The objective of this experiment is to use chromogenic reagents to test simulations of water samples contaminated with known bacteria. As an extension, students will apply this test as a field activity to screen local bodies of water for the presence of coliform bacteria.
In this experiment, students will monitor water quality by using the Polymerase Chain reaction to detect the presence of bacterial contamination.
Main theme: Natural selection, artificial selection, genetic modification & cloning all result in same thing – desired or most fit phenotypes, but the processes are different and have different ethical considerations.
MAIN THEME: DNA is underlying information storage and is the hereditary unit of life on Earth. Conceptualize genetic diversity & its relationship to DNA, RNA & proteins Examine genetic and species diversity Recognize gene variability through alleles Define heterozygous, homozygous & epigenetics and their influence on genotype & phenotype Predict inherited genotypes and phenotypes with virus models Epigenetics Listening homework: http://www.radiolab.org/story/251885-you-are-what-your-grandpa-eats/ Virus models and hereditary dominance/recessive worksheet
