Here is a semantic map for rock types that can be used in classrooms to provide students a conceptual system of the knowledge they have gained by learning a science topic involving rocks. The map visually represents the textual knowledge to help young students better memorize the concepts. It can also be used as a strategy for learning science, science vocabulary learning models, and pre-and post-reading after reading a topic involving different rocks.
The semantic maps help the students understand how concepts or words are related to each other. In this map, there are three different rock types, sedimentary, igneous, and metamorphic. These are further divided into clastics, non-clastics, intrusive, extrusive, high temperature, and low temperature. As compared to texts, this visual representation is more effective in helping students understand and remember the scientific concepts.
