Identify that moving objects contain energy.

Demonstrate that objects moving faster possess more energy than objects moving slower.

Identify examples of how energy can be moved from place to place (i.e., through sound or light traveling; by electrical currents; heat passing from one object to another).

Identify the change in energy or the change in objects’ motions when objects collide (e.g., speeds as objects interact, direction).

Relate an example that demonstrates that energy can be converted from one form to another form (e.g., electric circuits that convert electrical energy into light, motion, sound or heat).

Describe the properties of waves using a model (e.g., drawings, diagrams) to show amplitude (height) and wavelength.

Identify relationships involving wave amplitude, wavelength, and the motion of an object (e.g., when the amplitude increases, the object moves more).

Identify amplitude as a measure of energy in a wave.

Identify wavelength as the distance between a point on one wave and the identical point on the next wave.

Arrange a model to show that light can be seen when light reflected from its surface enters the eye.

Identify external macroscopic structures (e.g., bird beaks, eyes, feathers, roots, needles on a pine tree) that support growth, survival, behavior, and reproduction of organisms.

Identify internal structures (e.g., heart, muscles, bones) that support growth, survival, behavior, and reproduction of organisms.

Identify that sense receptors provide different kinds of information, which is processed by the brain.

Identify how animals use their sense receptors to respond to different types of information (e.g., sound, light, odor, temperature) in their surroundings with behaviors that help them survive.

Identify how animals use their memories to help them survive.

Identify rock formations that show how the Earth’s surface has changed over time (e.g., change following earthquakes).

Identify older fossils as being found in deeper, older rock layers.

Use data to compare differences in the shape of the land due to the effects of weathering or erosion.

Identify how living things affect the shape of the land.

Use maps to locate different land and water features of Earth.

Use maps to determine that earthquakes and volcanoes often occur along the boundaries between continents.

Identify how plants affect the environment (e.g., some have roots that can stabilize or destabilize the soil).

Identify how animals affect the environment (e.g., they disturb rocks, soil, and sediment; some build dams or nests).

Identify the origins of the natural sources humans use for energy and fuel.

Identify environmental effects associated with the use of a given energy resource.

Describe solutions to reduce the impact of a natural Earth process (e.g., earthquake, flood, volcanic activity) on humans.
