This research delves into the emphasis on spatial and temporal scales of Earth and Space Science processes in K-8 science standards and textbooks. The study analyzes systematic coding and analysis techniques and explores how these concepts are portrayed in various educational materials. It also examines the implementation of NGSS crosscutting concepts in states with significant student populations like CA, FL, and TX.
