Start at the end; that's the way to improve children's plans for investigations. Strange as it may seem, there are times when beginning at the beginning of an investigation is not the best way to start things off.

This approach helps to alert them to possible pitfalls and thus to make more sensible decisions. (Contains 3 figures and 1 online resource.)
