The Geological Society of America (GSA) offers lessons plans and additional resources covering virtually all topics in geology for K-12 students. The materials are divided into 12 topics, such as Environmental Science, Weather and Climate, and Plate Tectonics. Each of the topics has elementary, intermediate, and secondary lesson plans that offer details on the content, time required, materials needed, and directions for the project. The stimulating activities are a great way for students to understand otherwise difficult subjects and excite them about geology.
