Engaging review and interactive demonstration activities help students explain and predict mechanisms of biological regulation. Part of Big Ideas 2 and 4. Sample AP-style essay questions included! • Diffusion—Add a twist to the classic dialysis tubing experiment. Acids and bases cause an indicator to change color as they diffuse through the dialysis tubing. What ions are involved? How does the cell membrane regulate the concentration of electrolytes? • Buffers—Buffers provide essential pH regulation in cells, blood, and the lungs and kidneys. Demonstrate the composition, reactions, and mechanism of buffer action. • Organism Regulation—Identify the different ways organisms regulate their bodies and respond to the environment with a colorful set of organism and habitat cards.
Practical, interesting and effective way to prepare students for the essay questions on the AP Biology Exam! Sample data and questions help students apply concepts from different topics within the broader context of regulation.
Includes enough materials to perform each activity at least three times.
