## Performance Expectations

The performance expectations in fourth grade help students formulate answers to questions such as:

• What are waves and what are some things they can do?
• How can water, ice, wind and vegetation change the land?
• What patterns of Earth’s features can be determined with the use of maps?
• How do internal and external structures support the survival, growth, behavior, and reproduction of plants and animals?
• What is energy and how is it related to motion?
• How is energy transferred?
• How can energy be used to solve a problem?

Students are able to use a model of waves to describe patterns of waves in terms of amplitude and wavelength, and that waves can cause objects to move. Students are expected to develop understanding of the effects of weathering or the rate of erosion by water, ice, wind, or vegetation. They apply their knowledge of natural Earth processes to generate and compare multiple solutions to reduce the impacts of such processes on humans. In order to describe patterns of Earth’s features, students analyze and interpret data from maps. Fourth graders are expected to develop an understanding that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction. By developing a model, they describe that an object can be seen when light reflected from its surface enters the eye. Students are able to use evidence to construct an explanation of the relationship between the speed of an object and the energy of that object. Students are expected to develop an understanding that energy can be transferred from place to place by sound, light, heat, and electric currents or from object to object through collisions. They apply their understanding of energy to design, test, and refine a device that converts energy from one form to another.

## Calculation Method for DCI

Disciplinary Core Ideas are larger groups of related Performance Expectations. So the Disciplinary Core Idea Grade is a calculation of all the related Performance Expectations. So click on the Performance Expectation name below each Disciplinary Core Idea to access the learning targets and proficiency scales for each Disciplinary Core Idea's related Performance Expectations.

#### SCI-04.PS3.01

[PS3] Energy

##### SCI-04.PS3.01 Use evidence to construct an explanation relating the speed of an object to the energy of that object.

Clarification Statement: Emphasis on relative speeds of objects and the connection between motion and energy
Disciplinary Core Ideas
The faster a given object is moving, the more energy it possesses.

#### SCI-04.PS3.02

[PS3] Energy

##### SCI-04.PS3.02 Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.

Clarification Statement: Emphasis on the transfer of energy whenever objects are moving. Examples of how sound, light, and heat can transfer energy.
Disciplinary Core Ideas
Energy can be transferred from place to place by moving objects or through sound, light, or electric currents.
Energy is present whenever there are moving objects, sound, light, or heat. When objects collide, energy can be transferred, thereby changing their motion. In such collisions, some energy is typically also transferred to the surrounding air; as a result, the air gets heated and sound is produced.
Energy can also be transferred from place to place by electric currents, which can be used to produce motion, sound, heat, or light. The currents may have been produced to begin with by transforming the energy of motion into electrical energy

#### SCI-04.PS3.03

[PS3] Energy

##### SCI-04.PS3.03 Ask questions and predict outcomes about the changes in energy that occur when objects collide.

Clarification Statement: Emphasis is on the change in the energy due to the change in speed, not on the forces, as objects interact.
Disciplinary Core Ideas
Energy can be moved from place to place by moving objects or through sound, light, or electric currents.
Energy is present whenever there are moving objects, sound, light, or heat. When objects collide, energy can be transferred from one object to another, thereby changing their motion. In such collisions, some energy is typically also transferred to the surrounding air; as a result, the air gets heated and sound is produced.
When objects collide, the contact forces transfer energy so as to change the objects’ motions.

#### SCI-04.PS3.04

[PS3] Energy

##### SCI-04.PS3.04 Using the engineering design process build a device that converts energy from one form to another.

Clarification Statement: Examples of devices could include a greenhouse model such as a glass jar in direct sunlight, electric circuits that convert electrical energy into motion energy of a vehicle, light, or sound; and, a passive solar heater (solar oven) that converts light into heat. Examples of constraints could include the materials, cost, or time to design the device. Use engineering design process flow chart.
Disciplinary Core Ideas
Energy can also be transferred from place to place by electric currents, which can be used to produce motion, sound, heat, or light.
The success of a designed solution is determined by considering the desired features of a solution (criteria). Different proposals for solutions can be compared on the basis of how well each one meets the specified criteria for success or how well each takes the constraints into account. (secondary)

#### SCI-04.PS4.01

[PS4] Waves and Their Applications in Technologies for Information Transfer

##### SCI-04.PS4.01 Develop a model of waves to describe patterns in terms of amplitude and wavelength and that waves can cause objects to move.

Clarification Statement: Examples of models could include diagrams, analogies, and physical models using wire to illustrate wavelength and amplitude of waves.
Disciplinary Core Ideas
Waves, which are regular patterns of motion, can be made in water by disturbing the surface. When waves move across the surface of deep water, the water goes up and down in place; there is no net motion in the direction of the wave except when the water meets a beach.
Waves of the same type can differ in amplitude (height of the wave) and wavelength (spacing between wave peaks)
