EARTH’S PLACE IN THE UNIVERSE

EARTH’S SYSTEMS

Use data to describe different kinds of materials by their observable properties (e.g., color, texture).

Use data to classify different kinds of materials by their observable properties (e.g., color, texture).

Match a property of a material (e.g., hard, flexible, absorbent) to a potential purpose (e.g., hardness of a wooden shelf results in it being better suited for supporting materials than a soft sponge).

Identify how a variety of objects can be built up from a small set of pieces.

Identify examples of heating substances which cause changes that are sometimes reversible and sometimes not.

Identify examples of cooling substances which cause changes that are sometimes reversible and sometimes not.

Use data to describe that plants need water and light to grow.

Identify that plants need animals to move their seeds around.

Identify a simple model that mimics the function of an animal in dispersing seeds or pollinating plants.

Make observations to explain that different kinds of living things live in different habitats on land and in water.

Use evidence to understand that some Earth events happen quickly and can be observed (e.g., flood, volcano eruption, earthquake, or erosion of soil).

Use evidence to understand that some Earth events happen slowly (e.g., erosion or weathering of rocks).

Identify a solution (e.g., using shrubs, grass, or trees) to slow or prevent wind from changing the shape of the land.

Identify a solution (e.g., using shrubs, grass, or trees) to slow or prevent water from changing the shape of the land.

Use a model to Identify land features and bodies of water (e.g., hill, lake) in an area using a model.

Use information to identify that water is found in many types of places.

Use information to identify that that water exists as solid ice and in liquid form.
