Earth Sciences Study Guide: Atmospheres

From Figure 4.2, describe the geographic locations where coastal upwelling is important (e.g., “west central and southwestern South America”). Upwelling causes some of the coldest surface temperatures on Earth. The low surface temperatures stabilize the overlying atmosphere, causing cool dry climates (deserts) to dominate the western edge of South America. Upwelling is important where coastlines…

Modern Physics

During the late 1890s the creation of the quantum mechanics and Einstein’s Relativity beckoned a new age in physics: modern physics.  The terminology of modern physics refers to any branch of physics, such as nuclear physics or electromagnetism, which was developed in the early twentieth century or older branches that were greatly influenced by twentieth…

Essay: Are Genetic Privacy Laws Necessary?

Genetic Privacy laws exists to prevent the abuse of genetic information. It is understood that these laws were created specifically to prohibit health insurance companies, employers and housing agencies from using genetic data to discriminate against citizens.  Genetic discrimination can be described as the unfair treatment of individuals by employers/insurance companies based on gene mutations…

Lab Answers: Uniformly Accelerated Motion (Incline)

Introduction This study focused on an object in motion with a uniform acceleration.  Using the Motion Encoder System and LoggerPro, the position, velocity, and time were taken and analyzed with the goal to determine linear and quadratic acceleration.  Interpreting the graphs allowed discovery of the affect of acceleration due to Earth’s gravity.  This was represented…

Lab Report: The impacts of salinity on modern agriculture

1.0 Background: A breakthrough scientific experiment conducted by ‘Carnegie Science’ found that soil salinity considerably affects the growth rate in plants.  The experiment found how plants create Abscisic Acid as a stress hormone when the endodermis is exposed to drought or saline environments. “The endodermis also acts as a guard, with Abscisic Acid, to prevent…

Lab Report: Determine The Percentage Of Water In Hydrated Calcium nitrate

Introduction: Our group had done 3 data sets for the same experiment process, and had recorded 3 groups of data. The aim of experiments was to determine the percentage of water in hydrated Ca(NO3)2. We obtained the percentages through experimental procedures of reacting Ca(NO3)2 with Na2CO3 , filtrating and drying CaCO3. The chemical equation of…
