropper to place a couple drops on a slide. Let it dry and observe the

re-crystallized salt/sugar.

2. Shake some grains of pollen from a flower onto a blank slide.

3. Hairs, including pet hair, or pieces of feathers, can be observed. Try

comparing hairs from various animals. You can use a small piece of tape at

each end of the hair to hold it on the slide.

4. Observe fibers in different kinds of paper, printing from a newspaper or

typewriter. Look at the color in comics. Compare threads or fibers from

different types of fabric.

5. Stagnant water from a pond will contain live organisms. Place a drop into the

well of a concavity slide for observation.

6. Many specimens may look transparent under the microscope. It's common to

stain them to make the cells show up better. Iodine is a common stain. Or try

soaking your tissue specimens in a solution of ordinary food color

(included—add water to thin) for a couple of minutes to stain them. Use the

tweezers to pick up the "stained" specimen. Allow the "stained" specimen to

dry before using glue to mount it.

anything else it touches, not just your specimen, so be careful with furniture

and clothing.

Caution:

Remember the stain will color

Magnifications

Total magnification is calculated by multiplying the eyepiece magnification

(always 10X) by the objective lens.

Note: the 40X lens is not suitable for use with the upper lighting due to the

focusing distance required. The lens must be too close to the specimen and

does not allow enough light to reach the specimen.
