DIY: Slides

A great project for kids of any age is making a variety of microscope slides to view under your high power microscope.

When making temporary slides, the supplies needed are very basic:
1. blank slide
2. cover slip In order to make your slide, simply place the specimen on the slide, apply the cover slip so it lays flat, and view under the microscope.
3. When finished viewing, wash the slide in warm soapy water. The cover slip is quite thin so be careful that you don't break it during cleaning.

Creating permanent slides involves sealing your specimen within the slide so it lasts, and then labeling the slide so that years from now you remember what the sample was. You may also want to stain the slide, if so, this page offers great information on staining microscope slides.
1. Prepare the slide just as you would when making temporary slides.
2. When applying the cover slip, you will want to coat the very outer edges of the cover slip with a thin layer of clear nail polish or cement in order to permanently seal the cover slip to the slide.
3. Make sure your layer of adhesive is not too thick, as this will cause problems with not being able to focus properly on your specimen.

Fun slide making ideas!
1. Cheek cells from inside your mouth (use a Q-tip to scrape the inside of your mouth).
2. Pond water, or water from a muddy puddle.
3. Fine sand particles, sugar, salt, baking soda, a vitamin C tablet - any fine powdery substance. (If you have a polarizing filter - use it when viewing these items as well!)
4. Fabric fibers or strings. Cotton - a thin strand pulled off a cotton ball.
5. Soil from the back yard. A blade of grass or a thin section of a flower.
