Middle School
Submitted by Leone Broadhead, The Elon School, Elon, NC
Here’s an inexpensive way to trap and observe diatoms from local bodies of water.
- Take a 7-oz Styrofoam® cup and carefully press a standard microscope slide through it so that a small section of slide protrudes from both sides of the cup, thus securing the slide. This is your diatom trap.
- Place the trap in a river, lake, stream, or pond, inverting the cup so that the slide is immersed in the water.
- Leave the trap in the water for several days. Diatoms will settle on the slide during the time it is immersed.
- Retrieve the trap from the water and carefully remove the slide from the cup. Place the slide under a microscope to view the diatoms.

The genomic landscapes of living organisms present vistas of almost limitless promise and offer challenges for people eager for knowledge, fortune, adventure, or contemplation. David Micklos, executive director of the Dolan DNA Learning Center, discusses the challenges (and opportunities) these new landscapes present to educators.
|  Digging into Earthworms
Earthworms are one of earth’s natural recyclers. They are also ideal specimens for teaching basic anatomy and investigating simple organ systems. Learn how to use these economical, convenient specimens to help students practice their dissection techniques before progressing to more complex specimens such as frogs or pigs.
