"... both the River has changed, and so has the Person." - Heraclitus
Our 3rd Graders just wrapped up a Project Lead The Way unit on "The Changing Earth". We studied different soil types in color, texture, size, and how well they drained water. We also experimented with our stream tables to watch the process of erosion, and brainstormed ways we could slow down that process. We needed to design a model that would prevent a landslide in the stream table from destroying houses (wooden blocks) at the bottom of a hill.
