Here are two quick resources for teaching about continents and continental drift. First, from the San Diego Supercomputer Center we have this animation of continental drift. Press play, pause, and rewind to see how the continents fit together.
Below is a video that asks and tries to answer the questions, “what are continents?” and “how many continents are there?” The video proposes a handful of different ways to look at how we divide the world. The arguments can basically be broken down to cultural geography versus physical geography.
Applications for Education
The SDSC animation is a good visual tool to support a lesson on continents. The video above could challenge students to think about how we divide the world and difference between cultural and physical geography.
