Physical Science (EE.5-PS)

Matter and Its Interactions (EE.5-PS1)


Target Level: Measure and compare weights of substances before and after heating, cooling, or mixing substances to show that weight of matter is conserved.

Precursor Level: Compare the weight of an object before and after it changes from a liquid to a solid and from a solid to a liquid.

Initial Level: Recognize the change in state from liquid to solid or from solid to liquid of the same material.


Target Level: Make observations and measurements to identify materials based on their properties (e.g., weight, shape, texture, buoyancy, color, or magnetism).

Precursor Level: Classify materials by physical properties (e.g., weight shape, texture, buoyancy, color, or magnetism).

Initial Level: Match materials with similar physical properties.

Motion and Stability: Forces and Interactions (EE.5-PS2)


Target Level: Demonstrate that the gravitational force exerted by Earth on objects is directed down.

Precursor Level: Predict the direction an object will go when dropped.

Initial Level: Recognize the direction an object will go when dropped.

Energy (EE.5-PS3)


Target Level: Create a model to describe that energy in animals' food was once energy from the Sun.

Precursor Level: Use models to describe that plants capture energy from sunlight.

Initial Level: Identify simple models that show that plants need sunlight to grow.

Life Science (EE.5-LS)

From Molecules to Organisms: Structures and Processes (EE.5-LS1)


Target Level: Provide evidence that plants need air and water to grow.

Precursor Level: Provide evidence that plants grow.

Initial Level: Distinguish things that grow from things that don't grow.

Ecosystems: Interactions, Energy, and Dynamics (EE.5-LS2)


Target Level: Create a model that shows the movement of matter (e.g. plant growth, eating, composting) through living things.

Precursor Level: Identify a model that shows the movement of matter from plants to animals (e.g. food chain/food web).

Initial Level: Identify common human foods.

Earth and Space Sciences (EE.5-ESS)

Earth's Place in the Universe (EE.5-ESS1)


Target Level: Represent and interpret data on a picture, line, or bar graph to show seasonal patterns in the length of daylight hours.

Precursor Level: Recognize patterns about length of daylight hours over time (e.g., week to week, month to month).

Initial Level: Order events in daily routines including sunrise and sunset.

Earth's Systems (EE.5-ESS2)


Target Level: Develop a model showing how water (hydrosphere) affects the living things (biosphere) found in the region.

Precursor Level: Recognize how water (hydrosphere) affects the living things (biosphere) in a region.

Initial Level: Anticipates routine (e.g., clothes to wear, activities to do) to follow when it is raining.

Earth and Human Activity (EE.5-ESS3)


Target Level: Use information to describe how people can help protect the Earth's resources and how that affects the environment.

Precursor Level: Compare two methods that people can use to help protect the Earth's resources.

Initial Level: Identify one way to protect a resource of Earth (e.g., put paper in the recycling bin).
