However, I do pick things up. On the side of the road (awesome kid's play kitchen), out of a ditch (toy plane), out of someone's dumpster (okay, that was my husband and that was good stuff he found), and out in nature.
Kids love to collect stuff. I got each of my kids a flat, plastic bait box from Cabella's with the little compartments. We pick up shells, acorns, feathers, pretty much whatever neat little doo-dads we find. I also ran across this image from the Australian website HomeLife.com and loved the idea of collecting pictures or creating a scrapbook with drawings and pictures of nature.

Do you and your kids collect anything? Have you done any fun "nature projects" with the wee ones?
