Carolina Investigations® for AP® Environmental Sciences: Agriculture and Feeding a Growing Human Population
After completing the Agriculture and Feeding a Growing Human Population inquiry, have each lab group use the scientific model checklist and construct either a 2-dimensional model or mathematical model of food production and consumption.
Base the model on this question:
How much of which food is needed to sustain a teenager who needs 2,000 calories a day?
Students may choose to create a pie chart, bar graph, or equation. A typical equation may look like this:
Total calories = (g of corn x Cal/g) + (g of almonds x Cal/g) + (g of beef x Cal/g)
Allow groups to switch models and critique them using the scientific model checklist. Models will vary based on the eating styles of the students. Go through as many refinements as time permits. Select the best model and display it on a “Super Models” poster or wall.
