Hank gives us a tour of the most important table ever, including the life story of the obsessive man who championed it, Dmitri Mendeleev. The periodic table of elements is a concise, information-dense catalog of all of the different sorts of atoms in the universe, and it has a wealth of information to tell us if we can learn to read it.

Chapters:
Dmitri Mendeleev
Mendeleev's Organization of the Periodic Table
Relationships in the Periodic Table
Why Mendeleev Stood Out from his Colleagues
How the Periodic Table Could be Improved

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 researchers, identifying sources of environmental contamination can be like trying to find a needle in a haystack. And that’s if they’re lucky. Because in some cases, they may not even know what to look for. In this line of work, known as non-targeted analysis, high-powered detection technology is critical to generating chemical fingerprints for unknown compounds. Just as important, however, is an expansive database that matches those fingerprints to the correct compounds. But bigger isn’t necessarily better. Researchers from the United States Environmental Protection Agency have shown that a promising new resource called the CompTox Chemistry Dashboard can actually outperform larger, well-established chemical databases, pointing to streamlined approaches to ID-ing potentially harmful contaminants. The CompTox dashboard uses a ranking approach similar to that of the popular database ChemSpider..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

In this episode, we talk about Silicon Valley's namesake and how network solids are at the heart of it all. Hank also discusses Solid-State Semiconductors, N-Type and P-Type Semiconductors, Diodes, Transistors, Computer Chips, and Binary Code. All from the same thing that makes up sand!

This unit includes 10 lessons that culminate in a student created final product presentation on the factors that influence climate change through the lens of chemistry and oceanography using literacy strategies to conduct inquiry level research.

Using inquiry-based reading, student will examine an anchor text to formulate a question to guide their research and development of student driven projects. Throughout the unit, students will use a variety of texts, websites, and other resources to develop a product and presentation that exhibits their literacy and inquiry skills. Using inquiry-based reading, students will explore an anchor text and then develop their own essential and supporting questions to guide their research. Over the course of the unit, students will explore a variety of texts and grow in their knowledge of cellular organelles and in their ability to use informational text to support their inquiry and research.

Students write a research paper (750--1000 words) on a topic of global importance in chemistry, technology, health, environmental sustainability, or another related field. The paper explores the issue by identifying several communities affected by the issue in different ways. At the culmination of the project, students draw on a variety of media resources to describe the several perspectives, and conclude by advocating one approach to addressing the issue. Students assemble their own resources through library research, and are free to model their work on examples provided on the course Blackboard website.

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.

Atoms are a lot like us - we call their relationships "bonds," and there are many different types. Each kind of atomic relationship requires a different type of energy, but they all do best when they settle into the lowest stress situation possible. The nature of the bond between atoms is related to the distance between them and, like people, it also depends on how positive or negative they are. Unlike human relationships, we can analyze exactly what makes chemical relationships work, and that's what this episode is all about.

If you are paying attention, you will learn that chemical bonds form in order to minimize the energy difference between two atoms or ions; that those chemical bonds may be covalent if atoms share electrons, and that covalent bonds can share those electrons evenly or unevenly; that bonds can also be ionic if the electrons are transferred instead of shared: and how to calculate the energy transferred in an ionic bond using Coulomb's Law.
