Thanks to television and movies, children's perception of when the dinosaurs were alive and what animals interacted with them is skewed. This is a powerpoint that starts at the beginning of Earth's time and goes through each period. It shows the evolution of life and how animals changed through time. Each slide has animations and pictures of the types of animals that were alive during each period.
I use this as an introduction to my dinosaur unit. It is fascinating to see the progression of life and how different life on earth used to be. It also develops a good understanding of how far apart in time the humans, mammoths, saber tooth tigers, and dinosaurs were. Children enjoy the colorful pictures and it really opens up their mind and prepares them to learn more about dinosaurs.
A reflection sheet is also included with the powerpoint.
I hope your students enjoy it as much as mine do!
