Sedimentator

Sealed in a clear 1" diameter tube, sediments from fine clays to coarse gravels demonstrate the principles of deposition and layering. The coarse sediments layer almost immediately while finer particles may take several days to completely separate out in the water column. This unique demonstration tube can be used alone or with a stream table, sedimentary rock kit, or fossil kit. The sedimentator comes complete with a teacher's guide and student activity guide.
