IntroductionIntroduction
• 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.

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?

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.
