Satellite Dish Project An Algebra 2 Quadratic Project

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

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.

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?
