NGSS.2-ESS. EARTH AND SPACE SCIENCE

2-ESS1. Earth’s Place in the Universe - Students who demonstrate understanding can:

2-ESS1-1. Make observations from media to construct an evidence-based account that Earth events can occur quickly or slowly.

2-ESS2. Earth’s Systems - Students who demonstrate understanding can:

2-ESS2-2. Develop a model to represent the shapes and kinds of land and bodies of water in an area.
2-ESS2-3. Obtain information to identify where water is found on Earth and that it can be solid or liquid.
2-ESS2.CNS. Connections to Nature of Science
2-ESS2.CNS.1. Science Addresses Questions About the Natural and Material World
2-ESS2.CNS.1.1. Scientists study the natural and material world.

NGSS.2-LS. LIFE SCIENCE

2-LS2. Ecosystems: Interactions, Energy, and Dynamics - Students who demonstrate understanding can:

2-LS2-1. Plan and conduct an investigation to determine if plants need sunlight and water to grow.
2-LS2.CC. Crosscutting Concepts
2-LS2.CC.2. Structure and Function
2-LS2.CC.2.1. The shape and stability of structures of natural and designed objects are related to their function(s).
2-LS2.DCI. Disciplinary Core Ideas
LS2.A: Interdependent Relationships in Ecosystems
LS2.A:1. Plants depend on water and light to grow. (2-LS2-1)

2-LS4. Biological Evolution: Unity and Diversity - Students who demonstrate understanding can:

2-LS4-1. Make observations of plants and animals to compare the diversity of life in different habitats [Assessment Boundary: Assessment does not include specific animal and plant names in specific habitats.]
2-LS4.DCI. Disciplinary Core Ideas
LS4.D: Biodiversity and Humans
LS4.D:1. There are many different kinds of living things in any area, and they exist in different places on land and in water. (2-LS4-1)

NGSS.2-PS. PHYSICAL SCIENCE

2-PS1. Matter and its Interactions - Students who demonstrate understanding can:

2-PS1-4. Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot.
2-PS1.CC. Crosscutting Concepts
2-PS1.CC.3. Energy and Matter
2-PS1.CC.3.1. Objects may break into smaller pieces and be put together into larger pieces, or change shapes.
2-PS1.DCI. Disciplinary Core Ideas
PS1.A: Structure and Properties of Matter
PS1.A:1. Different kinds of matter exist and many of them can be either solid or liquid, depending on temperature. Matter can be described and classified by its observable properties. (2-PS1-1)PS1.A:3. A great variety of objects can be built up from a small set of pieces. (2-PS1-3)
