Description
Grades 2-4. In Rocks and Minerals, students are asked to explore the differences between rocks and minerals by observing the properties of rock samples, and sorting them based on those properties. Students also investigate minerals, on which they perform tests similar to those conducted by geologists to determine luster, hardness, color, and ability to transmit light, strengthening their ability to conduct experiments and record and interpret their data.

Students also investigate minerals, on which they perform tests similar to those conducted by geologists to determine luster, hardness, color, and ability to transmit light, strengthening their ability to conduct experiments and record and interpret their data. Students compile a Mineral Field Guide, which is the sum total of their observations and discoveries. They use this field guide and their new knowledge of rocks and minerals to identify several unknown samples at the end of the unit. Throughout Rocks and Minerals, students read about different minerals and how they are used. Students continue to practice recording data and interpreting their scientific findings to draw conclusions based on evidence.
