Follow the directions on the Vertical Motion page, to complete each of the sections below.
**__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.

 11) You are standing on a bridge over a creek holding a stone 20 feet above the water. You throw the stone upward with an initial velocity of 30 feet per second. How long will it take for the stone to reach the water?
 * The reason this is the right equation is because in the problem it provides us with the C part of our equation which is 20 then as we read it and it told us the Initial velocity which we need to find the speed or answer of our solution. So then we plug them both in into our equation which is H sub zero = -16t squared + 30t + 20 and that is why we think this is the right equation. **

**__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? The discriminant will be 30 - 4 (-16) (20). C is the y-intercept. If A is (-,+) the graph will either be up or down. If it was a whole number it will get smaller and if it is a fraction the graph will get bigger. Our graph will be facing down and small because A in negative. **__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 and explain what they mean for the problem you were given. This is the Quadratic Formula, the first one is the work we did to fine the Axis of Symmetry, and we concluded that the Axis of Symmetry is -0.9. This is the same Quadratic Formula and this is the work we did to find the Vertex and we concluded that 9 is he Vertex. **Where is the vertex? The graph and labels? The explanations?**
 * __The Solution and The Meaning__ :** What do the different parts of the graph mean? What does the solution mean?

Axis of symmetry is the line that is in the middle of the parabola where the vertex point is at. The vertex of any parabola is either the minimum or maximum depending if it opens up or down. **__Reflection__:** How did it feel to do the work and pretend to be the teacher? Do you think you understand the material more, now? Why or why not?

Madie: I really liked being the teacher. I understand that it was hard and that teachers can get stressed just as much as students can. Some of the material I do understand but others i might need more help later on. I thought doing the graphing was more difficult then the other stuff. I found that the quadratic formula was the easiest because that is what I am good at. I have also found that I do not want to be a teacher when I am older unless it was for little kids.

Taryn: I thought the hardest was finding the points to graph the equations. I did not remember how to do that. I understand how to work these problems better but it is still confusing. I thought it was cool being a teacher.

Tina: What I found difficult to do was solving the problem because I never really understood it. What I would do to run smoother was.... It helped me with quadratic equations but I have kind of a good idea about it. It felt good to do the work and pretend to be the teacher because it will just show that I understand.

Smilez: Getting the meaning of the problem and graphing I found the hardest not getting off task as much. It helped me learn about vertical motion when before I did not know much. It felt rewarding to finish and help my group.
