Internal Assessment IB Physics-7 Mr. Parent 14 January 2012 I. Design • Purpose: o To determine how the surface area of a coffee filter affects the average velocity of the coffee filter from the same height. • Variables: o Independent Variable ▪ Surface area- The area of the surface after the folds have been made o Dependent Variable ▪ The Average velocity- calculated by measuring the time and dividing by

GENTLY drop the tissue flat onto the surface of the water GENTLY place a dry paper clip flat onto the tissue (try not to touch the water or the tissue) Use the eraser end of the pencil to carefully poke the tissue (not the paper clip) until the tissue sinks. With some luck‚ the tissue will sink and leave the paper clip floating! How is this possible? With a little thing we scientists call SURFACE TENSION. Basically it means that there is a sort of skin on the surface of water where the water molecules

potato Peanut butter Soft drinks Chocolate coatings Caramels Emulsifiers are molecules that have two distinct ends. One end likes to be in water (hydrophilic) and the other end likes to be in oil (lipophilic). This means that they will coat the surface of oil droplets in an oil-in-water emulsion and effectively ’insulate’ the oil droplets from the water. It keeps them evenly dispersed throughout the emulsion and stops them from clumping together to form their own‚ separate layer. In a water-in-oil

1 Population growth and urban problem in Mumbai‚ India According to G.Tyler(1994)‚ the more poor people move from rural to urban area the more poverty is becoming urbanized. A lot of cities have damage because of the extreme poverty and social and environment in stead of being centers of commerce and industry. In this article I will discuss the problem of slum clearance in Mumbai‚ India. I am interested in poor people in urban area. First I will refer about population growth which is related

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

loss of soil from farmland may be reflected in reduced crop production potential‚ lower surface water quality and damaged drainage networks. Erosion by Water The rate and magnitude of soil erosion by water is controlled by the following factors: Rainfall Intensity and Runoff Both rainfall and runoff factors must be considered in assessing a water erosion problem. The impact of raindrops on the soil surface can break down soil aggregates and disperse the aggregate material. Lighter aggregate
