Unravel Genetics to Raise the Steaks

NGSS Design Badge Unravel genetics

In this high school 5E unit, students investigate how beef cattle have gotten bigger over time. Students begin by observing a series of images of wild animals and comparing them to animals raised by humans for food production and pay particular attention to beef cattle and the changes in size from the historical perspective to the present day. Across a series of four modules, students figure out how genetics related to cattle breeds and environmental factors such as climate, nutrition, and stress impact cattle growth and performance over time. Students conclude the unit by applying their understanding of how these factors have influenced growth trends in other animals that are raised for food.

Media Mayhem

NGSS Design Badge Full unit mayhem

Is the production of milk good or bad for the environment? Conflicting media claims tell opposing views, which can be difficult for students to understand. In this high school 5E unit on the dairy food system and sustainability, students explore media claims about the impacts of the dairy sector on the environment to figure out which ones most accurately represent the body of science on the dairy sector’s impacts. Across a series of four modules, students figure out how the components of the dairy food system impact the environment, including pollution, greenhouse gas emissions, climate, and biodiversity. To conclude the unit, students use engineering design processes to evaluate multiple solutions to reduce the dairy sector’s environmental impact.
