  • 1. What are causes and effects of a hurricane?
    By Lydia and Jenna
  • 2. 2 quart plastic bowl
    Tap water
    Scissors
    String
    Stick
    Paper clip
    Masking tape
    Black pepper
    Wooden spoon
    Paper
    Materials
  • 3. 1. We filled the plastic bowl three fourths full with water.
    2. Next we cut the string one inch longer than the plastic bowl.
    3. After that we tied one end of the string to the paper clip.
    4. Then we tied the other end of the string to the stick.
    Steps of the experiment with pictures
    5. We sprinkled pepper over the surface of the water in the bowl.
  • 4. 6. We stirred the water with a spoon counterclockwise.
    7. While the water was swirling we quickly suspended the paper clip in the center of the swirling water.
  • 5. Results
    All the pepper collected in the middle that represented the eye of the hurricane.
    If you moved the stick to the side of the bowl and the paper clip is still suspended the water pulls the paper clip to the middle that tells us the wind of a hurricane is stronger on the outside.
    The paper clip didn’t move that much because it was in the middle, and in the middle of a hurricane the winds are much calmer then the outside of a hurricane.
  • 6. More Results
    We cut out two triangles from the piece of paper and stirred the water in the bowl. N ext we put the triangles in the bowl one on the side and one in the middle. We counted how many times the triangles went around the bowl in 10 seconds, that represented how fast the wind of a hurricane is. The wind is faster in the middle of a hurricane we know because when we did the triangles the average results in the middle were 15 times around and on the outside the average results were 3 times.
  • 7. Hurricane information
    This is how a hurricane works and how it is made.
  • 8. More Information
    Hurricanes usually travel at the speed of 10 to 30 miles per hour.
    The winds in a hurricane are 75 to 200 miles per hour.
    Usually the eye of a Hurricane has about a diameter of 20 miles.
    A hurricane can get up to 600 miles across.
    A hurricane can last over 7 days.
    Hurricanes are formed in late summer or early fall, over tropical oceans. The oceans have to be 80 degrees F
  • 9. Even more information!
    A hurricane can unleash more energy in a day than 500,000 atomic bombs.
    When a hurricane is over land or cool water it often shuts down.
    A hurricane can rip trees out of the ground, destroy homes, and cause GINORMAS floods.
    Some people in different parts of the world call hurricanes different names like cyclones and typhoons.
    .
  • 10. A hurricane rotates counterclockwise.
    Hurricanes can’t be formed near the equator.
    Outside the eye warm air spirals upward.
    A hurricane can make waves 20 feet high and it is called a storm surge.
  • 11. Make sure your doors are tightly shut.
    Bring flags and awnings inside.
    Don’t park cars under trees.
    Make sure your pool covers are secure.
    Hurricane Safety Tips
  • 12. What we learned about God during our study
    Genesis 7:17-18
    For forty days the flood kept coming on the earth, and as the waters increased they lifted the ark high above the earth.
    We decided to use this verse because God is like a hurricane and a flood. He is very powerful like these two destructive storms.
  • 13. God is amazing!
