Tides website

This website posts data from water level stations at specific sites in the United States.   It would be a great way for students to read graphs in a more relevant manner as a possible webquest.   The students could visit different cities in different states to see what the high and low tides are like (Alaska’s are different than those in Oregon, which has the standard 2 high and 2 low tides).   Students could get practice drawing graphs and finding differences between them.
