Edvotek Chemotaxis: The Science Of Attraction

All organisms are affected by "scent" molecules in the environment, including a multicellular organism called Caenorhabditis elegans. These worms are composed of 959 somatic cells, of which 300 are neurons comprising organs for taste, smell, temperature and touch. In this experiment, your students will observe and record the phenomenon by which normal and mutant strains of C. elegans can direct their movement in response to certain chemicals in the environment.
