REU Program Summer Research. The REU summer research program focuses on interdisciplinary projects in sustainable chemistry. In our program, students become full members of a research group, carrying out fundamental research on topics that span the chemical sciences.

Discusses history of discoveries of antimatter particles, their existence in the universe, the huge instruments needed to create these particles (Stanford Linear Accelerator and CERN), and the energies involved when these particles and antiparticles collide. Talks about how antimatter is created for use in positron emission spectroscopy (PET) scans of the body.
February 2007 (pp 8-11) Author: Clair Wood Chemistry Connections: History/Biography, Nuclear, Sustainability Description: Traces historical theories about the composition and structure of the sun. Describes in detail nuclear fusion reactions that take place in the sun and explains how elements are produced from the hydrogen and helium which are the primary constituents of the sun.
The proton-proton pathways are given special emphasis. Describes the solar atmosphere—core, radiative zone, convective zone, photosphere, chromospheres and corona—and the processes that take place in each region. Concludes with a section on how the earth interacts with the sun and how the sun can be used as an alternative energy source. October 2009 (pp 6-8) Author: Carolyn Ruth Chemistry Connections: Atomic theory, Nuclear, Periodicity, Reactions Description: Describes the various processes for producing the various elements in stars of various types. Fusion, fission and “r” reactions detailed.

Follow the What? February 2008 (pp 16-19) Author: Lora Bleacher Chemistry Connections: Atomic Theory, Nuclear, Organic/Biochemistry Description: Describes the Sample Analysis at Mars (SAM) suite of instruments on board the Mars Science Laboratory (MSL), to land on Mars in late 2009 and stay there roving the surface collecting data. Instruments include laser spectrometer, gas chromatograph, and quadrupole mass spectrometer. Discussion of the value of studying carbon as an essential ingredient of life and its role in organic compounds ensues. Talks about isotopes of carbon providing information about the origin of the organic materials the SAM might detect.
ChemHistory: The New Alchemy October 2006 (pp 15-17) Author: Michael McClure Chemistry Connections: Atomic theory, History/Biography, Nuclear, Periodicity Description: Relates the history of discovering/explaining various nuclear reactions (fusion, radioactivity, fission, transmutation). Working with transuranium elements, Seaborg proposed actinide series. ChemMystery: Real or Fake? The James Ossuary Case February 2006 (pp 8-10) Author: Lois Fruen Chemistry Connections: Atomic Theory, Equilibrium, History/Biography, Nuclear, Organic/Biochemistry Description: Discusses methods used to authenticate antiquities, focusing on radiocarbon dating. The process and the background science are described. Other methods described: hardness and density testing, microscopic analysis of mineral composition, mass spectrometry to measure O-18 to O-16 isotope ratios.
Scientists reported the artifacts were fake, but then further research by other scientists refuted the fakery claims. The question remains unanswered. Chemistry centers on isotopic composition and presence of carbon dioxide in groundwater dissolving calcite (equilibrium equations provided).

December 2003 (pp 4-6) Author: Gail Kay Haines Chemistry Connections: Nuclear, Organic/Biochemistry, Reactions Description: Describes historical origins of the most widely used flavoring, vanilla, sources of natural and methods to synthesize vanillin, chemical methods of analysis (authenticate natural vs. Side bar describes most sensitive test using isotopic ratios of carbon to detect substitution of synthetic vanillin for natural.
Nuclear Chemistry Powerpoint
Unit Overview: This unit, called Passion, Power, and Peril, is an inter-disciplinary unit between two classes—English and Chemistry. In Chemistry class, students will learn about nuclear chemistry, but they will also research a specific aspect of the nuclear power industry. They will use this research in three ways. First, they will write a one-page paper for a Chemistry grade that explains how nuclear chemistry connects to the research topic. Second, students will write an informative/explanatory research paper that answers your research question by showing the complexity of the issue for an English grade. Finally, students will use their research and writing to create a piece of artwork for a multimedia art display designed to challenge the audience with weighing the costs and benefits of nuclear technology. In this process we would like students to consider the following questions: How does society evaluate costs and benefits of a technology?
What are the costs and benefits of nuclear power plants? Lesson Overview: This lesson aligns to the NGSS Disciplinary Core Idea of HS-PS1-8. Develop models to illustrate the changes in the composition of the nucleus of the atom and the energy released during the processes of fission, fusion, and radioactive decay because students are conducting research about nuclear power plants, which employ fission. Nuclear power also has a number of radioactive decay issues associated with the safe handling of nuclear fuel and waste, and future nuclear power plants may incorporate fusion as the method for extracting nuclear energy from the atom. It aligns to the NGSS Practice of the Scientist of Obtaining, evaluating, and communicating information because students will learn how to obtain information about their research topic and they will have to evaluate it for relevancy once they obtain it. In terms of prior knowledge or skills, my students have already had using databases subscribed to by, including Academic Onefile, the New York Times, and Science in Context. The materials needed for this lesson include computers with Internet access.
Mini-lesson: Our school librarian has me do a search for nuclear power. I get 65 million results. She makes the analogy of drinking from a fire hydrant—there is way too much water. She then asks me to limit my search in a couple of ways. First, she asks me to be more specific. I use quotation marks around the phrase “nuclear power plant employee health.” We get 1 result. Using the term “nuclear power plant worker health” yields 5 results, and two of them are quite useful to this topic.
At this point we make the point that Google searches can and should be targeted so that there is a limit to how many websites it produces in the results. We then spend time explaining what each of the tips on the library website is good for. We note that site:gov, site:edu. And site:org all give back searches only from these domain types.
For example, when my search term that I type into the search bar is site:gov nuclear waste I only get back results that are government related. Similarly, if my search term is inurl:nytimes nuclear waste I get 15,000 hits about articles from the New York Times about nuclear waste. Student Activity: Once we have gone over these options, we release students to conduct research. In some cases, students can get right to work independently by researching the that they were assigned in a previous lesson. However, some students have difficulty. Luckily for me, the school librarian is co-teaching with me and so the staff-student ratio is such that we are able to help every student who needs help. The biggest challenge that they face is coming up with just the right key word so that their search yields the type of result they are hoping for.
The librarian or I would try to help a student, and if one of us could not figure out the best search term, we consulted with one another. From this collaboration we produced list which we will refine for next year, but it is a good start for a list of key terms that students should use when they are conducting research. These samples of student work (, ) are typical indicators that students were able to use search terms effectively.
