Blood Glucose, Feedback, & Graphing: A Real-World Homeostasis Task for Grades 7–9 This NGSS-aligned review pack helps students understand how the body maintains balance through blood glucose regulation—and gives them structured, meaningful practice creating and analyzing graphs. Students apply life science content (glucose, insulin, nutrients, feedback loops) while building key skills in data interpretation, pattern recognition, and evidence-based reasoning—everything NGSS expects them to do.
