July 28st‚ 2014 Lab #10 Properties of Light Purpose: The ideal purpose of this lab activity is to investigate the relationship between the frequency of the light (color) and the energy produced by different colors of light. Other purposes of this experiment include calculating the proper current for each LED‚ measuring the evaporation rate of rubbing alcohol‚ and being able to discuss the outcome of the relationship in light energy and the color of the light producing the energy.

our perceptions of of how other members of our social groups think and act. Social norms focus on peer influences which have a greater impact on individual behavior rather than biological‚ personality‚ familial‚ religious‚ cultural and other influences (Berkowitz & Perkins‚ 1986A; Perkins‚ 2002). Peer influences are based more on what we think our peers believe and do (the "perceived norm") than on their real beliefs and actions (the "actual norm"). This study will explore how the mere presence of

Purpose: The purpose of this experiment was to test and observe the physical and chemical properties of gases‚ and to use these properties to identify these gases when they are encountered. Procedure: Create a data table similar to that in the lab assistant to record your observations. Gather the following lab equipment: Goggles‚ test tubes‚ 24 well plate‚ Gas assembly with copper and plastic tubing and a #00 stopper‚ short stem pipet‚ rubber stopper #00 with one hole and a pipet tip with

Although Intellectual property can be catorigized under many aspects‚ not every idea the mind can think is included. The legal definition of intellectual property often abbreviated IP is ideas‚ inventions‚ artistic works‚ songs‚ business processes etc. In general terms is any commercialily viable product created out of a persons mental processes. The Coca Cola company for example has legal ownership of several factories‚ bottling equipment‚ trucks for transporting their product and the actual ingredient

WGSS 1- Body size and shape is a controversy subject in all cultures. Large-size is acceptable in some places around the world but the others would prefer the small size. We all have that idea “fat” means ugly‚ health issues and wrong habits of eating but that’s defiantly not true according to the chapter 4 some societies consider large women attractive and see their fat as an evidence of prosperity (The Beauty Ideal‚ 189). Also in the website Health At Every Size that there is myth about fat kills

An intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured. For example‚ the temperature of a system in thermal equilibrium is the same as the temperature of any part of it. If the system is divided the temperature of each subsystem is identical. The same applies to the density of a homogeneous system: if the system is divided in half‚ the mass and the volume change in the identical ratio and the density remains unchanged. According

location for applying light from the LED to the drop of alcohol while minimizing the effect of air currents on the evaporation rate. The eyedropper was used to place a single drop of isopropyl alcohol on an index card within the enclosure. The same size drop was used each time the step was repeated. The time it takes for the drop to evaporate without the LED present was recorded. The dark spot on the card caused by the alcohol was no longer visible. A flashlight was used to help with the observance

Identifying Group Roles The purpose of this paper was to apply Cragan and Wright’s major group roles model to a college classroom group. The first major group role identified by Cragan and Wright was Task Leader. Cragan and Wright defined Task Leader as “a mature person who has good problem-solving ability and has had training in leadership skills”. (p. 191) This role was present. For example‚ at the first meeting‚ Harry broke the silence by suggesting that they take turns and introduce themselves
