Neat hands-on Earth Science 3D Paper Models and Toys activities for classroom or homeschool:
California Geological Survey (CGS) staff have scoured the Internet and compiled this linked list of free-to-download, 3D paper models and paper toys that are related to the Earth Sciences. We have listed over 250 paper models that can be cutout and assembled. Some might be suitable for class projects while others are just plain fun to assemble. The difficulty of assembly for each model is highly varied. The text and directions on some cutout sheets for some models are in Japanese, but this seemed to pose little problem in the actual assembly process for those of us who do not understand the language.
