plan and conduct a descriptive investigation to demonstrate how the strength of a push and pull changes an object's motion.
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.
plan and conduct a descriptive investigation that predicts how pushes and pulls can start, stop, or change the speed or direction of an object's motion.
plan and conduct a descriptive investigation to demonstrate how the strength of a push and pull changes an object's motion.
plan and conduct a descriptive investigation to demonstrate and explain how position and motion can be changed by pushing and pulling objects such as swings, balls, and wagons.
Patterns are regular sequences that can be found throughout nature.
Patterns of change in an object's motion form based on the amount of force applied.
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.
As the strength of a push or pull is changed (cause), an object's motion changes (effect).
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.
The strength of the push or pull is a quantity on a relative scale.
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.
Objects remain in an unchanging, stable state of motion. Modifying a condition or factor (the strength of a push or a pull) might cause the object to start, stop, or change its motion.
