Main Theme: DNA is underlying information storage and hereditary unit of life on Earth. Learning Objectives 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 […]
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. Learning Objectives Predict offspring phenotypes & genotypes Differentiate between natural selection, artificial selection & genetic modification & cloning Appreciate benefits of genetically modified organisms (GMOs) Clarify concerns […]

In this experiment, students will monitor water quality by using the Polymerase Chain reaction to detect the presence of bacterial contamination.
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.
Introduction A human crisis of unprecedented proportions is in the making. Diminishing arable land, water shortage, and expected population growth to 10 billion portend a catastrophic food security crisis by 2030. This threat requires a dramatic reduction of the environmental footprint of agricultural practices. A paradigm shift to the food supply chain is necessary to […]
