Teacher Tip: Diatom Trap |

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, steam, 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.
