Managing Live Insects

To raise an insect and watch its development is a great way to study not only insect biology but also insect behavior. The primary requirement for such study is to provide yourself a container to hold the insect; you can use any tightly sealed container with an opening for air. Glass jars work well because you can watch the insects through the glass. The air opening must be screened so that the insects can’t escape. Nylon material works well as a screen should be secured over the jar opening with a rubber band. Window screening is sturdier, but very small insects could escape. (more…)

Making a Collection of Insects

A collection of insects is always appealing for spectators especially on science fair projects. The collection may consist of the sample insect used in the project, any species of insects found in a single ecosystem, or even the life cycle or life stages that the insect takes which will be very useful for insect researches as specimen.

Insect Collection Project

Before pursuing any study of insects, it’s an excellent idea to get an insect field guide. A list of these guides can be bought from your local bookstores and many of these guides probably can be found in your local or school library or somehow found on science books you already have purchased. Field guides do more than just match pictures and names of insects; some guides even explain the traits that distinguish insects from each other, explain insect’s life cycles and behaviors and usually describe how to collect, preserve, and rear insects.

Crystals Under The Microscope

With a microscope, you can watch a crystal garden grow right on a glass slide. You can do this by dissolving two tablespoon of salt in one-quarter cup of water. You will notice that some of the salt will remain in the bottom of the cup.

Next, place a drop of the clear liquid on a slide and let it spread a little. Put the slide aside, without the cover slip, for a few minutes. Or you could also move it back and forth under a warm light bulb until the solution begins to dry. (more…)
