7. Types of Change
Cyclic Change: change that occurs in a regular, repeating pattern

8. Types of Change Non-cyclic Change:
change that occurs at random with no observed pattern

9. What is a rate?
How fast something occurs; a change in field value with respect to time

10. How can graphs help us determine the rate of change?

11. What is the rate that the flower grows?
Time (weeks)
Growth
(cm) 1 2 3 5 4 8

12. 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
