2. Objective Determine the interval of high and low tides Agenda Tide Notes Graphing the Tides Lab Comets

3. Tides Never give up, for that is just the place and time that the tide will turn. -- Harriet Beecher Stowe I do not know what I may appear to the world; but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me. -- Isaac Newton

4. Earth Moon Tides Tides are the vertical movement of water, specifically the alternate rise (flood) and fall (ebb) of water in the ocean. This is mostly noticeable along continental shorelines. The influence of the Moon’s gravitational force acting on the Earth’s oceans and the Earth (the rocky part). Why?

5. Earth Moon Sun High Tide High Tide Low Tide Low Tide Tides are more influenced by the gravitational effect of the Moon than they are by that of the Sun (the Moon's closeness to us outweighs by far the Sun's greater size). So, as the Earth spins around its axis, how many high and low tides do we have a day?

6. Earth Moon Moon Spring Tides The gravitational affects of the moon and sun combine to influence the flow of the oceans on Earth. New Moon Phase of the moon? Full Moon Phase of the moon? Moon New Moon Phase of the moon? Higher high tides and lower low tides

7. Earth Moon Moon First Quarter Phase of the moon? Third Quarter Phase of the moon? Neap Tides The gravitational affects of the moon and sun fight each other with their influence on the flow of the oceans on Earth. Moon Third Quarter Phase of the moon? Lowest high tides and highest low tides
