Ap Biology Surface Tension Lab at Joy Dawn blog

Ap Biology Surface Tension Lab. Students will need to use scientific reasoning to explain how soap affects hydrogen bonds using terms such as cohesion, surface tension and polarity. How does soap affect the water's surface tension? Lab station activity that explores the properties of water, such as cohesion, adhesion, polarity, and surface tension. The result of this is surface tension—a net attractive force that tends to pull adjacent surface molecules inward, thus decreasing the surface area to the smallest possible size. Students complete tasks at each stations and summarize. Use pennies, soap, and a pipet to conduct a lab on the surface tension. Water has a high surface tension because of the hydrogen bonds that hold water molecules to each other, this creates a ‘net’ of water molecules. Develop a hypothesis that answers the experimental question. In this lab you will learn about properties of liquids, specifically cohesion, adhesion, and surface tension. Test the number of drops that can be placed on penny and compare that test to drops that contain soap, data is analyzed using statistics. Reinforce principles of the scientific method: These principles will be demonstrated by adding drops of different liquids to pennies to. At the surface of water, molecules are more densely packed because they are not being pulled from above, resulting in stronger intermolecular forces.
