Part 2: Use the graph paper provided to graph the level of the high tides (shaded

column only) in feet for a month. Plot the days of the month on the x-axis), and the

tide level along the y-axis. After you have graphed the tide data answer the questions

below.

1. What kind of patterns does the data reveal? ____________________

2. Tides are cyclic and closely follow the phases of the moon. During the new and full

moons, the distance between the high and low tides increases, which means that

high tides get higher and low tides get lower.

a. From your graph, pick the date that has the highest high tide.

b. What phase of the moon is associated with this high tide?

c. From your graph, pick the date at the second highest peak of high tide.

d. What phase of the moon is associated with this high tide?

e. From your graph, pick the date that has the lowest high tide.

_________

f. What phase of the moon is associated with this high tide?

____

g. From your graph, pick the date that has the second-lowest trough on the curve

for the lowest high tide.

h. What phase of the moon is associated with this high tide?

3. The alignment of the Sun, Moon and Earth affects how high the tides will be. Sketch

the alignment of the Sun, Moon and Earth at new moon.

What is the name for the tides that occur during this alignment?
