II.I.II: Know that energy is needed to get things done and that energy has different forms.
II.I.II.1: Understand that light is a form of energy and can travel through a vacuum.
II.I.II.2: Know that light travels in a straight line until it strikes an object and then it is reflected, refracted, or absorbed.
II.I.II.4: Construct charts or diagrams that relate variables associated with energy changes (e.g., melting of ice over time).
II.I.III: Identify forces and describe the motion of objects.
II.I.III.1: Recognize that magnets can produce motion by attracting some materials (e.g., steel) and have no effect on others (e.g., plastics).
II.I.III.2: Describe how magnets have poles (N and S) and that like poles repel each other while unlike poles attract.
II.II.I: Know that living things have diverse forms, structures, functions, and habitats.
II.II.I.2: Observe that plants and animals have structures that serve different functions (e.g., shape of animals' teeth).
II.III.I: Know the structure of the solar system and the objects in the universe.
II.III.I.1: Describe the objects in the solar system (e.g., sun, Earth and other planets, moon) and their features (e.g., size, temperature).
II.III.I.2: Describe the relationships among the objects in the solar system (e.g., relative distances, orbital motions).
II.III.II: Know the structure and formation of Earth and its atmosphere and the processes that shape them.
II.III.II.4: Identify how water exists in the air in different forms (e.g., in clouds and fog as tiny droplets; in rain, snow, and hail) and changes from one form to another through various processes (e.g., freezing/condensation, precipitation, evaporation).
