Ocean Tides Activity

Grade Level: Middle School and High School Level

Overview: This activity is designed to show students the relationship between ocean tides and the
lunar movements. It uses the tide charts for Boston Harbor to show these relationships. It
has been used with both middle school and high school students with success.

Time Frame: The activity can be completed in two class periods, with time allowed out of class for each
student to complete his/her tide chart plotting.

1. Students will learn the effect the moon has on tidal ranges.
2. Students will plot high and low tides for an area as well as the lunar phases using actual
tidal data for a one-week period.
3. Students will learn that extremely high and low tides are related to very specific times of
the month..
