1.  This is an introductory activity to the phases of the moon and the affect of the moon on tides.  For the younger grades: it would be helpful for students to have some prior knowledge on the phases of the moon. 

2.  Most students will require assistance with drawing the phases of the moon.  After going to moon definitions, show students that they can view the different phases of the moon by advancing the animation to the numerical quantity required to see the phase they want.  I indicated on the Student Page that the "Full Moon" and "New Moon" phases were labeled and drawn for them.  They are labeled, however, I lacked the expertise to draw them!  Sorry!!!

3. Allow students some time to explore the moon phases interactive.

4.  Students should choose a region to study from tidal region.

5.  Students will need to change some of the prediction options: number of lines (30), length of time (4 weeks) and then 
click "Make New Prediction."  After observing the table, students will change another prediction option: display type (graphic plot), pixels (640 by 320).

6.  Students should notice a horizontal "hour glass" shape to the graph.  Have them print it out if necessary and highlight the shape of the "hourglass."  The rounded portions of the "hourglass" indicate the highest and lowest tides of the month.  The 
part in between are the days in the month when the difference between high and low tide is minimal.  Occasionally, because 
of the region chosen and the moon phases, students will not see an hour glass shape.  Rather, students will observe a graph that has one rounded portion in the middle that tapers on either side of it.  The interpretation is the same. 

7.  Guide students to the realization that during the "rounded part of the hourglass" the highest and lowest tides occur.  What is the name for these types of tides?  During the flattened out time of the month there is very little difference between high and low tides.  What is the name for these types of tides? 

8.  Finally, guide students to realize what moon phases can be associated with those types of tides.

Data collection & interpretation, Predicting, & Graphing
Computer literacy
Effective use of Internet resources

Work sheet & graph (Sample Student Activity Sheet available at moon sheet)

1.  Students can select another region of the world.  They should compare the new ocean tides with their original data to determine differences in tides and moon position. 

2.  Students can graph data points by hand in order to predict the exact days of the 
Spring and Neap tides. Then they can further predict the precise days of the Full, 
New, and Quarter phases of the moon. 
By using moon phases interactive or another site students can verify their predictions.

3.  Students can also visit and read 
some poetry about the moon and its phases.  Students may wish to write their own poetry 
or short story about the moon.
