1. Satellite Dish Project
An Algebra 2 Quadratic Project

2. Outline Introduction Phase I: Research Phase II: Make a Model
Phase III: Show Off Time

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 Brochures which included the following information
(as well as your 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?

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

21. Testing the Products

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

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

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

28. This is the outline where we glued the foam pieces down
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.
