In this project, much of the learning responsibility is placed on the individual students within the project team, and also on the team acting as a cooperative unit. Students will be provided with some basic background and will have some avenues to investigate and present as a team (polar vs. nonpolar compounds and surface area, hydrophilicity vs. hydrophobicity, the history of mass spectroscopy, the advantages and disadvantages of longitudinal studies, the specialization of scientific fields, and the importance of collaboration between experts in different scientific fields.

Analytical chemistry spans nearly all areas of chemistry but involves the development of tools and methods to measure physical properties of substances and apply those techniques to the identification of their presence (qualitative analysis) and quantify the amount present (quantitative analysis) of species in a wide variety of settings.

As currently taught in the United States, introductory courses in analytical chemistryemphasize quantitative (and sometimes qualitative) methods of analysis along with a heavydose of equilibrium chemistry. Analytical chemistry, however, is much more than a collection ofanalytical methods and an understanding of equilibrium chemistry; it is an approach to solvingchemical problems. Although equilibrium chemistry and analytical methods are important, theircoverage should not come at the expense of other equally important topics.
The introductory course in analytical chemistry is the ideal place in the undergraduate chemistry curriculum forexploring topics such as experimental design, sampling, calibration strategies, standardization,optimization, statistics, and the validation of experimental results. Analytical methods comeand go, but best practices for designing and validating analytical methods are universal. Becausechemistry is an experimental science it is essential that all chemistry students understand theimportance of making good measurements.
My goal in preparing this textbook is to find a more appropriate balance between theoryand practice, between “classical” and “modern” analytical methods, between analyzing samplesand collecting samples and preparing them for analysis, and between analytical methods anddata analysis. There is more material here than anyone can cover in one semester; it is myhope that the diversity of topics will meet the needs of different instructors, while, perhaps,suggesting some new topics to cover.

This is Experiment #5 in the Analytical Chemistry Lab sequence at MSU Denver. In this experiment, students will use two methods to determine the concentration of two food dyes in a sports beverage.Spectrophotometric analysis with linear least squares regressionHigh Performance Liquid Chromatography (HPLC) analysisStudents will learn quantitative methods with spectroscopy and learn to interpret a chromatogram to create a calibration model. Then students will compare and contrast the methods and report their results in a technical write-up.

In this activity, students examine a photograph of the night sky and answer questions about their observations. The picture, taken by a high school student in upstate New York, offers insight into the Earth's rotation, apparent star motion, the location of Polaris (the North Star), circumpolar constellations, and pointer stars.

Instructional sequences are more coherent when students investigate compelling natural phenomena (in science) or work on meaningful design problems (in engineering) by engaging in the science and engineering practices. We refer to these phenomena and design problems here as ‘anchors.’Here is a tool to assist in determining if the elements of the anchoring phenomenon are strong or could use some additional thinking.

This open course with a new set of ancillary materials for OpenStax Chemistry was created under a Round Eleven Mini-Grant for Ancillary Materials Creation and Revision. The materials created in order to support faculty implementing OpenStax Psychology in the classroom include:
Lecture Slides Chapter Checklists Practice Problems Newly-Created Videos
Along with these resources, the open course also contains a laboratory section with new instructional videos, a laboratory notebook and a sample notebook with responses, and experiments for each course.

The purpose of this video lesson is to expand the student's knowledge about enzymes by introducing the antioxidant enzymes that are intimately involved in the prevention of cellular damage and eventual slowing of the aging process and prevention of several diseases. Students will learn that natural antioxidant enzymes are manufactured in the body and provide an important defense against free radicals. The topic of free radical action is introduced, covering how they are constantly generated in living cells both by ''accidents of chemistry'' and also by specific metabolic processes.

In this problem set students are given Rb/Sr and 87Sr/86Sr data for whole rock and mineral samples from three granitic intrusions in the Sierra Nevada. They use these data (in EXCEL) to calculate isochron ages and initial ages for the intrusions and then interpret their results. This problem is intended to teach some spreadsheet skills (linear regressions, graphing) as well as having them think about the use of radiogenic isotopes.
