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 →
What do you (or your students) need to learn? Need a memorization game? Let us know.
We now have memorization games to help you study the cranial nerves on Study Putty! Memorize the numbers and functions of each nerve, and also whether each is primarily sensory or primarily motor. Head on over and select either A&P or Nursing and you’re on your way to cranial nerve mastery.
Here are some additional study aids, courtesy of our passion for making cramming less sucky:
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?

New Physical Chemistry Topics Added to Our Free App
This week, we have new live content available on Study Putty: amino acids. Before you go callin’ your prof “a-mean-o” for making you memorize this stuff, know we’ve got your back.
When a p chem student told us she wasn’t finding exactly what she needed on Quizlet, we decided to come swinging in to save the day. Alright, all we did was upload a spreadsheet into our software. But anyway, we can certainly help you, as we helped her, to review the following topics:
Where the action happens: at the intersection of DINOSAURS AND SPORTS. POW!
Number Munchers: Vanished About the Same Time as Dinosaurs; Yes, I Know I’m Getting Old.
“Munchers” was a series of educational games produced by MECC through the 80’s and 90’s. I passed through the digestive tract of elementary education just in time to catch classics like Number Munchers, and MECC’s more famous non-Muncher title, Oregon Trail, whenever my class took a privileged jaunt down the hall to the hi-tech and new-fangled Apple IIe computer lab.
Like anything that shaped a generation, Number Munchers is subject to copycats, whether motivated by nostalgia or by the desire to occupy the original product’s commercial niche. MECC–or the Learning Company, which acquired it–vanished from the face of the Earth in 1999, and who knows whose intellectual property that little green…uh…whatever-he-is…is. So a search for “Number Munchers” on the Internet, the App Store, or Google Play will return several…tributes, I guess we can call them if we want to be kind? If being kind bores you and you’d rather be honest, what we find is a handful of slightly-off trademark knock-offs, all of them as weak compared to the real thing as a Go-Bot was to a Transformer…I’m dating myself again aren’t I?

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.
