This is a visually appealing 59 slide powerpoint with great pictures and embedded videos. There are quiz questions after each section of slides.
Slides 1- 54 are about plate tectonics and layers of the earth. Layers of the earth is brief. It gives a history of how we know they're there as well as what each layer is.
I've included the beginning of a heat transfer lesson at the end (slides 55-59).
This powerpoint took about 4 days to get through, along with interactive notebook activities that we completed at certain spots in the powerpoint.
