About This Lesson
The 'weathering cards' slide 1 needs to be cut out and laminated (2 copies) and then spread around the classroom. Students have a copy of slide 2 and they find relevant card and answer questions on it. Answers can then be discussed (slide 3).
Alternatively - give students worksheet (slide 2) and then show the images on the 'weathering powerpoint'.
A good selection of photographs in this PowerPoint each slide contains an explanation of how why the weathering occured.
