Surface Tension Steven Brignol Dr. Payne September 15 Introduction: Water’s ability to stick to itself is surface tension. In this lab we were able to measure and detect surface tension by dropping water‚ drop by drop‚ onto a penny. The quantity of droplets that fit on the penny was impressive. Hypothesis: The detergent will thicken the water making a tighter surface tension. Prediction: If soap increased the surface tension‚ then expansion will happen. Materials: (1) Pipette (2) Water

Darlene Garcia GEO 151 Prof. Denyse Lemaire WA1 Feb. 2010 1. What are the relationships among Earth’s mantle‚ crust‚ asthenosphere‚ and lithosphere? The core is divided into three major compositional layers. The crust on Earth’s surface‚ the rocky mantle beneath the crust and the metallic core which is the center of the Earth. While distinct and separate parts of Earth‚ they are all interconnected. The metallic inner core is solid‚ surrounded by a liquid (molten) outer core. Most of

However the changes will make it difficult to manage at some point depending of how often the changes are occurring and the support that will be provided. I can handle change and making transitions however‚ it will be difficult dealing with the change and setting a timeframe. Planning and Program Design Human service
