Team Activities
Creating Waves (Required)
In this activity, you and your group will explore how wind speed and water depth affects the waves created during a hurricane. You will use the following materials to simulate your own hurricane.
Materials:
· Creating Waves worksheet
· Pencil
· 9” x 13” baking dish
· Flexible straw
· Tape
· Ruler
· Water
Set-up before starting the procedure:
1. Place the baking dish on a desktop.
2. Bend the straw so that it forms an L shape.
3. Place the straw inside the baking dish in the middle of one of the 9-inch sides, so that the shorter end faces straight up, touching the side of the dish, and the longer end is suspended about half an inch over the bottom of the dish. One open end of the straw will stick straight up, and the other will face the opposite 9-inch side of the dish.
4. Tape the straw to the inside of the dish to hold it in place.
5. Pour water into the dish until it reaches just below the straw.
Procedure:
1. One group member should blow very gently into the end of the straw that is sticking straight up, creating “wind” over the water in the dish.
2. Another student should observe the water at the opposite end of the straw and mark the wave height on the outside of the dish.
3. Measure and record the wave heights, beginning their measurements from the desktop.
4. Repeat the procedure two more times, blowing harder each time, and record measurements to assess the effect of wind speed on the height of waves.
5. Remove the water from the dish, move the straw up near the top of the dish, and refill the dish with water until it reaches just under the straw.
6. Repeat the procedure to compare wave height in deeper and shallower water.
7. Each student will fill out the Creating Waves worksheet including reporting the results and conclusions.
8. Clean up materials.
9. Turn in worksheet to your teacher.
