This took a loooong time to make, but it was totally worth it. Never before has there been a PowerPoint about continental drift and plate tectonics that is so straightforward and engaging, With dozens of original animations and illustrations, smooth transitions, and a healthy dose of humor scattered over 255 slides, your students are guaranteed to be engrossed. The PowerPoint is divided up into six major parts:
1. Alfred Wegener and Continental Drift
This portion covers Alfred's big idea of continental movement and the supercontinent of Pangaea. It also covers Alfred's major evidences.
2. Alfred's Rejection
This portion covers why Alfred was not accepted in his time and the difference between a hypothesis and a theory.
3. Harry Hess and Modern Evidence
This portion covers the discovery of mid-ocean ridges, Harry Hess, seafloor spreading, discovering the age of ocean rocks, and magnetic striping of the ocean floor.
4. Driving Forces of Plate Movement
This portion covers how convection, gravity, and pressure are moving the Earth's plates.
5. Plate Tectonics
This portion covers the modern theory of plate tectonics and the various layers of the Earth that are involved in plate movement.
6. Plate Boundaries
This portion covers convergent, divergent, and transform boundaries and what happens at each one (including the subcategories of convergent boundaries). It also covers hot spots.
Teaching this material in my own classroom typically takes around five class periods of fifty minutes each. I don't teach it all straight over five days because I like to break it up with other activities and assignments, but all in all it will take a good four to five days to cover well. Included with the PowerPoint is a slick looking student note sheet that students can be filling out as you go through the PowerPoint. I have included both a blank copy and a filled in version of the notes. Also included is a teacher's guide to help guide you in best using the PowerPoint in your own classroom.
I absolutely love this PowerPoint, and my students do to, but you don't have to take my word for it - download the free preview version now for a sneak peek. Just remember, the real deal is much larger and much more detailed, with over 250 slides.
Anyways, I hope that both you and your students enjoy your download and that it is helpful in your classroom. Please be sure to leave feedback so that others can know what a great product this is, and be sure to become a fan and follow me so that you can get information on future releases. Thanks!
Note: This PowerPoint uses the non-standard free font "AR Darling" quite extensively. It is free to download, so I definitely recommend that, but if you would prefer then feel free to go through and change the font to something that better suits your preferences.
