The number of stars that can be seen through telescopes is dramatically greater than can be seen by the unaided eye. Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept, and to address the content the other three strands, students should develop their own questions and perform investigations. The properties of rocks and minerals reflect the processes that formed them. Waves, wind, water, and ice shape and reshape the Earth's land surface.

Water on Earth moves between the oceans and land through the processes of evaporation and condensation. Energy from the sun heats the Earth unevenly, causing air movements resulting in changing weather patterns. The solar system consists of planets and other bodies that orbit the sun in predictable paths. Scientific progress is made by asking meaningful questions and conducting careful investigations.
