PHENOTYPIC AND GENOTYPIC CHANGES IN BACTERIA
Students use a rapid method to render the bacterium Escherichia coli "competent" in order to uptake plasmid DNA. They also have growth on the plain LB plates by the untransformed cells (which serve as controls). Students perform a cell...

Protein Synthesis Activities
Students compare the process of protein synthesis in an analogy. They simulate the process of protein synthesis kinesthetically using index cards and write a paragraph to explain the process.
Curated OER
ISOLATION OF DNA FROM ONION
Students perform a laboratory exercise designed to show how DNA can easily be extracted from onion cells. They conduct an optional test for the presence of DNA using standard lab equipment.

Who Done It?
Students work in groups to solve various murder mysteries using DNA evidence to implicate suspects. Teams compete to solve the crimes the fastest, while using various scientific methods to accomplish their task.
Curated OER
Food Forensics: A Case of Mistaken Identity
Students develop an experiment to test a hypothesis. They use their knowledge of antigen-antibody specificity to develop a hypothesis. Students articulate that the antibody-antigen specificity is one part of the immune system. They...
