Here are some simple rules for naming polyatomic ions.
Polyatomic ions with more oxygen atoms will end in -ate, and those with fewer oxygen atoms will end in -ite. When there are more than two polyatomic ions composed of the same elements, the prefix hypo- indicates the least number of oxygen atoms, and the prefix per- will indicate the most oxygen per ion.
As I left off in my last post, I tried out Oppia.org by creating an exploration called “Dimensional Analysis for Chemistry.” In short, while the creation process is a little laborious depending on the complexity of the exploration, I was rather pleased with the content creation tools. In particular, I was impressed by the powerful options for setting the feedback rules for user responses. In my opinion, Oppia may have a place in a teacher’s tool belt–or it can just become a creative hobby. Here’s the good and the…almost good, to consider when you look at Oppia.org. Continue reading →
Our memorization suite, Study Putty, is secreting new content all the time. We’ve squeezed our brain-glands in order to produce learning tools on the topic of the oozy ol’ endocrine system.
Here you can memorize the names and locations of the endocrine glands. You can test yourself: given certain organs, what is endocrine and what is exocrine? You can also match important endocrine hormones to the glands that chiefly produce them.
A game of gland locations. Notice only four show at once–hit “new game” for a new set.

If you are a student looking for a new way to memorize the crud you have to cram for class, Study Putty would like to help.
Why do we beat quizzing yourself on that crinkled cheat sheet another twenty-seven times? Why do we top reading the same table in your textbook on endless repeat? (With prospects that thrilling, do I even need to say?) Well, let me tell you. Nay, let me show you. Does your normal way of studying look like this?

Think of Algodoo as a virtual playground. Algodoo brings the sophisticated Algoryx physics engine to anyone’s computer or tablet, to learn or to play–and the boundary between the two is pretty blurry no matter how you use it. Watch the magic unfold in this demo vid from Algodoo.
“Memorization” is a foul word in education. Students hate doing it. Teachers hate that their students spend so much time trying to cram data into their noggins when the point is really the concept, not the vocab. But this doesn’t change the fact that mastering ‘vocabulary’ — whether it be definitions, abbreviations, symbols, or formulas — is a crucial hurdle students must get over.
“Critical thought, evaluation, and synthesis all sit on the backbone of vocabulary.”
— Rachel Watson, Professional Academic Lecturer, Dept. of Molecular Biology at the University of Wyoming, non-fan of rote memorization, and creator of her own open courseware.
Matching names and formulae of common polyatomic ions.
Easing the student’s memorization burden is the idea behind Study Putty, our set of online learning activities currently under development and available for students to use.
Study Putty provides several straightforward ways to memorize information. It’s not a game or a sim, it’s just a variety of memorization activities for fundamental facts prerequisite to mastering important concepts. We are starting with the subject of chemistry and looking to grow into other fields. Our chemistry activities are designed to get the dirty job of memorization done so the student can move on with labs, with class, with life. All of our activities are free to use. Continue reading →
Learning-Laboratory is proud to present its fledgling and freely available online learning activity: Study Putty.
Like clay in your over-stressed fist, dear student, the learning tools at Study Putty will be moldable to your desires, both for content and for style. As we are starting out, we are limited to two game types (matching and fill-in-the-blank) and to a handful of topics in chemistry. But we intend to expand. Continue reading →
A Chemical Bond Breakdown by an Internet Chem Guru
Tyler DeWitt might be the Internet’s favorite chemistry teacher–well, after Walter White and Bill Nye the Science Guy. The reason why he’s up there on the list anyway has to do with his point-by-point, easy-to-follow, visually-oriented explanations of the very threshold concepts that students struggle with. The following is the first installment in his video series on ionic bonding. See his channel for the whole series, and for a myriad of other topics.
Social Media and Education: a Match Made in the Near Future?
With social media and mashable technology entering their heyday, one could imagine a great opportunity and, perhaps, an intriguing potential for competitive learning games. However, if you search the Facebook apps directory with the term `learning` or `education,` there won`t be a lot of results. And most of those results are going to be language learning software aimed at adults outside of the education system. Continue reading →
