  • Introduction

  • Phase I: Research

  • Phase II: Make a Model

  • Phase III: Show Off Time

  • Phase IV: Why it Works


Introduction
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
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?



Phase ii make a model
Phase II: Make a Model

  • Students made schematic drawings and prototypes







Prototype formula
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”


Phase iii show off time
Phase III: Show Off Time

  • Students build full scale dishes and make power-points

  • Dishing out a better future


Function

4p

Vertex : (0, 0)

4p=12 , p=3

Focus: (0 , 3) , Directrix : y=-3


Constructing our satellite
Constructing Our Satellite

  • Measurements

    • Focus: 16 inches

    • Diameter: 28 inches

    • Circumference: 87.92 inches

    • Height of dish: 12 inches

    • Curve: x2=16y



This is how the base of how our

satellite looked like but it wasn’t all

finished at this moment.


Step 6 made all 16 angles be the same so the satellite would work better.

Cut the focus to stick on the model

6 inches


Phase iv why it works
Phase IV: Why it Works made all 16 angles be the same so the satellite would work better.

  • Students learn the calculus behind reflection


Vertical beam on a curve
Vertical Beam on a Curve made all 16 angles be the same so the satellite would work better.

  • The slope of the reflected line is the average of the slopes of the tangent and normal lines


Vertical beams on a parabola
Vertical Beams on a Parabola made all 16 angles be the same so the satellite would work better.

  • The parabola has the feature that vertical beams are reflected through a common point, the focus.
