Explore the layered formation of sedimentary rocks using this lesson plan and set of downloadable activities for 11–14 year olds.

In this lesson, students draw, exchange and interpret annotated diagrams of layers of sedimentary rocks, suggesting a possible sequence of events which could have led to their formation. Peer assessment and critique based on these diagrams provides a strong stimulus for students to think creatively and focus their discussion.
