Process
Your group will be assigned a vertical motion problem, and your job is to present your solutions in the form of a wiki. Follow the steps and guidelines below, paying close attention to the directions. Group Roles.

To complete this project, your group will need to use several different computer programs. Click on the links below for tutorials on how to use each program:
Notebook
MathType
Geometer's Sketchpad
Take a screenshot

The Word Problem: How would you solve for time in the problem your group was assigned? Prepare the equation to solve for time, defining the variables and supporting your choice in equation.

  1. Write the word problem assigned to your group in your wiki. Include at least one picture that is relevant to your group's problem.
  2. Choose the appropriate vertical motion equation and write it down in your wiki (using MathType). Why is this the correct equation to use?
  3. Define each variable and describe how each one relates to your vertical motion problem.
  4. Write the equation in standard form.

The Parabola: Use what you know about parabolas to predict the shape of the graph. What will it look like, and how do you know?

  1. Identify a, b, c.
  2. Predict the effect of a. What will the sign of a (+ or -) do to the graph? What will the magnitude of a (whole number or fraction) do to the graph?
  3. Predict the effect of c on the graph.
  4. Calculate the discriminant. What does that number tell you about the graph? Show your work using MathType.

The Math: Pretend you are the teacher, and this section is your lesson. Post the calculations required to graph the equation and find the solution, and show all the steps to doing so. Teach your audience all the important parts of the graph.

  1. Calculate the axis of symmetry and vertex. Show your work using MathType.
  2. Graph the function using Geometer's Sketchpad . Copy and paste it into Notebook .
  3. Label (using Notebook software):
    1. Roots
    2. Axis of Symmetry
    3. Vertex
    4. The y-intercept
  4. Take a screenshot of your labeled graph and post it on your wiki page.
  5. Determine the best way to solve for x and do so. Which method did you use and why? How do your answers compare with the roots on the graph? Use MathType to show your work.

The Solution and The Meaning: What do the different parts of the graph mean? What does the solution mean?

  1. Describe what your solution means to your vertical motion problem.
  2. What does the vertex represent? Why?
  3. What does the y-intercept represent? Why?
  4. What do the roots represent? Why?
  5. How long is the object in the air? How do you know?

The Reflection:

Each member of your group needs to complete the reflection on their own. Post each person's reflection at the bottom of your wiki. Be sure to label each reflection with the name of the person who wrote it.
  1. What was one thing you found difficult to do, and why?
  2. What would you do differently next time to make the project run smoother?
  3. Did doing this project help you understand quadratic equations and vertical motion any better? Why or why not?
  4. How did it feel to do the work and pretend to be the teacher?

Notes

DUE DATES
6/28/10: I graded everyone's projects (parts 1&2 only) and left comments. Both parts counts as a homework assignment (5 points each). Overall I was very pleased. If your group hasn't finished both parts yet, let me know when you do and I'll regrade them. If you have any questions, please let me know. :) ~Mr J

7/7/10: All wikis have been grade through part 3. Most are very good, a few are behind a bit. Remember that the final project is due this Friday. If you're group needs more time, come in during lunch or after school. You can also work on the typing parts at home. Keep it up, we're almost done! :) ~Mr J
