Measuring the Rate of Change Mr. Cloud Earth Science
Graph A Graph B
Types of Change Cyclic Change: change that occurs in a regular, repeating pattern
Types of Change Non-cyclic Change: change that occurs at random with no observed pattern
What is a rate? How fast something occurs; a change in field value with respect to time
How can graphs help us determine the rate of change?
What is the rate that the flower grows? Time (weeks) Growth (cm) 1 2 3 5 4 8
What was the rate of growth from week 2 to week 3? Rate = change in field value time Rate = 5cm-2cm 1 week Rate = 3 cm/week
