Community reviews for Earth Primer

As a teacher, I really valued that the animation continued even while the students were not actively involved in manipulating it. This gave them a real idea of what's happening to the crust over time. Especially for something you can't see, even if you were on a field trip, this was a fantastic tool for making science real for my students. For some of my students, it was very easy for them to use because of how engaging it was. For others, the amount of text was a bit cumbersome. They REALLY enjoyed the sandbox opportunities at the end of the text, which has helped set the stage for cause and effect conversations for our middle school science lab time. One thing I wish was a little better was the amount of time that lapses and the rate that weather systems or wildlife grows or dies within the sandbox feature. Things move so quickly that some students missed some of the phases of growth or destruction.
