Mr. Olson
Motion & Energy
4th grade students in Washington State are responsible to know:
Standard: The relative speed of two objects can be determined in two ways: (1) If two objects travel for the same amount of time, the object that has traveled the greatest distance is the fastest. (2) If two objects travel the same distance, the object that takes the least time to travel the distance is the fastest.
Performance Expectation: Measure the distance that an object travels in a given interval of time and compare it with the distance that another object moved in the same interval of time to determine which is fastest.
Measure the time it takes two objects to travel the same distance and determine which is fastest.
