Make sure you've completed the How to Use a Microscope activity before you start here!
Anytime you have a specimen that needs water to live, you'll need to prepare a wet mount slide. This is especially useful for looking at pond water (or scum), plants, protists (single-cell animals), mold, etc. When you keep your specimen alive in their environment, you not only get to observe it, but also how it eats, lives, breathes, and interacts in its environment.
The best way is to take a photo, because you cannot permanently keep wet mounts. During our Microscopy classes, we go over this quite a bit, so please refer to Unit 26.
how do you keep a wet mount slide safe for a long time?
