1. Due Now: Name the relationship The relationship between the amount you practice and your skill level The temperature change during a year The change in a person’s weight as they travel from the Earth to space.

2. Topic: Graphing the Changing Environment Seasons Day/Night Time

3. Graphs

5. Parts of a Graph -

6. X Axis – Independent Variable - Origin Y Axis – Dependent Variable -

7. Setting up a graph Relationship between hours worked and pay Independent Variable – Working Hours Dependent Variable – Pay

8. Graphing – Hours worked & Paycheck Time Worked (hours) Pay (dollars) 28 14 21 7 1234 When hours worked is low pay is low When hours worked is high, pay is high Direct Relationship

9. -

10. Inverse or Indirect Relationship X Axis Y Axis Temperature Density -  -

11. Cyclic (Cycle) Relationship Time (hours) Tides Low High -

12. Constant – No change-Static Travel from the Earth to the Moon Mass -

13. Non-Sense Graph DO NOT PICK – NOT POSSIBLE

14. Rate of Change - Rate of Change = Change in Field Value Change in Time

15. Graphing – Hours worked & Paycheck Time Worked (hours) Pay (dollars) 28 14 21 7 1234 What is the rate of change between these two points?

16. Example 21 Dollars 3 Hours 7 Dollars/Hours (28 – 7) Dollars (4-1) Hours

17. Example A B C D What is the rate of change from point A to point B Years (1986 = 1) Number of Cell Phone Users

18. (3000–1000) Users (4-2) Years Example (A-B) 2000 Users 2 Years 1000 Users/Year

19. Example A B C D What is the rate of change from point B to point C Years (1986 = 1) Number of Cell Phone Users

20. (14,000–3,000) Users (7-4) Years Example (B-C) 11,000 Users 3 Years 3,667 Users/Year

21. Example (C-D) What is the rate of change between Points C and D?

22. Extrapolation X Axis Y Axis Temperature Density -

23. Interpolation X Axis Y Axis Temperature Density -

24. Equilibrium - - Dynamic

25. Dynamic Equilibrium -

26. Example – Oceans are constantly evaporating, why is the ocean level remaining constant?
