P Physical Science

Forces and Motion
- NCES.2.P.1 Understand the relationship between sound and vibrating objects.
  - NCES.2.P.1.1 Illustrate how sound is produced by vibrating objects and columns of air.
  - NCES.2.P.1.2 Summarize the relationship between sound and objects of the body that vibrate – eardrum and vocal cords.
Matter: Properties and Change
- NCES.2.P.2 Understand properties of solids and liquids and the changes they undergo.
  - NCES.2.P.2.1 Give examples of matter that change from a solid to a liquid and from a liquid to a solid by heating and cooling.
  - NCES.2.P.2.2 Compare the amount (volume and weight) of water in a container before and after freezing.
  - NCES.2.P.2.3 Compare what happens to water left in an open container over time as to water left in a closed container.

E Earth and Space Science

Earth Systems, Structures and Processes
- NCES.2.E.1 Understand patterns of weather and factors that affect weather.
  - NCES.2.E.1.1 Summarize how energy from the sun serves as a source of light that warms the land, air and water.
  - NCES.2.E.1.2 Summarize weather conditions using qualitative and quantitative measures to describe: temperature; wind direction; wind speed; and precipitation.
    - Read a thermometer (2-N.1)
    - Compare temperatures on thermometers (2-N.2)
  - NCES.2.E.1.3 Compare weather patterns that occur over time and relate observable patterns to time of day and time of year.
  - NCES.2.E.1.4 Recognize the tools that scientists use for observing, recording, and predicting weather changes from day to day and during the seasons.

L Life Science

Structures and Functions of Living Organisms
- NCES.2.L.1 Understand animal life cycles.
  - NCES.2.L.1.1 Summarize the life cycle of animals: birth; developing into an adult; reproducing; and aging and death.
    - Read animal life cycle diagrams (2-J.1)
    - Construct animal life cycle diagrams (2-J.2)
  - NCES.2.L.1.2 Compare life cycles of different animals such as, but not limited to, mealworms, ladybugs, crickets, guppies or frogs.
    - Compare different animals' life cycles (2-J.3)
Evolution and Genetics
- NCES.2.L.2 Remember that organisms differ from or are similar to their parents based on the characteristics of the organism.
  - NCES.2.L.2.1 Identify ways in which many plants and animals closely resemble their parents in observed appearance and ways they are different.
    - Match animals to their parents (2)
    - Match plants to their parents (2)
  - NCES.2.L.2.2 Recognize that there is variation among individuals that are related.
