1. Challenge Project Water Wheel You are going to build a water wheel Use supplies found around your home

2. Helpful equations Area of a circle = A = π × r 2 Circumference of a circle = 2π × r R Volume of a cylinder = (2π × r) x H H Area of a rectangle = L x W Volume of a rectangle = L x W x H H W Area of a triangle = B x H L 2 H Volume of a triangular prism B x H x L 2 B L D

3. The Scientific Method

4. Task 1 Research Water Wheels Ideas: Look for a You Tube video showing how water wheels work. Make a sketch model of a water wheel and how it works. Include all calculations for proposed figures. Justify your decisions for sizes. Why is your wheel this size….etc. Be sure to include labels of the different parts of a water wheel and relative sizes of the parts compared to one another. Submit plan along with daily journal notes in you math journal to show progress to Mr. Hunter.

5. Geometry of water wheels Some questions to consider in you Journal. As you begin to build a water wheel what is the relationship between the size of the wheel and the energy it provides? Can you attach a fan to your water wheel and have it power the fan? In your journal you need to provide the dimensions of the parts of the water wheel

6. One idea for a sketch Tub filled with water The volume of the tub is? Pump Fan Shaft Water line For each figure calculate the area, and volume in your project. In you Math Journal justify why you chose the sizes you did. For example did A larger or smaller Wheel work better and why?

7. Example of a Journal Entry Student’s Journal Date: Draw a sketch of what you are planning to do today. Write a two to three sentence plan on what you are going to do today. Write a one sentence goal for the day.

8. Journal Entry Continued With the last ten minutes of class respond to the following. Did you accomplish your goal? Why or why not? What did you change in your plan. Why did you change your plan? (This is part of the scientific method). What do you know today that you didn’t know yesterday? What will be your goal for tomorrow?

9. Presentation You will present your water wheel and your finding to the class. Discuss how your thinking and understanding evolved throughout the lesson. How did math help you to improve your design?
