Tide tables, commonly seen in newspapers and on television in coastal areas, show that comparable local high and low tides occur almost one hour later from one day to the next. The motion of the Moon as it revolves around the Earth largely accounts for the time lag. Students participating in this activity will investigate this time lag by using the tide time diagram and instructions which are provided. ... Full description.
