  ... Westwood College Project 1 Physical Science Research Paper Evan Duran PHYS212 October 8, 2013 Physical science is the study of physics and chemistry of nature. From the materialist and functionalist viewpoints it overlaps the life sciences where ecology studies the evidences of historical facts or evolution. Physics along with Mathematics and Chemistry is one of the fundamental sciences because the other natural sciences like biology, geology etc., deal with systems that seem to obey the laws of physics. According to Physics, the physical laws of matter, energy and the fundamental forces of nature govern the interactions between particles and physical entities (such as planets, molecules, atoms or the subatomic particles). Some of the basic pursuits of physics are describing the nature, measuring and quantifying of bodies and their motion, dynamics and so on. But what I want to touch up on is mass, force and weight. Considering that I am a Construction Management major, I believe these are the top key physics implemented in the pursuit of construction. Mass is a measure of the amount of material in an object, weight is the gravitational force acting on a body (although for trading purposes it is taken to mean the same as mass), force is a measure of the interaction between bodies and load usually means the force exerted on a surface or body....

  ...Weather Patterns and Climate Change Every place, country, city, region has its own climate. Climate plays one of the important roles in people’s life. Climate is defined as the average weather, which means variety of weather conditions as rain, snow, hail, sun, and wind over period of time about 30 years that can be measured in any particular place.( IPCC Third Assessment Report - Climate Change 2001; editor:A.P.Baede) Climate change is a variation of average weather. There are 2 causes of climate change. The first is human activity which includes deforestation, burning fossil fuels, agriculture, transportation and infrastructure. The second is natural causes which include volcanic eruptions and variations in solar outputs. These causes have negative effect on the natural environment which leads to increasing of temperature, increasing in sea level, changing of precipitations, extremely weather, killing species of animals, birds, fish and plants. This essay will show that the causes of climate change have different effects on the environment. Atmospheric carbon dioxide variations, volcanic eruptions and solar outputs, have negative impacts on animals, plants, and environment.  Climate is always changeable. One winter can be early, another late; one summer wet, another dry (Carter 2000,34). For the last century climate has dramatically changed. Consequences of climate change may manifest itself as rapid and through the long period of time. Climate change...

  ...of organizational change. In The Heart of Change, John Kotter and Dan Cohen describe eight steps that have lead organizations to successful large-scale change. The eight steps are as follows: 1. Increase Urgency, 2. Build the guiding team, 3. Get the vision right, 4. Communicate for buy-in, 5. Empower Action, 6. Create short-term wins, 7. Don’t let up and 8. Make change stick. This book offers real-life stories of companies going through large-scale-change efforts. It outlines the pitfalls they faced, the mistakes that were made and the lesson learned through the change process. Kotter and Cohen believe that change happens by making people feel differently through an approach that is referred to as see-feel-change. This method forces action as it shows people the reason for change by affecting their emotions. Furthermore, Kotter and Cohen believe that change fails because organizations rely too much on data gathering and reports to drive change instead of touching people’s feelings to encourage positive action. This book offers a play-by-play of the eight step approach Kotter and Cohen believe will change people’s behavior, which will enable any organization to overcome the resistance to change and bring about a successful change effort. In this paper, I will discuss four of the eight steps and show how Kotter and Cohen’s ideas relate to some of the theories and concepts in the textbook, Organizational Behavior and Management by John...

I want to thank Mr. Gorcowski for answering the questions that I had. Introduction UV light produced by the sun is blocked from the Earth’s atmosphere, but some still gets onto the earth. UV beads have a pigment the changes color when exposed to ultraviolet light radiation. The dye in the UV bead is photo chromic that changes color when exposed to UV, which is chemical reaction. Review Literature UV, or ultraviolet, light is an invisible form of electromagnetic radiation that has a shorter wavelength than the light humans can see. It carries more energy than visible light and can sometimes break bonds between atoms and molecules, altering the chemistry of materials exposed to it. Ultraviolet-sensitive beads are beads that change color in the presence of ultraviolet radiation. Ultraviolet rays are present in sunlight and light from various artificial sources, and can cause...
