Microscope: Fairy Wings


When deciding to buy a family-friendly microscope, I looked no further than Tinkerlab.
Several of their activities feature 'My First Lab Duo Microscope'

I remember having a microscope as a child and loving how grown-up I felt, playing scientist!

We purchased this one, as well as a separate set of prepared slides for viewing.
However, there is no lack of objects to look at under a scope, from around the house and community.  http://www.examiner.com/article/50-things-to-look-at-under-a-microscope
We discussed how many scientists use microscopes and what kinds of things that are commonly examined in the lab; blood, in particular was a specimen that O was eager for me to provide!

Before we set to work, we looked at the various parts and their function, so we could use the terms while doing examinations. http://www.microscope-microscope.org/basic/microscope-parts.htm
1) Eyepiece Lens vs. Objective Lens (ours has three magnifications, shortest lens=lowest power)
2) Stage with Clips (plate for slides)
3) Diaphragm/Iris (O discovered this! Rotating disc with holes of different sizes to vary the intensity of light)
4) Focus Knob
This particular scope is extremely child-friendly due to it's capabilities, but bare bones structure.


Our first specimen was Fairy Wings, otherwise known as maple keys; dried skeletons of the once-fresh version.
The fibrous veins looked amazing when magnified! Almost water-like!



O was quick to step up to the lens.
Since she can't wink with one eye, she decided to hold the opposite eye closed to focus.

Further Exploration

I left the room for a minute and returned to find O had retrieved the magnifying glass to examine a pine cone!
Highly impressed that she made the connection between a magnifying glass and microscope (even that she remembered that we own a magnifying glass!)
