Curated OER
DNA the Easy Way (and "Gram Stain" Without the Mess)
Students visualize DNA from cells and explain the basis and importance of the Gram-stain reaction and to perform the KOH test equivalent.
Curated OER
DNA Sequencing Model Lab
Students pretend they are each genetic engineers with a test tube of unknown DNA (PCR'd) possibly taken from blood cells of someone with a genetic condition.
Curated OER
DNA Fingerprinting
Ninth graders investigate what restriction enzymes do, and explain how a DNA sample can link a suspect to a crime.
Curated OER
Wolf Pack in a Bottle
Students participate in an activity of a mock electrophoresis using paper chromatography to study DNA and genetic restriction mapping.
Curated OER
Extracting DNA
High schoolers develop understanding of DNA by modeling the process of DNA extraction. They study DNA, genes and chromosomes. After the basic information, students do an experiment in which they separate out DNA from peas.
Curated OER
DNA Isolation from Onion
Students apply measurement skills using the metric system. They explain the process of isolating DNA from other cell contents. They apply knowledge of cell structure to explain the process of isolating DNA.
Curated OER
"Chips" Off the Old Block?
Students study using analogies between common items or occurrences and science concepts. They use the analogy of cookie recipes to that of the DNA "recipes" for living things to help us explain more about mutations.
