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

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

8. Sample Schematics

10. Building the Prototype

13. 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”

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

15. Making the Base

16. Extra Supports and Surface

17. Installing the Focus

18. Some Finished Products

22. Testing the Products

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

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

27. Constructing Our Satellite Measurements Measurements –Focus: 16 inches –Diameter: 28 inches –Circumference: 87.92 inches –Height of dish: 12 inches –Curve: x 2 =16y

28. 1. Hard cardboard foam 2. Poster board 3. Ruler 4. Folder 5. Hot glue gun 6. Pencil

29. 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.

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

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

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

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