S.T.E.M. learning resources for geology make it possible to engage the hands-on and the visual learner. Understanding what is going on inside the Earth is easier to explain, and for the student easier to understand, if a model is used. The good news is models are easy to find. However, care must be taken if one is to stay within a budget.
For quality models, handling by a child is not likely to destroy them. Many are made to be durable.
Another positive is models can be reused. So, if a student is one of several who will need to complete an Earth study, the models can be used over and over. Or, for homeschool applications, if a group joins together and cover the material at different times, or concurrently as a group, the cost can be spread making models even more attractive. Then they can be passed on to another group of students.
