Free Fall

http://www.youtube.com/watch?v=C6-AxMc9mig

1. I chose this video because it is an easy way to understand free fall and is described in a clear concise way that I can understand.  Also he go through the free fall equations with you so you understand how to solve them.

2. This video makes it better than others because he goes slow and explains how to solve all free fall equations.  He adds in and explains what he is doing to solve free fall equations rather than just doing the problem without explaining.  He explains what every variable or letter means in the problem and what is needed to solve it.

3. If I were to make a video I would do it similar to this video.  This is because i would be able to show the viewer how to do the free fall problem and also explain how I am doing it at the same time.  This gives someone a verbal and visual description of what free fall is and how to solve free fall problems.

Spaghetti Tower

                                                               Group Evaluation:

3. 84 centimeters
4. What I like about our design is how we have a a strong base and our straight point of spaghetti sticks to get past 80 cm.  What I dislike about our design is how we needed support sticks to keep the tower straight and the triangular center.
5. The biggest challenge we faced was getting the straight point of sticks to stay straight and not lean over. We were able to overcome this problem by adding some tape to the sticks in which kept them sturdy and straight.
6. If we had a chance to redesign our tower, I would change our triangular base and center into a square one to help support the structure more.

Self Evaluation:

1. During this activity I did feel stressed because this was not an easy task.  Sometimes I was stressed on getting the structure to stay standing, other times I was stressed on finishing in time.  No, I never wanted to give up because I was very determined to finish this tower and get it above 80 cm.  With ever spaghetti stick i was closer and closer to finishing which made me want to complete this task rather than give up.
2. Our design is some what similar to others in the room by how it has a base that is a triangle and it also has other spaghetti sticks leading to a second.  It is different by how it has a straight point to the top of our tower.
3. If I could add one more material to the mix, I would add super glue to help glue marshmallows together and spaghetti sticks to marshmallows.
4. My contribution to the group was being the architect and building the tower.

Spaghetti sticks- 16 = 160$

Tape- 20cm.= 200$

Total $= 360$
