A challenging worksheet focusing on 'Earth's Story' and what order things first appeared on Earth. This was used as an introductory lesson in Year 7 Geography; however, it could certainly be incorporated into Science SOW on Evolution, or as an introductory History lesson on chronology! The first half of the worksheet is relatively straightforward; however, some students may need supporting with the final question (Earth's story as a 24hr clock) as it is a tricky concept for some to get their heads around.

Brief PowerPoint presentation on geological time to be used alongside the Geog.1 text book for Year 7 pupils (although, it could be adapted for a Science lesson on evolution). Students are asked to define 'eon' and 'era' and use their traffic light pages in their planners to answer questions on a timeline digram (found in the text book). I've also included a lesson plan.
