S.ESS.2.1a

Explain how smaller rocks come from the breakage and weathering of larger rocks.

S.ESS.2.1b

Describe rocks in terms of their parts (e.g. crystals, grains, cement).

S.ESS.2.1c

Sort rocks based upon color, hardness, texture, layering, particle size and type (i.e. igneous, metamorphic, sedimentary).

S.ESS.2.2a

Observe, describe, and record patterns in the appearance and apparent motion of the moon in the night sky.

S.ESS.2.2b

Observe and describe the number, arrangement and color/brightness of stars in the night sky.

S.ESS.2.3a

Compare and contrast the seasonal weather patterns during the school year

S.ESS.2.3b

Analyze and interpret data such as temperatures in different locations and different times.

S.LS.4.1a

Compare and contrast the characteristics of living things in different habitats.

S.LS.4.1b

Develop, communicate, and justify an explanation as to why a habitat is or is not suitable for a specific organism.

S.LS.4.1c

Create possible explanations as to why some organisms no longer exist, but similar organisms are still alive today.

S.LS.4.2a

Communicate and justify how the physical characteristics of living things help them meet their basic needs.

S.LS.4.2b

Observe, record, and compare how the behaviors and reactions of living things help them meet their basic needs.

S.LS.4.2c

Identify behaviors and reactions of living things in response to changes in the environment including seasonal changes in temperature and precipitation.

S.NS.1.1a

Framing questions: Observe using senses, create a hypothesis, and focus a question that can lead to an investigation.

S.NS.1.1b

Designing investigations: Consider reasons that support ideas, identify ways to gather information that could test ideas, design fair tests, share designs with peers for input and refinement.

S.NS.1.1c

Conducting investigations: Observe, manipulate, measure, describe.

S.NS.1.1d

Collecting data: Deciding what data to collect and how to organize, record, and manipulate the data.

S.NS.1.1e

Drawing conclusions: Analyzing data, making conclusions connected to the data or the evidence gathered, identifying limitations or conclusions, identifying future questions to investigate.

S.NS.1.2a

Developing social interaction skills with peers.

S.NS.1.2b

Sharing ideas with peers.

S.NS.1.2c

Connecting ideas with reasons (evidence).

S.NS.1.2d

Using multiple methods of communicating reasons/evidence (verbal, charts, graphs).

S.NS.1.3a

Ideas are supported by reasons.

S.NS.1.3b

There are limits to ideas in science (i.e. what can be observed, measured, and verified).

S.NS.1.3c

Differences in conclusions are best settled through additional observations and investigations.

S.NS.1.3d

Communication of ideas in science is important for helping to check the reasons for ideas.

S.PS.3.1a

Observe falling objects and identify things that prevent them from reaching the ground.

S.PS.3.1b

Communicate observations that similar objects of varying masses fall at the same rate.

S.PS.3.2a

Model physical changes of various materials

S.PS.3.2b

Investigate and provide evidence that matter is not destroyed or created through changes.
