Students will develop a graphical model of the Earth-Sun-Moon system to describe the cyclic patterns of lunar phases and how they affect our tides.
In this activity, students will go to the NOAA website and collect tidal data from a region around the US. Students plot a month of tidal data and predict the moon phases based on how high the high tides are and how low the low tides are (spring vs neap tides). Students are amazed to find that their predictions are right by looking at the actual moon phases during that month!
This activity includes a rubric, student examples, an extension and clear instructions for students and teachers.
