demonstrate and explain that sound is made by vibrating matter and that vibrations can be caused by a variety of means, including sound;
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.
Sound is created (effect) when an object vibrates (cause).
Energy flows within a system or between systems through transfers and transformations. Matter is cycled within systems through physical and chemical processes. It is important to note that in kindergarten – grade 2, the foundation of flow of energy and cycling of matter is built by identifying the forms of energy and properties of matter. In grades 3–8, students learn that matter and energy are conserved, changing forms but maintaining quantities.
Energy flows within a system. The system comprises the instrument or object vibrating, like a guitar or tuning fork, and the medium (air, a liquid, or a solid) through which the vibrations travel to the ear. Energy is transferred to the instrument, making it vibrate, and then the energy travels through the medium to the ear.
