Lab 5 DECOMPOSITION (Nov 2‚ 2011) Introduction: Decomposition is the breakdown of organic material into its smaller molecules and elements. (This term is generally considered as a biotic process but one may find it also used to describe an abiotic process‚ e.g.‚ due to weathering.) The decomposing organisms may use the release of elements for nutrients and by breaking apart the carbon-carbon bonds in organic matter this can release energy for them. These smaller molecules and nutrient elements

Introduction. Friction was studied in this lab. The experiments were conducted using a clipboard glued to various surfaces with diffirentiating frictional properties. In order for us to test the varying Static friction or Kinetic friction we used a Newton force gauge‚ some wooden blocks‚ and a metal weight. The actual experiment consisted of two parts. The first part measured the net force‚ or more specific the net force required to overcome the kinetic friction coefficient‚ to move the block across

pneumatic trough‚ thermometer‚ screw clamp. DISCUSSION The quantitative relationship between the volume and the absolute temperature of a gas is summartzed in Charles’law. This law states: at constant pressure‚ the volume of a particular sample of gas is directly proportional to the absolute temperature. Charles’ law may be expressed mathematically: V ". T (constant pressure) V = kT o‚ : T = k (constant pressure) (1) (2) where V is volume‚ T is Kelvin temperature‚ and k is a proportionality constant

Objective: During this lab‚ you will investigate the relationship between the angle of an applied force and the magnitude of one component. You will compare your actual force with the theoretical force and provide a computer generated data table that calculates the theoretical values. You will graph your actual and theoretical values and provide a complete

once the melting point is reached‚ further heating leaves the temperature constant and starts breaking down the crystal structure. This continues until all the substancCis melted. If still more heat is added‚ the temperature once again starts to ~ i s e . To melt a given amount of different substances requires differing amounts of heat because of differences of crystal structure.

Lab 11: Animal Behavior Introduction Ethology is the study of animal behavior. There are two specific categories of behavior: learned ad innate. Orientation behaviors place the animal in their specific environment. Animals move away from sensory input in taxis where as behavior is the response to sensory input. Stimulus’ of light‚ heat‚ moisture‚ sound‚ or chemicals are mostly found in taxis. Kinesis is the movement that does not result in orientation with stimulus. When animals respond to each
