Default Suggestions?

Hello,

Does somebody has some ideas for me?
I have just bought a microscope and I have considered some samples of sugar, NaCl and leafs, but I am wondering what to consider now.
So, does somebody has a suggestion for me?

Nadia.

Get an onion and peel off a thin layer of live tissue, not the dried part. Mount it on a slide, and you should be able to distinguish cells and material flowing between/around them.

There is enough stuff living in pond/lake/stream/river water to keep you busy for a very long time. If you live near the ocean, then you have even more to examine.

Insects provide some pretty amazing viewing opportunities. If you're lucky, you might even find some ectoparasites living on them.

From the garden: Very thin cross sections of herbaceous plant stems and roots.
Try to slice the epithelium layer on the ventral(bottom) surface of a leaf and see if you can identify the stomata.

From the human body: Cells can be easily removed from the inside of ones cheek by gently swabbing with a cotton "qtip" (earbud). Also, blood, and hair (try and pull out the follicle too (ouch!)) make interesting microscopic targets.

From the lake: Fish scales have concentric ridges one can count under low magnification to determine the age of the fish, much like the rings in a tree. Fillamentous and free living algae

The possibilities are really endless.
