Following our cheat sheets for common polyatomic ions, acids, and bases, here is one for organic chem: a study sheet for hydrocarbons, in particular the first 10 straight-chained alkanes.
Alkanes, the Simplest of Hydrocarbons
In addition to the image or PDF below, you can study the same material in our memorization web app, Study Putty, for absolutely free. Study Putty is in public beta. Try it out here.

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:
Amino Acid R Groups (Match proteins to their side chains) Continue reading
“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
Like our polyatomic ion study sheet, the acids and bases list gives the names and formulae for common substances you may need to memorize for chemistry class.

A New Chemistry Study Tool
The Stud: Hearts melt like putty in his charming arms. Well, actually he melts like putty because he is.
Master the following at Study Putty:
- The Elements
- Common Polyatomic Ions
- Acid Nomenclature
- Base Nomenclature
- The First Ten Straight-Chained Hydrocarbons
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.

We offer two free resources to study polyatomic ions.
A Polyatomic Ion List
Sometimes when it comes to studying, simple is best. This polyatomic ion table can be used as a classroom handout or for self study. It can be viewed online or printed. If printed out, it can be neatly folded in half so only the names or the formulas (with charges) can be seen.
We’ve made a downloadable PDF version, and also a webpage version of the polyatomic ions list. Continue reading
Free Graphing Calculator for iOS © William Jockusch. This screenshot is believed to be fair use because 1) it is low-res, and 2) it is used for the purpose of review.
One Free Calculator to Rule Them All
Developer William Jockusch describes his Free Graphing Calculator app with a bold claim: “Does far more than most of the paid calculators out there…let alone the free ones.” Given a few minutes to explore the app on an iPad, I was made a believer. The functionality and amount of data that have been put into Free Graphing Calculator are almost amazing.
To begin, we have access to almost everything a high school student or college undergrad would need in an expensive TI, but for free: basic calculator; graphing equations; linear, quadratic, and cubic equations solvers…But to stop there, that would be too easy.
The app includes a reference directory with categories for algebra, calculus, trigonometry, et cetera. It has most of the basic mathematical disciplines you could think of, with entries like “definition of a derivative” and “simplifying fractions.” There are also references for classical mechanics and logic.
High school and college students have a number of free apps available to help with chemistry class. After browsing the App Store I selected two periodic table apps that were free, high quality, and which seemed efficacious for learning. These selections can aid a student who is rehearsing the elements for an exam, or anybody who would like to be more familiar with the periodic table. Continue reading
