Did you know Band-Aids were invented by accident?! And that they weren't mass-produced until the Boy Scouts gave their seal of approval? 1920s cotton buyer Earle Dickson worked for Johnson & Johnson and had a klutzy wife who often cut herself.

Band-Aids were born, but Earle's bosses at the pharmaceutical giant weren't convinced, and it wasn't until the Boy Scouts of America tested Earle's prototype that this ubiquitous household staple was made available to the public. Soon Band-Aids were selling like hotcakes, and the rest is boo-boo history.

In winter the humpback whales migrate to warmer waters, just as some land animals move to warmer climates. The cycle begins again as they return to the northern waters in the spring. In fun, fanciful form, Ocean Seasons introduces plants and animals that are joined through the mix of seasons, food webs, and habitats beneath the waves. While set in the Pacific, similar changes occur in the Atlantic also. The "For Creative Minds" learning sections features and "Ocean Food Web Card Game."
