How does the tidal range change during a month?
Students will compare the phases of the moon to the changes in the tidal range. Visit Phases of the Moon. Available: http://aa.usno.navy.mil/AA/data/docs/MoonPhase.html Why are the tidal ranges largest during a new and full moon and smallest during the quarter moons? Teacher will identify tides that occur under a full and new moon with the largest tidal range as Spring Tides. Tides that occur during the quarter moons with a small tidal range are Neap tides. Education Elements: STUDENT ACTIVITY This NASA site contains a student activity on timing the tides. http://topex-www.jpl.nasa.gov/education/activities/ts2siac3.
