# Beautiful Chemistry

### Zn + Pb(NO3)2 –> Pb + Zn(NO3)2, etc.

Want to see something metal? What could be more brutally metal than “lead trees”? Yes, trees of actual lead. A forest of them. And they are chillingly majestic. Granted, they’re tiny and in a solution, but I’m going to overlook that fact.

# How to Name Polyatomic Ions

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.

Less Oxygen More Oxygen
hypo- -ite -ate per-

## How to Make an Oppia Exploration (Ed Tech Reviews)

What is Oppia? Find out about Oppia.org in my previous post, Oppia: Opportunity for Progressive Learning or Open-Content Muddle?

# Creating the Dimensional Analysis Exploration

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

## Oppia: Opportunity for Progressive Learning or Open-Content Muddle?

Welcome graphic from Oppia.org

While aboutst the Web for other purposes, I had the pleasure of stumbling upon Oppia.org. Developed by some Googlers in their 20% side-project time, Oppia provides an open-source engine for educators, tutors, or anyone really to easily create learning “explorations” on about any topic.

The ability and versatility in the framework behind these explorations makes Oppia ideal for guided inquiry. What really makes it special is the ability to script advanced feedback rules to guide the learner toward correct responses. Continue reading

# Learn the Cranial Nerves

## Store Your A&P’s Intercranially at Study Putty

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:
