32. Water is most dense at 4 o C. ICE 0 o C 1 o C 2 o C 3 o C 4 o C Winter Lake – FILL IN THE TEMPERATURES FROM BOTTOM TO TOP.

33. DRAW A SIMPLE EXAMPLE GRAPH ______ relationship: This means as one variable ________ the other ________. Direct increases

34. Example Graph(s) ______ relationship: This means as one variable ________ the other ________. Direct increases

35. _______, or ______ relationship: This means as one variable ________ the other ________.

36. _______, or ______ relationship: This means as one variable ________ the other ________. Indirectinverse increasesdecreases

40. Type of Relationship Example Graph(s) _____ relationship: In this type of relationship something is ________ in a ______. This is very useful because you can ______ when another similar event will occur. Cyclic repeating pattern predict Equal time

41. Do the graphs below show interpolation or extrapolation?

42. Interpolation

43. A faster rate of change is indicated on a line graph where the slope of the line is ________.

44. A faster rate of change is indicated on a line graph where the slope of the line is steeper. Segment A Segment B Segment C Segment A of the graph has the steepest slope, therefore this is when the rate of temperature change is the greatest. Segment C has the lowest slope, therefore here temperature is changing the slowest. Notice that while the temperature is always increasing with greater depth, the rate of change is not steady. This means that the rate of change is not the same everywhere on the line. We know this because we can see that the slope of the line is not the same everywhere.
