Osmosis in Action: Water Movement Through Egg Membranes (Advanced/Biology/Hands-
This hands-on lab engages students in exploring the process of osmosis and water potential (Ψ) using de-shelled chicken eggs as model cells. By comparing changes in egg mass and volume in distilled water and corn syrup, students gain a clear understanding of tonicity, solute potential (Ψs), and cellular homeostasis. The activity reinforces key concepts in cell transport and helps students connect microscopic processes to real-world examples such as IV fluids, dehydration, and plant water balance

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
