Science Learning Space. Geography From Space. 30 second science. After our strange, and still somewhat baffling, crayon candle experience, we decided to move on to a safer, tried and true, Steve Spangler recommended activity.
We had read on his site, that if you slowly lower an ordinary balloon... ...down over a candle flame... ...the latex will melt, and the balloon will pop, well before you reach the flame. That turned out to be true. Sorry for the blurry picture, but the "pop" was surprisingly loud. Mr. I'm not sure our water was really boiling. ...what would happen if we used the sun's heat, focused through a magnifying glass, instead of a candle flame. D volunteered to give it a try, while I attempted to photograph his efforts.
I wanted him to try again, so I could see for myself (and try for a picture), but he was shell shocked, and ready to move on to the safer, and quieter, water balloon. We timed out five minutes of burning time on the balloon, keeping the light beam as fixed as possible.

Holland A population of zebras surprised biologists by making a more than 300-mile beeline across parts of Namibia and Botswana—the longest big-mammal migration ever documented in Africa. In the wilds of Africa, food and water come and go with the seasons, and animals follow. The Serengeti is the site of what most consider the most dramatic migration, with giant herds of millions of animals—some 750,000 zebras and 1.2 million wildebeests as well as gazelles and eland—traveling from the Ngorongoro area in southern Tanzania to the Masai Mara in lower Kenya and returning as the rains dictate. But when it comes to the longest hike endpoint to endpoint, Africa has a new record holder. Straight Shot "The almost unerring north-south direction was unusual," says lead author Robin Naidoo, senior conservation scientist at the World Wildlife Fund (WWF). That the animals were migrating with the rains wasn't in itself surprising. Taking Detours.

What science books ought a bookstore stock? I have a little metric for rationality that I exercise now and then: when I visit a bookstore, I compare the sizes of the religion/new age sections to the size of the science section…if I can find it.
Typically, there’s at least a 10:1 disparity in the amount of shelf space dedicated, and it’s often much worse — there have been a few bookstores where, when I ask to find the science books, the clerk will point me to a small shelf labeled “Pets/Nature”. Bleh. Anyway, I got a good question on Saturday at Guelph, which also mentioned this cluelessness by too many bookstores. Could we compile a list of excellent science books, that is, books that should appeal to the lay public, have some chance of commercial success, and that we think do a good job of presenting an interesting and accurate view of science? I suspect there are a few people here who read books, and might have some opinions here — how about expressing them in the comments?
