Instructional time will focus on three critical areas. In Earth and Space science, students will focus on Earth's surface; identifying landforms and changes due to weathering, erosion, and deposition. In Physical Science, students will focus on electricity, heat, and matter; describing that the total amount of matter is conserved and energy can be transformed from one form to another. In Life science, students will focus on Earth's living history; describing how changes in an environment affect organisms that live there and how fossils can be compared to present day organisms.
