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.
Science for Kids Water is an amazing substance! It can form into a beautiful snowflake in its solid state or evaporate into the air as a gas. Experiment with solids, liquids and gases to learn more about these states of matter. How do objects move? How far can a rubber band stretch? How does energy affect what we can see, hear or feel? Virtual Labs The Virtual Lab is an online simulation of a chemistry lab. It is designed to help students link chemical computations with authentic laboratory chemistry. The lab allows students to select from hundreds of standard reagents (aqueous) and manipulate them in a manner resembling a real lab. More information and offline downloads.

Home Common Compound Library A searchable database of over 800 common compound names, formulas, structures, and properties. Companion Notes Hyperlinked notes and guides for first semester general chemistry. Construction Kits Flash-based kits for building chemical formulas, names, equations, and problem solutions. Articles Featured articles, books, and tutorials. 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 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.
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. 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.

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. I reflected on the lesson and thought of ways to make it more accessible. Redox Rules Click to download REDOX RULES posters for VCE Chemistry What’s redox? We never learned that! 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.
The Map of Chemistry: New Animation Summarizes the Entire Field of Chemistry in 12 Minutes. 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.
