3. Layers Upon Layers - Assessments


  1. Collect the labeled drawings and paragraphs.
  2. Provide your own drawing of a cup with layers and ask the students to describe the series of events that led to the formation of the cup, just as they did with their own cups.

Going Further

  1. Spend a day looking at photographs of rock layers in landscapes such as the Grand Canyon, Bryce Canyon, Petra, or other places with amazing rock layers. Teach about the formation of these places or have students independently research them.
  2. Go on a field trip to look at rock layers and study the rock layers up close, making hypotheses about the depositional environments that formed each layer and the sequence of events that must have taken place. See the Caldecott Tunnel field trip description for an example.
