This course introduces students to climate studies, including beginnings of the solar system, time scales, and climate in human history. It is offered to both undergraduate and graduate students with different requirements.

The objective of this course is to develop an understanding of principles of marine isotope geochemistry, its systematics, and its application to the study of the behavior and history of the oceans within the earth system. The emphasis is on developing the underlying concepts and theory as well as proficiency in working with practical isotope systems. The course is divided into four sections: nuclear systematics, Earth formation and evolution, stable isotopes, and applications to the ocean system.

Throughout this series we’ve mostly talked about pairs of electrons, but electrons don’t always have a buddy. An atom or group of atoms with a single unpaired electron is called a radical. In this episode of Crash Course Organic Chemistry, we’ll learn all about radicals including the three key steps in a radical reaction and Hammond’s Postulate, an important tool to help us understand these reactions. We’ll also see ways radicals can react with alkanes, alkenes, and alkynes.

Conceptual Chemistry is a year-long course based on CK-12 OER instructional material and supplemented with limited commercially-available materials. The course is project-based, argument-driven inquiry. Each quarter begins with presentation of an intriguing phenomenon, followed by an essential question about the phenomenon, and a project centered on answering that essential question. Throughout the quarter, students conduct research and investigations to answer portions of the question. Each unit has a student "Task" at the end that serves as an assessment of the unit's concepts. At the end of each quarter, students assemble all of the unit tasks and synthesize a personal final project that answers the essential question in a personal context chosen by the student.

We’ve already learned a lot about electrophilic aromatic substitution (EAS) and benzene, but guess what? There’s even more to learn! In this episode of Crash Course Organic Chemistry we’ll revisit our old friends the Friedel-Crafts reactions and learn some of their limitations and look at where substitution happens when there are multiple directing groups on a benzene ring. Plus we’ll introduce some benzylic reactions!

As we construct more complex organic molecules, it can start to feel like decrypting a complex code. Organic synthesis takes simple starting materials, and turns them into complex structures, and reverse engineering can help us figure out the steps in between. In this episode of Crash Course Organic Chemistry, we’ll practice multistep synthesis problems, learn about how we can use retro synthesis to make more complex molecules, and use liquid-liquid extraction to separate solvents. As always, we’ll work through examples and connect everything back to our Mold Medicine Map!

This guided inquiry learning activity is designed to be used in a large introductory chemistry course. By working in small groups to discuss the presented information and question prompts, students will engage in cycles of exploring and analyzing data, inventing new conceptual understandings, and applying those concepts. Students should be tasked with working together to complete the prompts in each section by a set time limit. After each section is completed, the entire class can share their answers via a personal response system, and the instructor can review and explain the correct responses, using the accompanying slide deck, which translates the problems into multiple-choice prompts.Instructional resources include 1) the learning activity (.docx and .pdf) 2) the learning objects (.docx and .pdf) and 3) the slide deck (.pptx).- Atomic Orbitals- Chemical Fuels- Gas Laws- Intermolecular Forces- pKa Trends- VSEPR

This 14-minute video lesson looks at common and systematic naming: Iso, Sec, and Tert Prefixes. [Organic Chemistry playlist: Lesson 5 of 73].

Although we've spent a lot of time in this series looking at human-made organic chemicals, the term "organic chemistry" was originally used to describe molecules isolated from living things. In this episode of Crash Course Organic Chemistry, we're going back to our roots to learn more about the best synthetic chemists: living things. We'll look at the biochemical building blocks of life from the nitrogenous bases, sugars, and phosphate groups that make up DNA and RNA, to amino acids and lipids, and we'll learn how to convert between Fischer and Haworth projections of carbohydrates.

Going out in the sun can work wonders for your mood, but unfortunately too much UV exposure can do serious damage to your DNA. This damage occurs through a type of organic reaction called a pericyclic reaction. In this episode of Crash Course Organic Chemistry, we’ll explore pericyclic reactions to see how the sun can both give us life, and hurt us, and also look at other important pericyclic reactions, such as the Diels-Alder reaction.

Today Hank talks about the deliciousness of alkenes & alkynes, their structures, and how to remember which is which by simply knowing the alphabet. Also, he breaks down hydrogenation, halogenation, polymerization, and triglycerides all while helping us figure out the meaning of different names for fats.

The goal of this project is to insert sustainability concepts and issues into the general chemistry curriculum. Specifically, I focus on carbon as the example to be considered throughout the quarter.

This lesson explores the chemistry of some of the greenhouse gases that affect Earth's climate. Third in a series of 9 lessons from an online module entitled 'Visualizing and Understanding the Science of Climate Change'.

There are many misconceptions about the chemistry concept, “Conservation of Mass”. Thus, the aim of this video lesson is to teach students about the chemical concept of Conservation of Mass through several chemistry experiments. The students will carry out experiments while assisting a fortune teller named Pak Belalang to gain victory for his kingdom. In an effort to help Pak Belalang, students should be able to answer all the questions related to the Conservation of Mass that are posed by an evil witch. In this video, materials such as a box of matches, a closed and open container, a box of panadol soluble tablets (Alka-Seltzer), and weighing scales are needed. At the end of the lesson, students will be able to see that mass is “conserved”. The lesson will take up to 60 minutes to complete.

This 11-minute video lesson looks at the relative Stability of amides, esters, anhydrides, and acyl chlorides. [Organic Chemistry playlist: Lesson 71 of 73].

In this activity students will create their own toothpaste exploring and experiementing with natural ingredients.

Esters have a wide range of uses, from giving perfumes and colognes their fragrances, to preventing diseases like scurvy. Vitamin C, that scurvy preventing antioxidant, is derived from carboxylic acids, a class of organic compounds we’ve already learned a lot about! In this episode of Crash Course Organic Chemistry, we’ll look at four different carboxylic acid derivatives and their reactivities, react them with nucleophiles, and learn some hydrolysis reaction mechanisms that we can use in our synthesis of penicillin!

Insects can communicate with each other about all kinds of things, but instead of using words, they use… you guessed it! Organic Chemistry! Insects can send signals to each other by secreting compounds, and one such compound used by termites contains the functional group we’re going to learn all about in this episode: enones! In this episode of Crash Course Organic Chemistry, we’ll learn about crossed aldol reactions, the formation of kinetic and thermodynamic enolates, hard and soft nucleophiles, conjugate addition, and of course, enones!

Functional groups? Functional groups within functional groups? Hank takes today's Crash Course video to discuss some confusing ideas about Hydrocarbon Derivatives but then makes it all make more sense.
