ESS Earth and Space Science

The Atmosphere
- 2.ESS.1 The atmosphere is primarily made up of air.
  - 2.ESS.1.a Air has properties that can be observed and measured. The transfer of energy in the atmosphere causes air movement, which is felt as wind. Wind speed and direction can be measured.
- 2.ESS.2 Water is present in the atmosphere.
  - 2.ESS.2.a Water is present in the atmosphere as water vapor. When water vapor in the atmosphere cools, it forms clouds, fog, rain, ice, snow, sleet or hail.
- 2.ESS.3 Long- and short-term weather changes occur due to changes in energy.
  - 2.ESS.3.a Changes in energy affect all aspects of weather, including temperature, precipitation, and wind.

PS Physical Science

Changes in Motion
- 2.PS.1 Forces change the motion of an object.
  - 2.PS.1.a Motion can increase, change direction or stop depending on the force applied.
    - Identify pushes and pulls (2-G.1)
    - How do mass and force affect motion? (2-G.2)
  - 2.PS.1.b The change in motion of an object is related to the size of the force.
    - Identify pushes and pulls (2-G.1)
    - How do mass and force affect motion? (2-G.2)
  - 2.PS.1.c Some forces act without touching, such as using a magnet to move an object or objects falling to the ground.
    - Identify magnets that attract or repel (2-H.1)
    - Label magnets that attract or repel (2-H.2)

LS Life Science

Interactions within Habitats
- 2.LS.1 Living things cause changes on Earth.
  - 2.LS.1.a Living things function and interact with their physical environments. Living things cause changes in the environments where they live; the changes can be very noticeable or slightly noticeable, fast or slow.
- 2.LS.2 All organisms alive today result from their ancestors, some of which may be extinct. Not all kinds of organisms that lived in the past are represented by living organisms today.
  - 2.LS.2.a Some kinds of organisms become extinct when their basic needs are no longer met or the environment changes.
