Increasingly, science teachers are seeking phenomena that will allow them to explore both scientific content and socially relevant issues. The authors describe a series of lessons that (1) model the exoneration of wrongly convicted individuals using the science of DNA analysis and (2) contextualize individual cases within a larger system where…

Approximately 1 billion metric tons of food are lost each year due to mycotoxins (FAO 2013), secondary metabolites produced by fungi (Marin et al. 2013) that contaminate crops (Placinta, D'Mello, and MacDonald 1999) and threaten the health of domestic animals and humans (Sobrova et al. 2010). The fungus "Fusarium graminearum" produces…

Production of liquid fuels such as ethanol from fibrous plant biomass could potentially be a significant sustainable component of the U.S. energy portfolio. Engineers and scientists are actively researching this area, and high school students can engage in this contemporary inquiry process by experimenting with different types of biomass, varying…

Every year, high school students hunch over microscopes and peer at a plethora of tiny creatures. Swimming single-celled protists and whirling multicellular rotifers often steal the show, preventing students from noticing the static algae. However, these frequently overlooked, ordinary algae are inspiring research all over the world as scientists…

In this guided inquiry, students investigate advantages and disadvantages of genetic engineering by integrating popular fiction into their study of bioethics. What are the effects of artificially created hybrid creatures on characters in "The Hunger Games" and in our society? What are the effects on and basic rights of the organisms…

At Oklahoma City Community College, they have developed gel electrophoresis activities that support active learning of many scientific concepts, including: pH, electrolysis, oxidation reduction, electrical currents, potentials, conductivity, molarity, gel electrophoresis, DNA and protein separation, and DNA fingerprinting. This article presents…

Presents a student simulation activity based on the dideoxy chain termination method of determining the nucleotide sequence of DNA fragments developed in 1977 by Fred Sanger. (JRH)

Presents an innovative, inquiry-oriented lesson plan for using biotechnology to teach evolution. Using acrylamide gel electrophoresis, students learn how to isolate and compare different proteins from the muscle tissue of readily available seafood specimens to determine phylogenetic relationships. Uses a 5E (engagement, exploration, explanation,…

Details a project in which successful DNA analysis techniques were developed by students and their teacher in a rural school. Focuses on a study of sage grouse. (DDR)

Describes an easy and inexpensive method of preparing experimental growth media that high school students can use for plant cloning investigations. (PR)

Biotechnology has arrived in the supermarket in the form of genetically engineered enzymes. Presents an activity in which students explore the presence of protease enzymes in laundry detergents. (MDH)
