Chemotaxis using C.elegans
C. elegans is a free-living nematode. It is small—growing to about 1 mm in length—and lives in the soil (especially in rotting vegetation) where it survives by feeding on microbes such as bacteria. A great lesson to do following this one is C. elegans and Alcohol.
Students design, conduct, and analyze a controlled experiment testing the taste and/or smell preferences of the roundworm.
Grade Level: 5-8
Lesson Length: 1-2 class periods
