Slides for a lesson covering natural selection and evolution (the Natural selection slides were for a Y10 lesson). The word document contains images used for an activity on human evolution. 4 groups are given each set of data (images of skulls, tools, brain size data and fossil age data) and have to decide in what order they evolved. Then rearrange the groups to share the data and then come up with a definitive order of evolution. Good for initiating discussion and employing critical thinking.
