Butterfly Pea Flower Buffer Simulation Activity (Advanced Biology/AP/Worksheet)
This engaging activity introduces students to the critical role of buffers in maintaining homeostasis. Using butterfly pea flower tea as a natural pH indicator, citric acid as an acid source, and baking soda solution as a buffer, students investigate how biological systems resist drastic pH changes. Students will record data, construct graphs, and connect their results to real-world biological systems such as blood pH regulation, lactic acid buildup during exercise, and ocean acidification. Stan
