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.
How much wood could a woodchuck chuck if a woodchuck could chuck 15.5 kilograms per minute in an eight hour work day? Give answer in megatonnes.
Dimensional analysis is not the first thing Mr. Spock does when the Starship Enterprise accidentally travels into a new universe or timeline. That is not what we’re here to learn about today.
Unfortunately. Because that sounds interesting.
Instead, we have what is also commonly called “the factor-label method” and simply “unit conversion.” Dimensional analysis is the method that is used to get an answer in the correct units of measurement in problems relating to math, chemistry, and other physical sciences. At its most simple, it can be solving how many minutes are in two hours, or, on the more complex end, it can be finding how many moles there are in three cubic meters of argon.
So are you stuck on your homework? We’ve assembled a few resources to help you with the factor label method. Continue reading →
We’ve assembled an online set of tools for use by a teacher or tutor looking for high quality free resources, or by a student who needs a little math, physics, or chemistry homework help. The following resources have been selected by our editors as representing the best of what is offered freely on the Internet. Continue reading →
