Math Honors 2: Portfolio Task 2 (due at 7:30 a.m. May 31 - Block A
OR at 8:30 a.m. June 1 - Blocks C & D)
TIDE MODELLING

Description
The Bay of Fundy in Nova Scotia, Canada is deemed to have the greatest average change in tide height in the world. In the table below data is presented from December 27 2003 using Atlantic Standard Time (AST). The heights were taken at Grindstone Island.

In this task you will develop a model function for the relationship between the time of day and the height of the tide. Consider carefully the expectations of a modeling task as you complete your work by referring to the assessment rubric. Method

1. Using a GDC or graphing software, plot the graph of time against height. Describe the result. 2. Use your knowledge of functions to develop two functions that model the behavior noted in the graph. Describe any variables, parameters, and/or constraints for the model. You should: (a) develop a polynomial function, by solving a system of equations using matrices (b) develop a trigonometric function, by analyzing key characteristics of the graph (c) discuss why exponential and logarithmic functions are inappropriate choices to model the height of the tide 3. Draw a graph of each function on the same set of axes as the graph in Step 1. How well does each function fit the data? 4. Modify each of your functions to create a better fit. Describe the issues you had to consider. 5. Good sailors will launch their boats on an outgoing tide (that is when the tide is going out). Use each of your modified functions to determine the times between which a good sailor would have launched a boat on December 27 2003. 6. Use the regression feature of your GDC or software to develop best-fit polynomial and trigonometric functions for this data. Compare these functions with the ones you developed analytically. 7. The table below lists the tide heights for December 28 2003. Does your...

...really should be worried about is drowning in the oceans strong currents with nothing to grab or hold on to and nothing around them but water. Many underestimate the strength and the aggressiveness of the rip tides that have the ability to pull them out to sea and eventually take their life. Rip tides are the most hazardous natural disaster for people that go to the beach on a regularly basis. It is also recorded by the National Oceanic and Atmospheric...

...1.0 What Causes the TidesTides are periodic rises and falls of large bodies of water. Tides are caused by the gravitational interaction between the earth and the moon. Tides are the cyclic rising and falling of earth's ocean surface caused by the tidal forces of the moon and the sun acting on the earth . Tides cause changes in the depth of the sea and produce oscillating currents known as tidal streams, making...

...Earth and 24kg on the moon. This explains weightlessness in space. In space there is no gravity, so you have no weight.
Tides
At any time on earth there are 2 high tides and 2 low tides, each directly across from each other, as shown in the diagram above. In this diagram,(from Physics for a modern world 1986), points 1 and 2 are at high tide and points 3 and 4 are at low tide. The force of the moon on the earth complies...

...Tides:
Caused by gravity from the sun and the moon pulling on and deforming large bodies of water.
Daily changes in tides:
High tides occur on the side of earth closest to the moon and the side opposite the moon.
- High tides draw water away from the areas between, causing low tides to form.
For most places on earth, high tides occur every 12 hours (twice a day).
High and low are about 6 hours...

Wave Characteristics Wavelength = the distance between the crest of two adjacent waves. Wave Amplitude = the distance between sea level and the crest. Wave Crest =the highest point of the wave. Wave Trough = the lowest point of the...

...hours for tourist travelling to watch their Bore Tide. A Bore Tide is a tidal phenomenon in which the leading edge of the incoming tide forms a wave (or waves) of water that travels up a river or narrow bay against the direction of the river or bay's current. Anchorage, Alaska is known for its famous Bore Tides. These bore tides occur at least once a day during high and low tide. Yet, health warnings are...
