Hard-working water

We have spent the better part of a year learning how we can do things for our waterways. Now we are learning about all the Work (capital W!) that waterways can do for us! This week we experimented with water wheels. Barbara set the challenge of designing an efficient water wheel.

Which design needs the least “water power” to lift a crayon?

Our science and social studies work are truly at an intersection now!

Waterwheels were used in colonial mills (sawmills, gristmills, and more). Windmills were some of the early technologies used by the Dutch (and other cultures) to accomplish large-scale projects. In the Netherlands, windmills actually did the work of draining swamps to turn them into usable, stable land. The earliest known drainage mill is from 1414!
