Examining Genetic Diversity in Disjunct Populations using Random DNA Markers
Molecular biological techniques are used to study naturally occurring genetic variation, and have greatly facilitated the understanding of problems in many areas of biology. In this lab, we examine two populations of terrestrial isopods in the Family Armadillidiidae using Random Amplification of Polymorphic DNA (RAPD Analysis). RAPDs are robust and generally species-independent. Using this technique, we are able to detect and analyze genetic variation within and between two different populations

Who Needs What?
The teacher leads a discussion in which students identify the physical needs of animals, and then speculate on the needs of plants. With guidance from the teacher, the students then help design an experiment that can take place in the classroom to test whether or not plants need light and water in order to grow. Sunflower seeds are planted in plastic cups, and once germinated, are exposed to different conditions. In particular, within the classroom setting it is easy to test for the effects of l
Using Macroinvertebrates to Evaluate the Condition of Ponds
