There's only one month left until school starts, and kids everywhere are trying to suck the marrow out of what's left of the summer. Actually, a lot of them are bored out of their minds and keeping their parents abreast of that boredom on an hourly basis. Breathe some life into their urban staycation with this backyard science kit. It encourages them to see oft-overlooked specimens with what sages call "beginners mind" and use them to, say, create a leaf pendant, make a sunprint and unearth backyard pigments to decorate their collection bag. I might buy one for myself. Grassrootsstore.com, $29.99.
