Tides Resource


>> Why was this helpful?
      Even though I remembered a lot about tides from when I learned it in middle school, this video reminded me of things I had previously forgotten. It also had a lot of interesting fun facts that were interesting to know, even though I didnt need to know them. Plus the effects are cool. The earth will experience two high tides each day and two low tides per day. There will be approximately 6 hours between the different kinds of tides, 12 hours between tides of the same sort.


      The difference in force that is felt on opposite sides of the world can be explained by the difference in distance between the side of the planet and the moon. The side that is closer to the moon will experience a greater force. This difference in force causes the water to be pulled away from the surface of the earth, thus creating tidal bulges.

   
     Above you will see diagrams of  spring and neap tides. Spring tides will occur when we are experiencing a new moon or a full moon. Neap tides will occur when we experience a quarter moon.


     The chart above is a tide chart from Bald Head Island, NC. At the current time, they are experiencing a low tide. The are experiencing a neap tide, because it is a quarter moon.

Newton's 3rd Law Resource



>> Why was this video helpful?

This video puts Newton's third law in a situation that I can understand. Real world examples help me better understand how the law is applied outside of the examples given in class. Plus, I just thought it was cool that a video like this was even made.
