Transcript: Background Information What we found out: Yes the moon has a gravitational pull on ocean tides which causes them to be high or low and one can say the moon’s phases indirectly affects the beaches landscape through erosion and deposition. But the catch is this. We know that the moons phases and its gravitational pull cuases the tides to go back and forth in a steady like motion. This causes erosion and the ocean then sorts out the beach scape through deposition. Now to actually observe how that erosion and deposition would take geologic time. Time we dont have. Science Exit Project PowerPoint Table of Contents The first thing that we do every time we go to observe is find our landmark. In this case, we found a pipe and trash can looking thing Next, we right down the phase of the moon. If we can't see it, we look on the internet for the calendar to see what the phase is. Next we begin to take the pictures. We review our pictures from the previous observation, and see if anything has changed. We look to see how far the tides come out, by using the damp sand. We also infer how some of the deposition came about. For example, we took a picture of some seaweed that was close to the parking lot. We inferred that maybe Hurricane Sandy deposited seaweed there. Sometimes we sketch a picture of the ocean tides, (They don't always look that great). If the moon has a gravitational pull on ocean tides which causes them to be high or low then one can say the moon’s phases indirectly affects the beaches landscape through erosion and deposition. How We Came About It Problem The moon has mass, therefore it has gravity. As the moon orbits the earth, its gravitational pull not only keeps the moon from departing its orbit due to centripetal force, it also pulls the ocean water around with it. A spring tide is when the Moon, Earth, and Sun fall in a straight line. These spring tides occur twice each month, during the full and new Moon, and we notice the greatest difference between high and low tide water levels. If the Moon is at perigee, the closest it approaches Earth in its orbit, the tides are especially high and low. When the Sun and Moon form a right angle, as when we see a half moon, their pulls fight each other and we notice a smaller difference between high and low tides. These are called neap tides. Analysis During the earlier days when we went to just view the moon and sketch it we did this 1.Travel to Howard Beach 2.Observe the phase of the moon 3.Observe if the water has receded moved up or stayed put 4.Sketch if possible Nowadays after we started going more we do this 1.Travel to Howard Beach 2.Observe the phase of the moon 3.Take as many relevant picture of the landscape and of the tides 4.Observe if the water has receded moved up or stayed put [They obviously have since they are spring tides] 5.No sketches needed pictures only Semi-diurnal tides occur twice a day. This means a body of water with semi-diurnal tides, like the Atlantic Ocean, will have two high tides and two low tides in one day. Diurnal tides occur once a day. A body of water with diurnal tides, like the Gulf of Mexico, has only one high tide and one low tide in a 25-hour period. Some bodies of water, including parts of the Pacific Basin, have mixed tides, where a single low tide follows two high tides. Procedure We wanted to choose an exit project that was different from the others' in every way. That's why we chose to involve the moon in our project. This was a ludicrous idea at first. We obviously can't just observe the moon without a legitimate purpose. Earth's gravity is strong enough to hold down everything on the planet. That is, except for water. This is because water is always moving. This makes it attainable for the moon's gravitational pull. This causes four special tides, two high tides, and two low tides. This affects the beachscape, of Howard beach. Thus, our experiment was made. How do the moon's How do the different phases of the moon affect the Howard beach landscape? 1. How we came about it 2.

Independent Variables: In our Experiment our independent variable was the moon and its phases determine the beach tides through its gravitational pull which in turn affected the beaches land scape. 2. Dependent Variable: In the Experiment our dependent variable is the beach land scape because it was determined by the independent variable the moon. The reason we say that is because the moon being our independent variable affects the tides which affects the beachscape. 3. Constants: A constant that was never changing were the days in which we visited and took pictures, sketched, and also observed the phase of the moon. 4. Levels of the Independent Variable: For one we noticed that during the winter the tides were calm and it was back behind the pipe. But
