explain how different levels of sound are used in everyday life such as a whisper in a classroom or a fire alarm; and
A student expectation is directly related to the knowledge and skills statement, is more specific about how students demonstrate their learning, and always begins with a verb. Student expectations are further broken down into their component parts, often referred to as “breakouts.”
Vertical alignment shows student expectations in the same subject area at different grade levels that are related to or build upon one another.
demonstrate and explain that sound is made by vibrating matter and that vibrations can be caused by a variety of means, including sound;
explain how different levels of sound are used in everyday life such as a whisper in a classroom or a fire alarm; and
design and build a device using tools and materials that uses sound to solve the problem of communicating over a distance.
identify everyday examples of energy, including light, sound, thermal, and mechanical; and
Breakouts are the component parts that make up a student expectation. A breakout shows a distinct concept a student should know or a distinct skill that a student should be able to demonstrate.
Cause-and-effect relationships are relationships between two or more variables or phenomena whereby one variable or event leads to a predictable response. Events have causes—sometimes simple, sometimes multi-faceted.
Different levels of sound (effect) are needed to communicate in different situations (cause).
It is important to consider how changes in scale, proportion, or quantity affect a system’s structure or performance. Scale refers to the size of an object in relation to another object or its environment. Proportion is the ratio of one quantity to another. Quantity is a count of a set of objects or a measurement of a substance. It is important to note that in kindergarten – grade 2, students will only describe objects in terms of size (scale) and quantity.
Scale is used when comparing the level of the sound produced to the ambient noise level in the area. Increasing or decreasing the volume (quantity) changes the level of sound.
Stability describes a system that does not change at the observed scale. In a stable system, a small disturbance will die out and the system will return to a stable state. Change in the system can come from modifying a factor or condition.
Sound that is monotone is stable. Effective communication requires changes in pitch and volume based on the purpose of the communication.
