This illustration gives you the detailed information on classification of chromatographic methods. Chromatographic methods had 3 main types that is based on stationary, stationary phase format & mobile phase.

This exercise uses a number of Excel spreadsheets to calculate mineral formulae from compositional (microprobe) data. Numerous computational models are presented for most mineral groups (e.g. amphiboles, pyroxenes, micas), and students must critically evaluate which of these models is most applicable. Stoichiometry and charge balance are used to determine ferric/ferrous ratios--which is important for further applications such as geothermobarometry. Students are also asked directed questions about: compositional variation of the rock-forming mineral groups; representative complete, limited, and coupled solid solutions; site occupancy of major elements, as determined by the various computational models used; graphical representation of the calculated mineral formulae; and the composition and significance of certain varieties of these rock-forming minerals are addressed.

This is a spreadsheet that I use in petrology to walk students through calculating Rb-Sr isochrons and talking about isotope heterogeneity and sampling at various scales. The example exercise is the Tuolumne intrusive series. The file, available for download below, contains workbooks (see different tabs) with example isochrons and a spreadsheet of data for the homework problems.

This is Experiment #1 in the Analytical Chemistry Lab sequence at MSU Denver. It walks students through the calibration of three pieces of glassware and a micropipette. The Excel template is populated with prior student data so that calculations can be completed before lab and then updated with new data during lab. This allows for a mastery approach to the calibration, where students are able to repeat the calibration until the required tolerance is met.

The purpose of this exercise is to understand the capability and limitations of several instruments (AA, ICP-OES, ICP-MS) used for geochemical analysis. Students compare and contrast the cost, detection limits, etc. of these instruments.

In this assignment, students in small groups are asked to interpret and explain a figure depicting one aspect of marine carbon biogeochemistry. Then a representative of each group explains the figure to the class.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"For decades they’ve taken a backseat to their mineral counterparts. But today, organic materials are booming—not least of all for their applications in lithium-ion batteries. A new review article published in the journal ChemPlusChem discusses how one class of organics in particular is poised to yield high performance from a tiny but versatile package: carbonyl-based π-conjugated compounds. Like other organic materials, carbonyl-based π-conjugated materials present a unique and much-needed solution to the global energy crisis. Flexible, light, and naturally abundant, these compounds offer the prospect of nimble energy-storage systems with energy and power densities comparable to inorganic systems. What sets carbonyl-based π-conjugated materials apart from other organics is highly tunable electrochemical performance stemming from a versatile starting structure. The redox mechanism of carbonyls proceeds by a reversible one-electron reduction to form a radical mono-anion and the reverse reaction..."

The Careers in Green Chemistry and Sustainable Design video series highlight professionals in Washington whose careers impact products or chemicals used in Washington. Each of these videos highlight a career that connects to green chemistry and sustainable design. In each video, the professionals share their reflections in response to a series of interview questions. The videos are five to ten minutes long. They are designed to be used with secondary students.
It includes an activity guide to support teachers with using the video series with students.

This publication was produced as a teaching tool for college chemistry.The book is a text for a computer-based unit on the chemistry of acid-base titrations, and is designed for use with FORTRAN or BASIC.computer systems, and with a programmable electronic calculator, in a variety of educational settings. The text attempts to present computer programs that are relatively free of reliance on specialized large computer systems programs. The case-study approach presented is highly research and laboratory oriented. Similar subject matter is conventionally taught in most introductory college chemistry courses, but this text material attempts greater depth of instruction through utilization of the computational resources of a computer.

A case-study approach can be used to introduce students to the work that geologists do as environmental consultants. Data used by environmental consultants for a Brownfield site that is currently undergoing redevelopment in St. Paul, MN has been adapted for in-class study, either as a series of short exercises, or as part of a larger project.

There are two types of catalysis reactions: homogeneous and heterogeneous. In a homogeneous reaction, the catalyst is in the same phase as the reactants. In a heterogeneous reaction, the catalyst is in a different phase from the reactants. This activity addresses homogeneous catalysis.

This module teaches basic concepts in igneous petrology through relating hand specimen identification of lavas to major element geochemistry, using the Central American volcanic arc as an example.

Beginning in 2016, Chem 103/104 transitioned to a student-focused, active-learning philosophy. Students progress to mastery of the course learning objectives by engaging in frequent, structured activities. These activities may be performed individually (pre-class activities), in small groups (discussion, lab, and some whole-class activities), or with an entire lecture section with answers submitted via Top Hat student response system. A Module comprises a set of related content that generally approximates a traditional textbook chapter. Each module is broken into Quanta with distinctive pre-class (brief introduction to content followed by assessment quizzes) and whole-class (higher level content development, “ConcepTest” assessments of individual learning, and small group-oriented activities) activities. UW-Madison Chemistry 103/104 Resource Book supports these activities by providing learning objectives, in-depth descriptions of the content, many worked examples, practice problems, and a glossary for each quantum.

The purpose of this assignment is for students to synthesize field observations, petrography, and whole-rock chemical analyses in order to investigate chemical differentiation processes in a basaltic magma chamber. The students first complete a petrography lab on both hand samples and thin sections that represent a complete stratigraphic section through sill at Fort Lee, NJ. I then provide them with major- and trace-element data and a table of distribution coefficients for common phases that would be crystallizing from basaltic magma. I then ask them to discuss the chemical differentiation of the sill by writing up a 1-2 page interpretative summary based on their petrographic observations and the chemical data.

This is an undergraduate introductory laboratory subject in ocean chemistry and measurement. There are three main elements to the course: oceanic chemical sampling and analysis, instrumentation development for the ocean environment, and the larger field of ocean science.
This course is offered through The MIT/WHOI Joint Program. The MIT/WHOI Joint Program is one of the premier marine science graduate programs in the world. It draws on the complementary strengths and approaches of two great institutions: the Massachusetts Institute of Technology (MIT) and the Woods Hole Oceanographic Institution (WHOI).
