> Using the positions of the moon relative to a location on earth, explain why the tides alternate from low to high during a 24 hour period and why there are usually 2 high tides alternating with low tides each day. 2.) The gravity from the earth to the moon pushes the tide closer and farther from the shore.
 * 1) View the top diagram above. Compare the relative positions of the earth, moon and sun to explain the differences between new moon, half moon and full moon phases. 1.) if the sun is stright up you will see the whole moon, and if the sun is off to your left you will only see a portion. Your location will determine the way you see the moon.
 * 2) View the example of the tide chart for the Gandy Bridge for a day. Tide Chart for Gandy Bridge
 * 1) Use the data from Gandy Bridge TidesTampa Bay Tides to **create a spreadsheet in Open Office** with the coefficient of the tides for the days in the month of October, 2015. Then **create a line graph of the data**. Indicate that the first row and first columns are labels. Be sure to label the X and Y axis, and to provide a title. Be sure to include units. //(Note:// On the Tide Tables there are tidal coefficients which tell us the amplitude of the tide forecast //(difference in height between the consecutive high tides and low tides in any given area). The highest possible tidal coefficient is 118, corresponding to the greatest high or low tide there can be, excluding meteorological effects. Tidal coefficients are calculated from the following parameters or from the sun and the moon: straight ascension, declination, parallax and the distance between the Earth and the celestial body.)//
 * 2) //Save the Tide Height spreadsheet as 8 last name initial tide. Save it as an html document. Saving it as an html will convert the chart to a jpeg. **Copy the spreadsheet data and paste it on your TideMoon page. Then Upload the jpeg of the chart to your page.**//
 * 3) View the Moon Phases October 2015 on the same Gandy Bridge Tides  . Find the moon phases for the high coefficients and low coefficients on the graph. Provide an explanation for the pattern of high coefficient of tides alternating with the low coefficient of tides during the month based on the relative position of the earth, moon and sun. 3.) Because the earth makes the seasons and in the seasons the sun and moon rotate and when they rotate, it changes the course of stuff that happenes on earth.
