Leaf Structure Under the Microscope
Place the cellotape on a clean microscope slide and observe under medium and then high power settings. The students will be asked to compare the number of stomata on both the top and bottom of the leaf.... Microscopes have given biologists a lot of help in viewing organisms too small to be seen by the naked eye. These optical instruments have allowed them to make observations and studies based on what they see through the microscope lens.

What kind of microscope did you get ? Sounds like you are zooming in too far, you just need to wait till flower to see what color the trichs are, I think I was able to do it with a 10x magnifying glass.... when collecting specimens they will only need to gather enough to look at under a microscope and not to take more than they need.

Instruct students to meet back at the Visitor Center when the whistle blows
When viewed with a microscope, they often look like coffee beans. There are more than 32 stomata in the image of the Western Sword Fern leaf, to the right. Carbon dioxide (CO?), oxygen (O?) and water (H?0) commonly move in or out via the stomata....

(Look closely, you will be amazed how many you can find). Get clear plastic "bug boxes" and trap live insects so you can watch them move about under your microscope.

How To Look At Leaves Under A Microscope
Back at the lab, carefully tear the leaf to make a ragged edge to inspect under the microscope. The best tears show a clear layer of epidermis, a partial layer of the inner portion of the leaf, and an intact section of leaf.
- If you look at a feather under a microscope, you see the main stem, with barbs coming out to the left and right, and from these you have left-and right-handed barbules. In a Pap smear, cells scraped from the cervix are analyzed under a microscope for physical abnormalities.

- Once you view the insects under a dissecting microscope, you may wish to view more details of a specific part of the insect. If this is the case, you will need to dissect the insect and prepare a slide.
- Those dyes, which sat for decades on the plants, now make for arty images under a microscope. Other photos on the Flickr page include microscopic images of crystals and oil.
