Food Fermentation

In this middle school task, students develop an explanation for how one organism’s (lactobacillus) population growth in an ecosystem may cause the population growth of other organisms in the same ecosystem to decrease. The ecosystem students explore is food. This task intends to elicit student learning of the following NGSS dimensions:

Disciplinary Core Ideas
  • LS2.A: Interdependent Relationships in Ecosystems (MS)
Science and Engineering Practices
  • Analyzing and Interpreting Data (MS)
  • Engaging in Arguments from Evidence (MS)
Crosscutting Concepts
  • Cause and Effect (MS)

Media 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. [permalink]

More Cheese, Please

In this middle school task, students use models and data to explain why lactose intolerant people experience lots of gas, bloating, and diarrhea when they eat certain dairy products. Here, students explore models of lactose-tolerant and lactose-intolerant people to see how the inputs, outputs, and processes of each person’s digestive systems affect how they function to process dairy products. They then develop their own comparative model to explain why only lactose-intolerant people experience these painful symptoms. At the end of the task, students examine new data to recommend what types of dairy products lactose intolerant people might eat to cause less painful symptoms. This task intends to elicit student learning of the following NGSS dimensions:

Disciplinary Core Ideas
  • LS1.A: Structure & Function (MS)
Science and Engineering Practices
  • Developing and Using Models (MS)
  • Analyzing and Interpreting Data (MS)
Crosscutting Concepts
  • Systems and Systems Models (MS)

Postgame Analysis

In this high school 5E unit, students investigate how milk helps athletes recover from intense exercise. Students begin by observing a series of professional athletes undergoing intense exercise and drinking milk after their exercise sessions. Across a series of four modules, students figure out how exercise impacts the body and how milk helps with recovery. Students explore body temperature and water balance, heart and breathing rate increases, and muscle fatigue. To conclude the unit, students explore muscle recovery. [permalink]
