  gravity   重力 - the earth gravity cause the ocean on the earth to following the moon.
  Waterlevel- 水的等级- when the water is high or low .

                         Summary
     The spring tides is our project title.Lunar revolution is when the moon moving around the earth and the length of it is 27.3 days.Phase of moon is the moon have different shadows. when the moon moving around the earth gravity cause the ocean on the earth to following. when the water is high or low it is called the water level. when the water doesnt changer it is called the sealevel.the sealevel always is zero. The cause of spring time is when the earth, moon and sun stay on the same line. The gravity cause the water higher than usual and lower than usual.
     The concution is the gravity effert the season on the earth, also can cause the spring tides.


             The critical thinking question
      
               how is earth affected by movement?
      The earth is affected by movement. The earth movement cause the day and night.The earth movement cause the season.The earth movement cause the different shadows of the moon.

              
                Reflection
        I enjoy most about this project is the video because when we make the video we try very hard.
        The most challening for me during this project is presentation because i dislike presentation.
        The new skill i learn from this project is teamwork.
        I think our video is no good. next time we will do better than this time.
