It compares conflicting constructions about nuclear reactor safety, depleted uranium, Rachel Carson and DDT. Through analyzing diverse historic and contemporary media messages, students understand changing public knowledge, impressions and attitudes about chemicals in the environment. Sox Sperry Science and Technology Social Sciences 2013-03-04T10:17:35 Course Related Materials http://www.oercommons.org/courses/general-chemistry-ii-2 This second-semester course will cover several of the tools needed to study chemistry at a more advanced level. We will identify the factors that affect the speed of a reaction, learn how an atom bomb works on a chemical level, and discover how chemistry powers a light bulb. We will end with discussion of organic chemistry, a topic that is as important to biology as it is to chemistry.

In this course, we will study chemistry from the ground up, learning the basics of the atom and its behavior. We will apply this knowledge to understand the chemical properties of matter and the changes and reactions that take place in all types of matter. Upon successful completion of this course, students will be able to: Define the general term 'chemistry.' Distinguish between the physical and chemical properties of matter. Distinguish between mixtures and pure substances. Describe the arrangement of the periodic table. Perform mathematical operations involving significant figures. Convert measurements into scientific notation. Explain the law of conservation of mass, the law of definite composition, and the law of multiple proportions. Summarize the essential points of Dalton's atomic theory. Define the term 'atom.' Describe electron configurations. Draw Lewis structures for molecules. Name ionic and covalent compounds using the rules for nomenclature of inorganic compounds. Explain the relationship between enthalpy change and a reaction's tendency to occur.

They use chalk to see what happens when limestone is placed in liquids with different pH values. They also learn several things that engineers are doing to reduce the effects of acid rain.

They use their five senses sight, sound, smell, texture and taste to identify the other characteristics of each item.

They use a fluorescent compound as the dye to track through a series of dilution steps. They observe how the changing color intensity, or saturation, of each subsequent solution. They also keep a running calculation of the concentration dye in each serial dilution. Finally, using a UV lamp, they investigate whether the fluorescent dye can be detected after it disappears from view under normal lighting conditions. Matthew D. Cathell Mathematics and Statistics Science and Technology 2009-11-02T09:52:37 Course Related Materials http://www.oercommons.org/courses/engineering-and-the-periodic-table Students learn about the periodic table and how pervasive the elements are in our daily lives. After reviewing the table organization and facts about the first 20 elements, they play an element identification game. They also learn that engineers incorporate these elements into the design of new products and processes. Acting as computer and animation engineers, students creatively express their new knowledge by creating a superhero character based on of the elements they now know so well. Brian Kay Denise W. Carlson Lauren Cooper Malinda Schaefer Zarske Megan Podlogar Mathematics and Statistics Science and Technology 2009-11-02T09:52:37 Course Related Materials http://www.oercommons.org/courses/energy-forms-states-and-conversions The students participate in many demonstrations during the first day of this lesson to learn basic concepts related to the forms and states of energy. This knowledge is then applied the second day as they assess various everyday objects to determine what forms of energy are transformed to accomplish the object's intended task. The students use block diagrams to illustrate the form and state of energy flowing into and out of the process. Jan DeWaters Susan Powers Mathematics and Statistics Science and Technology 2009-11-02T09:52:37 Course Related Materials http://www.oercommons.org/courses/the-earth-is-a-changin This lesson introduces and describes the main types of erosion (i.e., chemical, water, wind, glacier and temperature). Students learn examples of each type of erosion and discuss how erosion changes the surface of the Earth. Students also learn why engineers need to be aware of the different types of erosion in order to protect structures and landmarks from the damaging effects erosion can cause. Figure 1 is an excellent illustration of water erosion.

Students rotate through stations and model each type of erosion on rocks, soils and minerals. The students record their observations and discuss the effects of erosion on the Earth's landscape. Students learn about how engineers are involved in the protection of landscapes and structures from erosion. Math problems are included to help students think about the effects of erosion in real-world scenarios.

Techniques and software for statistical sampling, simulation, data analysis and visualization. Use of statistical, quantum chemical, molecular dynamics, Monte Carlo, mesoscale and continuum methods to study fundamental physical phenomena encountered in the fields of computational physics, chemistry, mechanics, materials science, biology, and applied mathematics. Applications drawn from a range of disciplines to build a broad-based understanding of complex structures and interactions in problems where simulation is on equal-footing with theory and experiment. Term project allows development of individual interest. Student mentoring by a coordinated team of participating faculty from across the Institute.
