3rd Nine Weeks Expectations
Science
- SC-04-1.1.1 Students will explain how matter, including water, can be changed from one state to another.
Materials can exist in different states-solid, liquid, and gas. Some common materials, such as water, can be changed from one state to another by heating or cooling. Resulting cause and effect relationships should be explored, described and predicted. DOK 3
- SC-04-1.2.1 Students will interpret or represent data related to an object’s straight-line motion in order to make inferences and predictions of changes in position and/or time.
An object’s motion can be described by measuring its changes in position over time such as rolling different objects (e.g., spheres, toy cars) down a ramp. Collecting and representing data related to an object’s motion provides the opportunity to make comparisons and draw conclusions. DOK 3
- SC-04-1.2.2 Students will infer causes and effects of pushes and pulls (forces) on objects based on representations or interpretations of straight-line movement/motion in charts, graphs, and qualitative comparisons.
The position and motion of objects can be changed by pushing or pulling. The amount of change is related to the force (defined as the strength of the push or pull) and the mass of the object(s) used. The force with which a ball is hit illustrates this principle. Cause and effect relationships, along with predicted consequences related to the strength of pushes and pulls (force) on an object’s position and motion should be explored and qualitatively compared. DOK 3
- SC-04-1.2.3 Students will explain that sound is a result of vibrations, a type of motion; describe pitch (high, low) as a difference in sounds that are produced and relate that to the rate of vibration.
Vibration is a type of motion that can be observed, described, measured and compared. Sound is produced by vibrating objects. The pitch of the sound can be varied by changing the rate of vibration. The relationship between rates of vibration and produced sounds can be described and graphed. DOK 3

- SC-04-4.6.3
Students will evaluate a variety of models/representations of electrical circuits (open, closed, series and/or parallel) to: make predictions related to changes in the system; compare the properties of conducting and non-conducting materials.
Electricity in circuits can produce light, heat and sound. Electrical circuits require a complete conducting path through which an electrical current can pass. Analysis of a variety of circuit models creates an opportunity to make predictions about circuits, as well as to demonstrate an understanding of the concepts of open and closed circuits and basic conducting and non-conducting materials. DOK 3
- SC-04-4.6.4 Students will analyze models/representations of light in order to generalize about the behavior of light. Students will represent the path of light as it interacts with a variety of surfaces (reflecting, refracting, absorbing).
Light can be observed as traveling in a straight line until it strikes an object. Light can be reflected by a shiny object (e.g., mirror, spoon), refracted by a lens (e.g., magnifying glass, eyeglasses) or absorbed by an object (e.g., dark surface). Questions posed about the behavior and interaction of light with a variety of surfaces, can be explored through investigations using simple equipment. DOK 3
- SC-04-4.6.5 Students will identify ways that heat can be produced (e.g. burning, rubbing) and properties of materials that conduct heat better than others; describe the movement of heat between objects.
Heat can be produced in many ways such as burning or rubbing. Heat moves from a warmer object to a cooler one by contact (conduction) or at a distance. Some materials absorb and conduct heat better than others. Simple investigations can illustrate that metal objects conduct heat better than wooden objects. DOK 2
