Observations use one or more of the senses.A measurement is an observation.
An observation cannot be an inference.An inference is based on observations.
Predictions are inferences about the future.

How does the density of the Earth change as you go from the surface to the center?
How does the density of the Earth change as you go from the surface to the center?
Density increases from surface to center.
From 100o C 4o C water becomes _____in size and therefore ____ dense. From 4o C 0o C it becomes _____ in size and therefore ____ dense.
From 100o C 4o C water becomes smallerin size and therefore more dense. From 4o C 0o C it becomes larger in size and therefore less dense.

Do the graphs below show interpolation or extrapolation?Interpolation
A faster rate of change is indicated on a line graph where the slope of the line is ________.
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.
