=Period 7=


 * Bell Ringer** - Draw a picture of a fictional macroinvertebrate. Remember to keep in mind the aquatic adaptations for the areas of the stream they would live in.

1. Check out the following sites: http://www.epa.gov/bioiweb1/html/benthosclean.html http://www.docstoc.com/docs/18224255/Macroinvertebrate-Identification-Key
 * Individual Work-**

2. Choose one of the macroinvertebrates from the above sites and draw it on the handout. Label key characteristics (legs, shell, tail, etc).

3. Ask Mrs. Murray for a Macro key. 4. Locate your macroinvertebrate on the key. Write the steps for keying out your macro next to your drawing.

5. Turn in your drawings to Mrs. Murray
