Entry Events
Events that will be used to introduce the project to studentsMystery Food Labels
A selection of food products with intentionally obscured or misleading nutrition labels are presented. Students must use their existing knowledge and initial research to identify potential health impacts and marketing tactics, sparking inquiry into nutritional science.The Calorie Calculation Challenge
Students are presented with a complex, real-world scenario, such as planning meals for a high-performance athlete with specific dietary needs. They must calculate precise calorie and macro-nutrient breakdowns, highlighting the mathematical side of nutrition and the importance of precision.'Nutrition Myths' Debate
Introduce several common 'nutrition myths' (e.g., 'carbs are bad', 'fat makes you fat') and have students initially vote on their validity. This sets the stage for them to investigate the scientific evidence and engage in a structured debate, challenging preconceived notions.Design a 'Superfood' Campaign
Challenge students to invent a new 'superfood' product, complete with nutritional profile, marketing strategy, and target audience. This combines scientific understanding with creative problem-solving and encourages them to consider real-world applications.'Diet Disaster' Case Study
Present a fictional case study of an individual experiencing health problems due to a poorly planned diet. Students work backwards to identify the nutritional deficiencies and excesses, developing a revised dietary plan based on scientific principles.Portfolio Activities
