    • S4.D.2.1 Identify basic weather conditions and how they are measured.

      • S4.D.2.1.1 Identify basic cloud types (i.e., cirrus, cumulus, stratus, and cumulonimbus) and make connections to basic elements of weather (e.g., changes in temperature, precipitation).

      • S4.D.2.1.2 Identify weather patterns from data charts or graphs of the data (e.g., temperature, wind direction, wind speed, cloud types, precipitation).

      • S4.D.2.1.3 Identify appropriate instruments (i.e., thermometer, rain gauge, weather vane, anemometer, and barometer) to study weather and what they measure.

  • S4.D.3 Composition and Structure of the Universe

    • S4.D.3.1 Describe Earth's relationship to the Sun and the Moon.

      • S4.D.3.1.1 Describe motions of the Sun - Earth - Moon system.

      • S4.D.3.1.2 Explain how the motion of the Sun - Earth - Moon system relates to time (e.g., days, months, years).

      • S4.D.3.1.3 Describe the causes of seasonal change as they relate to the revolution of Earth and the tilt of Earth's axis.
