GREER SCIENCE

CONCEPT 1

WHAT IS SPEED?

KNOW >

I know that speed is the distance covered by a moving object in a certain time.

APPLY >>

I can calculate the speed of an object by applying the equation:

speed = distance travelled ÷ time taken.

speed = distance travelled ÷ time taken.

EXTEND >>>

I can extend my knowledge of speed and explain the difference between average speed and instantaneous speed.

CONCEPT 2

DESCRIBING JOURNEYS WITH DISTANCE-TIME GRAPHS

KNOW >

I know how to interpret distance-time graphs and I can calculate the speed of an object using values from the distance-time graph.

APPLY >>

I can apply my knowledge of distance-time graphs to compare the speed of an object at different times of the journey and to also describe what acceleration is.

EXTEND >>>

I can extend my knowledge of distance-time graphs to explain complex journeys.

CONCEPT 3

RELATIVE MOTION

KNOW >

I know how to describe relative motion.

APPLY >>

I can apply my knowledge of relative motion to calculate the relative speed between two moving objects. uyuyuyg

EXTEND >>>

I can extend my knowledge of relative motion to predict how objects may appear to move when viewed from different points of view.
