This week in Science!

This week in science, we began our landforms investigations.  Students set up stream tables with "earth material" (a mixture of diatomaceous earth and sand) and a water source.  They ran a liter of water through the system and observed and recorded the processes of erosion and deposition.  They learned some of the vocabulary used to describe landforms that result from these processes.  The erosion observed in the stream table is related to the formation of the Grand Canyon.  In addition to our stream tables, we took a short field trip around the Allen Academy grounds to identify erosion.
