How to Bring a General Chemistry Lab Course Online. JoVE in Action is a series of blog posts highlighting how STEM educators around the world have used JoVE to support their remote teaching efforts.
We hope these stories will be useful for instructors looking for effective ways to deliver their science and lab courses online or in hybrid formats. Dr. Kathryn Allen is an Assistant Professor of Chemistry at Millersville University. When her institution moved to remote instruction this past spring, she, like many educators worldwide, had to shift her courses online. The Guardian view on the periodic table: better living through chemistry. This year marks the 150th anniversary of the discovery, or invention, of the periodic table of the elements, one of the most important, if least dramatic, of all scientific breakthroughs.
Chemistry has a bad reputation among non-chemists, perhaps because it is the first place in science where a schoolchild comes up against the stubborn complexity of nature. The organising principles of physics appear simple; evolution makes biology appear a well-ordered process, at least until it’s examined in detail. But chemistry is awkward and lumpy. There are endless facts to memorise, and there are few obvious and intuitively pleasing answers to questions such as why the periodic table has eight columns and not seven or nine.

Philosophers, technologists, and futurists spend a good deal of time obsessing about the nature of reality.
Recently, no small number of such people have come together to endorse the so-called “simulation argument,” the mind-boggling, sci-fi idea that everything we experience exists as a virtual performance inside a computer system more sophisticated than we could ever imagine. It’s a scenario right out of Philip K. Dick, and one Dick believed possible. It’s also, perhaps, terminally theoretical and impossible to verify. So... where might the perplexed turn should they want to understand the world around them? Walliman’s ingenious teaching tools excel in conveying a tremendous amount of complex information in a comprehensive and intelligible way. Energy Foundations for High School Chemistry. What's an Ion?

Molecular Polarity. Polarity - Dipole: Polarity results from the uneven partial charge distribution between various atoms in a compound.
Atoms, such as nitrogen, oxygen, and halogens, that are more electronegative have a tendency to have partial negative charges. Atoms, such as carbon and hydrogen, have a tendency to be more neutral or have partial positive charges. Electrons in a polar covalent bond are unequally shared between the two bonded atoms, which results in partial positive and negative charges.
Construct a Lewis Structure. Redox Rules. Click to download REDOX RULES posters for VCE Chemistry What’s redox?
We never learned that! Yes, you did. I use the term “redox” to refer to all of the following chapters in Heinemann Chemistry 2, which you will have learned at the end of Term 3 (September). Chapter 26: Redox (revision of Year 11)Chapter 27: Galvanic CellsChapter 28: Electrolytic Cells Don’t underestimate redox The VCAA has consistently used redox to discriminate which schools and students have the self-discipline required to keep studying at the end of the year. Here are some popular redox lies (misconceptions) Teach "naming compounds" with a decision tree - Jen Siler's Classroom. Naming compounds was a frustrating topic This is a topic that my Chemistry students always struggled with.
There are just so many rules! They were becoming frustrated and giving up. So I did what I always do when my kids are having trouble. 50 Awesome Chemistry Videos For The Busy Science Teacher. Though we don’t often recognize it, chemistry defines nearly every element of our everyday lives.
From the reactions that fuel the sun to the biology of our bodies to the technology in our gadgets, chemistry is at the heart of everything we do and is the central science that unites biology, physics, geology, astronomy, medicine, and countless other fields. Yet chemistry doesn’t always get the credit and recognition it deserves for playing such an awesome role in, well, everything. If you’ve been slighting chemistry, there’s no better time to give the field the credit it deserves than National Chemistry Week.
Founded in 1987, the week-long event has helped bring awareness to the role chemistry plays both in our lives today and in our future. You can get in the spirit of the event by checking out a few (or all) of these amazing chemistry videos online. Amazing Reactions and Experiments Brainiac: Thermite and Liquid Nitrogen: Think thermite reactions are super awesome? Chemicals in the Home : Basic Chemistry. This page is intended to help students of basic (school-level) chemistry with questions such as: The following table of the chemical names and molecular formulae of common chemicals is arranged in alphabetical order of the common (often "household" or "domestic") name of the chemical.
If you are not sure what the molecular formulae mean you can look up the symbols by viewing the list of chemical elements (listed in alphabetical order of chemical symbol). You can also read more about molecular formulae of organic molecules. See also more molecular formulae of common chemicals. Chemistry, Organic Chemistry and Periodic Table. Chemistry Techniques – Titration.
Click to enlarge Anyone who’s studied chemistry will be overly familiar with titrations. It’s an analytical technique that can be used to find the concentration of a solution (the amount of a solute dissolved in it). I put this graphic together primarily to remind my A level students of some of the key aspects of titrations, but as well as being a handy guide for them, it’s a useful introduction to the technique for non-chemists too! Students are usually introduced to titrations in the context of reactions between acids and alkalis.

ChemGameTutor. The Particle Adventure. Chemistry — Cooler Than Absolute Zero! Here’s a look at the remarkable properties of ten of the periodic table’s elements. The first on our list was hailed as the philosophers’ stone when it was discovered. 1.
Phosphorus Phosphorus was the first element ever isolated scientifically. In 1669 Hennig Brand evaporated water from urine, then allowed the residue to fester for a few months. When he distilled the residue, one of the substances that appeared was phosphorus. Some alchemists thought Brand had discovered the philosophers’ stone! The Alchemist by Joseph Wright depicts Hennig Brand’s discovery of phosphorus. 2. Carbon forms more compounds than any other element. Carbon’s ability to bond with other elements makes it the ideal basis for life, such as this excited gull. 3.
