Students work in groups of two or three, groups are given four unidentified bottled waters in unmarked containers and the chemical characteristics taken from the label on the bottled waters. They devise and carry out a plan to match the water in the unmarked containers with the appropriate labels. Full Review »

Students conduct an experiment in which they systematically separate cations from a mixture of substances. They use the following types of reactions to do so: precipitation, acids and bases, oxidation and reduction. They compare a standard solution to a waste-water solution to determine which cations are present. Full Review »

Students use this activity to simulate the sequencing of gene and to detect the presence of possible genetic defects. They use diagrams that represent bands of nucleotides in order to determine the sequence of a small piece of the CF gene. Students make comparisons between base sequences of pairs of chromosomes from individuals who are not affected by CF and those who are. Full Review »

Students research information on macroinvertebrate organisms and their environments and discover that tolerance to water quality conditions vary from organism to organism. Through their research they also determine how to identify aquatic organisms and discover how to assess water quality. Full Review »
