 * __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)  You are standing on a bridge over a creek holding a stone 20 feet above the water. You release the stone. How long will it take for the stone to reach the water? [[image:bridge.png width="298" height="171"]]
 * 2) This equation is the proper one to use because the stone is dropped not thrown, so there is no velocity.[[image:Vertical_motion_equation.png width="251" height="68"]]
 * 3) //h// is the desired point, //t// is the time it takes to get to the desired point,and //h//naught is the starting point.
 * 4) [[image:65standard_form.png width="228" height="54"]]


 * __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) [[image:65abc.png width="165" height="177"]]
 * 2) //a// tells if the parabola opens down, to be a maximum, or up, to be a minimum.//a// is negative so the parabola will face down and is a maximum.//a// is negative sixteen therefore the parabola will open down and be very slim.
 * 3) c is the vertex.
 * 4) [[image:65discriminant.png]]the discriminant is positive so it has real roots.


 * __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.


 * 1) Axis of Symmetry
 * 2) [[image:axis_of_sym.png width="104" height="92"]] The axis of symmetry is the line that divides the parabola in half. This will help us create the parabola by making it easier to find the vertex. In this case, we know that the vertex is on the y-axis.[[image:65graph.png width="536" height="428"]]
 * 3) [[image:65equation.png width="200" height="200"]]


 * __The Solution and The Meaning__:** What do the different parts of the graph mean? What does the solution mean?
 * 1) Its the vertex, its where the problem begins.
 * 2) The vertex represents the maximum, or highest point of the rock.
 * 3) The point on the graph in which the point is at its highest (also where the rock is dropped).
 * 4) The water level. The point on the graph that touches zero (the point where the point where the rock is released).
 * 5) The rock is in the air 1.5 second because the X-axis shows time and the rock lands at 1.5 on the X-axis.


 * __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

__Chris__-I don't think i ever tried graphing a vertical motion equation before so it was difficult for me a little bit.I would need to study more and the graphing would be probably be much more simpler for me.I understood a little more when i saw my partner do the graph, it really helped me a lot.Being a teacher on this wiki felt like if i had respect.

__Nebai-__ I personally thought that the part three was the hardest and we had to work on that for the most amount of time because of the absences in the group members. To make the project better next time, I would work with my group members and work harder. I don't understand the material any more now because I was absent for most of the project. I wish I was here because I don't get the vertical motion stuff. To be the teacher is frustrating because you have to be specific and very clear.

__Alexis__-Solving the problem was the most difficult of all.To make this smoother,i would make someone pay more attention.This project allowed me to understand much better.It was nice to be a teacher, but i wouldn't want to do this again because i feel nervous because the whole world might read it.
