Use the Internet and find out the ocean level for at least the past 50 years in one location.  Be sure that the data shows ocean level and not tidal level changes.  Record the data in a table and make a graph to show how the ocean level has changed over that time.

 

 

Scoring Guide:

1 point             Data found for 50 years in one location.

1 point             Line graph made.

1 point             Both axes are labeled.

1 point             Scale is consistent.

1 point            Graph can be easily read (neat, large enough, etc).

1 point             Correct units for graph.

1 point             The data should show less than 1/2 inch in change.
