Nutrition Across Life Stages & Life Situations
Nutrition Across Life Stages & Life Situations
Nutrition changes throughout life because the body's physiological demands constantly evolve. Growth, aging, physical activity, pregnancy, lactation, and athletic performance all require unique energy and nutrient strategies. This comprehensive High School Biology resource helps students understand how nutrition supports health, metabolism, development, and human physiology across every stage of life.
Designed for Grades 9–12, this instructional unit combines Biology, Human Physiology, Nutrition, and Health Science while promoting inquiry-based learning, scientific reasoning, and evidence-based decision-making.
Product Description
Students begin by investigating nutritional requirements during childhood and adolescence, examining growth, hormone regulation, skeletal development, cognitive development, and changing energy requirements.
The next section explores adulthood by introducing basal metabolic rate (BMR), Physical Activity Level (PAL), total energy expenditure, healthy dietary patterns, and long-term disease prevention.
Students then analyze nutrition in older adulthood, investigating sarcopenia, osteoporosis, changing metabolism, nutrient density, hydration, and age-related physiological adaptations.
Special life situations—including endurance sports, strength training, pregnancy, and lactation—allow students to compare changing energy requirements, macronutrient distribution, micronutrient needs, and evidence-based dietary recommendations.
Throughout the curriculum, authentic case studies, nutrition planning activities, comparison charts, scientific diagrams, inquiry-based investigations, and differentiated classroom tasks encourage students to apply biology to real-world health decisions.
