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:

"It’s a feared moment for every scientist: the discovery that years of painstaking research has led to results that can't be repeated. Many think that poorly characterized antibodies have contributed to this reproducibility crisis more than any other laboratory tool. A new study published in Molecular Cell supports this hypothesis, at least in the context of chromatin immunoprecipitation. Although accurate ChIP interpretation depends on near-perfect antibody specificity, the report shows that many of these reagents are far less capable than their advertising suggests, which calls into question several widely accepted paradigms on genomic regulation. The study focused on histone post-translational modifications; specifically all three methylation states of lysine 4 on histone H3. Through ChIP experiments, H3K4 methylation has been strongly linked to transcriptional control..."

This article and slide show from the New York Times, features several scientists from the University of Alaska, Fairbanks, who study the effects of thawing permafrost in Alaska.

In this laboratory exercise students will have an opportunity to examine the crystal structures, optical properties and health hazards of the common asbestos minerals. The laboratory will reinforce optical microscopic skills that students have learned in mineralogy and show them how mineralogy can be critical to understanding a current public policy issue.

Explore the interactions between various combinations of two atoms. Turn on the force arrows to see either the total force acting on the atoms or the individual attractive and repulsive forces. Try the "Adjustable Attraction" atom to see how changing the parameters affects the interaction.

This lesson introduces J. J. Thomson's discovery of the electron and E. Rutherford's planetary model of atomic structure. This is the first in a series covering modern atomic theory.

CHEMISTRY 2ND EDITION

Long Description:
Chemistry: Atoms First 2e is a peer-reviewed, openly licensed introductory textbook produced through a collaborative publishing partnership between OpenStax and the University of Connecticut and UConn Undergraduate Student Government Association.This text is an atoms-first adaptation of OpenStax Chemistry 2e. The intention of “atoms-first” involves a few basic principles: first, it introduces atomic and molecular structure much earlier than the traditional approach, and it threads these themes through subsequent chapters. This approach may be chosen as a way to delay the introduction of material such as stoichiometry that students traditionally find abstract and difficult, thereby allowing students time to acclimate their study skills to chemistry. Additionally, it gives students a basis for understanding the application of quantitative principles to the chemistry that underlies the entire course. It also aims to center the study of chemistry on the atomic foundation that many will expand upon in a later course covering organic chemistry, easing that transition when the time arrives.

The second edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Substantial improvements have been made in the figures, illustrations, and example exercises that support the text narrative. The first edition of Chemistry: Atoms First by OpenStax is available in web view here.

Chemistry is the study of matter, and all matter is made up of atoms. We will learn about elements, atomic number and mass, isotopes, moles (chemistry moles, not the animal), and compounds.

Oyster-Acidifying oceans dramatically stunt the growth of already threatened shellfish. This audio slideshow and video features scientists from Bodega Marine Lab and research on shellfish in Tomales Bay, CA.

Overview:

On this webpage you will find OER Chemistry textbooks along with supplemental materials and a few lecture videos.
The purpose of these discipline-specific pages is to display content that might be of interest to faculty who are considering adopting open educational resources for use in their classes. This list of content is by no means exhaustive. The nature of open educational resources is very collaborative and it is in that spirit that we encourage any comments about the content featured on this page or recommendations of content that are not already listed here.

This chemistry activity was created to enhance student learning around balancing chemical equations. It guides students through Phet simulations and then asks comprehension questions thereafter.

This module introduces balancing chemical reactions with stoichiometric coefficients.  Includes a link to an interactive website for practicing balancing reactions, a video showing specific practice problems, and a video with animations as visual aids demonstrating why we balance chemical reactions.

These recitation, lab, and chapter worksheet ancillary materials for basic chemistry courses were developed under a Round 13 Mini-Grant.

This assignment reviews basic of chemistry for students who should have had 2 introductory semesters of basic chemistry prior to enrolling in the Fundamental of Water Quality course for which the assignment is used. Assignment reviews basic equation balancing and questions about valence and concentration conversion that students will confront regularly in any geochemistry course.

This course covers the following questions. What are the predominant heat producing elements of the Earth? Where and how much are they? Are they present in the core of the Earth? Detection of antineutrinos generated in the Earth provides: 1) information on the sources of the terrestrial heat, 2) direct test of the Bulk Silicate Earth (BSE) model and 3) testing of non-conventional models of Earth's core. Use of antineutrinos to probe the deep interior of our planet is becoming practical due to recent fundamental advances in the antineutrino detectors.

In the master-equation formalism, a set of differential equations describe the time-evolution of the probability distribution of an ensemble of systems. This can be used, for example, to describe the varied mRNA copy numbers found in individual cells in a population.

The stochastic simulation algorithm (SSA, Kinetic Monte Carlo, Gillespie algorithm) produces an example trajectory for a particular member of a probabilistic ensemble by looping over the following steps. The current state of the system is used to determine the likelihood of each possible chemical reaction in relative comparison to the likelihoods for the other possible reactions, as well as to determine when the next reaction is expected. Pseudo-random numbers are drawn to "roll the dice" to determine exactly when the next reaction will proceed, and which kind of reaction it will happen to be.

This is an Excel spreadsheet and graph that illustrates standard "batch" and Rayleigh decarbonation models and how they can be used to detect fluid infiltration during metamorphism of carbonates. It makes a good lecture demonstration, but with a few modifications can be turned into a laboratory exercise. Key variables are "hotlinked" directly into the batch and Rayleigh models so students can adjust them to get a feel for the influence of different model parameters. The included carbon isotope data are from marbles in the Jervois region, central Australia (Cartwright et al., 1997). Oxygen isotope data are also included in the spreadsheet.

These Pre-Chemistry online modules are designed to function as chemistry preparation for first year chemistry students. It is particularly useful for students who, for various reasons, are otherwise not confident in their preparation for first year university level chemistry. However, the module can be used as a practical and valuable review for all students. The module focuses on the development of fundamental numeracy and problem solving skills that are widely applicable to students in a variety of first year chemistry courses including those directed to students in life science, engineering and natural and physical sciences. These modules function effectively in both online, hybrid or even as preparation for entirely traditionally delivered courses.

This text introductory chemistry text is aimed for a single semester or quarter beginning experience to the field. The textmaps survey some of the basic topics of chemistry. This survey should give student enough knowledge to appreciate the impact of chemistry in everyday life and, if necessary, prepare student for additional instruction in chemistry.
