Presentation Transcript

  1. In 1950's mining town called Coalwood, Homer Hickam is a kid with only one future in sight, to work in the local coalmine like his father. However in October 1957, everything changes when the first artificial satellite, Sputnik goes into orbit. With that event, Homer becomes inspired to learn how to build rockets. With his friends and the local nerd, Homer sets to do just that by trial and a lot of error. “Sometimes one dream is enough to light up the whole sky. “

  2. Unfortunately, most of the town and especially Homer's father thinks that they are wasting their time. Only one teacher in the high school understands their efforts and lets them know that they could become contenders in the national science fair with college scholarships being the prize. Now the gang must learn to perfect their craft and overcome the many problems facing them as they shoot for the stars.

  4. BLAST OFF!: Rocket Quandary ProjectTwo friends, Regina and Brenda, are members of the NASA rocket club but go to different schools. Regina goes to South East High School and Brenda attends South Gate High School. Each of their schools is having a competition to see whose model rocket can stay in the air the longest. Mr. Eng helped the students construct equations that describe the height of the rocket from the ground when it has been launched upward from the roof of the school. The following are Regina’s and Brenda’s equations: Brenda: h=where t is measured in seconds and h is measured in feet. Regina: h= Where t is measured in seconds and h is measure in meters.

  5. QUESTIONS TO ANSWER (42 pts):1. (6 points): Discuss the Y-intercept for each quadratic equation (Use the key word: height).2. (15 points): Explain how to find the x-intercepts (roots) of the graph of a quadratic function by graphing, factoring, or using the quadratic formula. In general, what do the x-intercepts of a quadratic mean? How many x-intercepts can a quadratic function have?

  6. 3. (15 points): Analyze the path of each of the rockets: Use math and science vocabulary words such as axis of symmetry, vertex, opens up/down, maximum height, and gravity. 4. (6 points) Use your great algebra skills to determine whose rocket stays in the air the longest. Explain how you used the graph to answer the question.

  7. HELP HERE! • Graphing Calculator online ( click!) • In the top bar, type in your function (ex. : (x^2) + 2) • Press "next" and "previous" to see your lines. • Make sure these appear on the bottom as buttons: "grid on", "continuous", "trace ON" • With "trace ON", you can put your mouse over the parabola and it will give you the coordinates (ordered pair)
