A look at the earth

TeachersFirst recently shared a series of Earth Science resources including Dynamic Interactive Earth.    It is geared for grades 4-9.  Here’s a brief review from TeachersFirst:

Learn the powerful forces that shape and change the Earth. Dynamic Earth explores the Earth's Structures, Investigating Plate Tectonics, learning about Plates and Boundaries, and how the plates Slip, Slide, and Collide. Read the information provided, click on the Interactive pictures for more details, and test your knowledge in each section with interactive activities. In the end, test your skills using an online assessment.
