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.
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.
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!)

What the World's Made Of.
