The more we all know about energy, the better, say Paul Riehemann on his blog, Solve 4 Biggies:
Facts and information rule. Check out this article on Grinning Planet. It lists (and links to) nine quizzes on energy topics in order of overall quality. The difficultly level (1 - 10) for each quiz is listed as well as comments. For example, "A bit Brit, but a very nicely done energy quiz, with informative pop-ups and some fun things for you to get sidetracked by."Enjoy.....and learn. I did (would have liked to score higher on a couple though....)
Pass it on!
