communicate the idea that objects can only be seen when a light source is present and compare the effects of different amounts of light on the appearance of objects; 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.
communicate the idea that objects can only be seen when a light source is present and compare the effects of different amounts of light on the appearance of objects; and
demonstrate and explain that light travels through some objects and is blocked by other objects, creating shadows.
identify everyday examples of energy, including light, sound, thermal, and mechanical; and
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.
When light shines on an object (cause), it can be seen (effect). When the amount of light changes (cause), the appearance of an object might change (effect) but the object itself will not change.
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.
Consider a system which contains light sources, an object, and an observer. When different amounts of light are shone on an object, the change in the amount of light changes the observer's perception of the object.
