Cat. #929 Aquatic Detectives: Solve the Mystery of the Contaminated Waterway
Cat. #920 Safari Family Reunion
For 8 Gels/8 Lab Groups. In this lab, students will per- form electrophoresis on the DNA samples of two lions in order to return them to wildlife sanctuaries close to their ancestral home. • Learn how DNA is used to discover an individual’s ancestry. • Perform DNA electrophoresis and RFLP analysis. • Analyze phylogenetic tree and haplotype maps. • Explore how conservation biologists use genetic data.
For 10 Groups. Water pollution has wide-reaching impacts on both wildlife and human populations. Contamination can enter the water supply from factories that discharge waste directly into a body of water. In this experiment, students will test simulated water samples to determine what contamination is present, and which factories contribute. • Introduce students to the importance of clean water for aquatic and terrestrial ecosystem diversity. • Perform water quality investigations to determine the site of water pollution. • Discuss real world problems and identify solutions.
