Assess students' ability to compare healthy and unhealthy snacks by identifying examples, explaining in simple terms how key nutrients (e.g., protein, whole grains, fruits vs. added sugar and excess fat) affect short-term energy and long-term growth, and choosing the better option in brief, age-appropriate scenarios; tasks include classifying snacks, providing one or two child-friendly reasons for a choice, and recommending a snack for active play or rest.
