Carbon-carbon double bonds are pretty common in nature, but triple bonds between carbons, called alkynes, are not. When alkynes do pop up in nature, it’s usually in a compound that’s toxic to humans, however, we can synthesize alkynes that are life saving medicines and materials. In this episode of Crash Course Organic Chemistry, we’ll learn about alkynes and some of the reactions we can use them in (hint: it’s a lot of the same reactions we used for alkenes!)

Short Description:
This book explores the topic of anxiety disorders. Including information on neuroscience, assessment, and intervention.

Long Description:
Anxiety disorders are one of the most common mental health disorders experienced by people in the United States. However, given their complexity, they are also one of the most misunderstood. While these disorders can be quite debilitating, appropriate assessment, diagnosis, and treatment planning are critical to the recovery process.

The chapters introduce the reader to a variety of topics. The chapters include introduction to anxiety and the nervous system, building blocks of anxiety, assessing anxiety, and cognitive and behavioral interventions. The chapters were written to build upon one another. Thus, skipping a chapter and jumping ahead can be problematic as the reader may have missed foundational material in the prior chapters.

I would like to acknowledge that as part of this open educational resource product, there were several mental health providers that peer-reviewed these chapters. I would like to extend a deep gratitude for their time, edits, and constructive feedback.

But Dolly is six years younger."This kid-friendly Web page helps kids understand how and why Dolly was cloned, and understand the potential benefits of cloning as well as the controversy it raises.

In this lesson plan, the traditional autobiography writing project is given a twist as students write alphabiographies—recording an event, person, object, or feeling associated with each letter of the alphabet. Students are introduced to the idea of the alphabiography through a presentation giving the instructions of how to create guidelines for writing their own alphabiographies. Students create an entry for each letter of the alphabet, writing about an important event from their lives. After the entry for each letter, students sum up the stories by writing the life lessons they learned from the events. Since this type of autobiography breaks out of chronological order, students can choose what has been important in their lives. And since the writing pieces are short, even reluctant writers are eager to write!
