1. Satellite Dish Project • Power-Point by Jordan Schettler

2. Outline • Introduction • Phase I: Research • Phase II: Make a Model • Phase III: Show Off Time • Phase IV: Why it Works

3. Introduction • The Superdish Network wants you and your research team to design and build a prototype parabolic dish. • Your team will be in competition against other teams for the job. • Everyone must contribute to make this a success.

4. Phase I: Research • Students made brochures which included the following information (as well as there own personal touch): • What is a parabola? • The standard form: 4p(y - k) = (x - h)2 • Vertex: (h, k), Focus: (h, k + p), Directrix: y = k - p • How does a satellite dish work? • What materials will you need for your project?

5. Student Sample

6. Phase II: Make a Model • Students made schematic drawings and prototypes

7. Sample Schematics

8. Sample Schematics

9. Building the Prototype

10. Building the Prototype

11. Building the Prototype

12. Prototype Formula • (x-h)2 = 4P(y-k) • 4P=16; P=4 • (0,0)= Vertex • Create formula • Draw • Build • Test EchoStar “We Work Together to Help YOU”

13. Phase III: Show Off Time • Students build full scale dishes and make power-points

14. Making the Base

15. Extra Supports and Surface

16. Installing the Focus

17. Some Finished Products

18. Testing the Products

19. Student Power Point Samples KTKM Corp • Dishing out a better future

20. Function 4p Vertex : (0, 0) 4p=12 , p=3 Focus: (0 , 3) , Directrix : y=-3

21. Constructing Our Satellite • Measurements • Focus: 16 inches • Diameter: 28 inches • Circumference: 87.92 inches • Height of dish: 12 inches • Curve: x2=16y

22. Hard cardboard foam • Poster board • Ruler • Folder • Hot glue gun • Pencil

23. This is the outline where we glued the foam pieces down. We made all 16 angles be the same so the satellite would work better. This is how the base of how our satellite looked like but it wasn’t all finished at this moment.

24. Step 6 Cut the focus to stick on the model 6 inches

25. Phase IV: Why it Works • Students learn the calculus behind reflection

26. Vertical Beam on a Curve • The slope of the reflected line is the average of the slopes of the tangent and normal lines

27. Vertical Beams on a Parabola • The parabola has the feature that vertical beams are reflected through a common point, the focus.
