There is a Ferris Wheel whose center is 65 feet off the ground. The Ferris Wheel has a radius of 50 feet. The Ferris Wheel is moving at a rate of 1 revolution per 40 seconds. The diver is on the Ferris Wheel which always moves in a clockwise direction and will start from the 3 o'clock position. Here are some questions we explored.

1. When will the Diver be at the highest position? What is that height?

2. What is the angular speed of the diver? What is the linear speed of the diver?

3. Map the divers height for 1 revolution of the Ferris Wheel.

4. What height will the Diver be after 14 seconds?

5. If there was a 30 fence hiding the front of the Ferris Wheel, what percent of the time is the Diver ABOVE the fence?

6. How long does it take to go from the 3 o'clock position to the 8 o'clock position?

So with our Ferris Wheels IN OUR HANDS, we went through many of these questions while moving the wheel to match our questions. The students made the Ferris Wheel with their own hands. It was a homework assignment. I gave them 8 pipe cleaners and 2 Popsicle sticks and they had to make a working Ferris Wheel. They also had to make a place where the diver was on the Ferris Wheel. Kind of like a marker.

Here is one of my students talking about her experience with the Ferris Wheel.

I know I learn better when I can touch it, feel it, manipulate it and visualize it.

Best,
