Lab Report of Spring and Rubber Band

1) Procedures :
  -gather all materials that are needed (rubber band, spring, weights, clips, timers, medal rod, paper, pen, and calculator)
  - place a little amount of weight onto the spring and measure the distance of how far it went down.
  -time the amount of time it took for a certain amount of oscillations (we did 15)
  - place more weight each time you do a new one
  - just continue to keep adding weight until you have enough data
  -be sure to right all you data done (such as the weight you put on and how far it went down)
  -place a little amount of weigh onto the rubber band and do the same thing for it as you did with the spring.
  -calculate the weight in grams into newtons.
  -graph displacement vs. force and also period vs. force.
  -calculate slope.
  -find the spring constant of the rubber band and the spring.
  -now the lab is done :)

2 and 3) Table Format and Analysis of Data:

 Above is our graph of displacement vs. force.

 Aboce is our graph of period vs. force

This is our set up above.

 Above is our data that we wrote down. The weight we put down and the oscillations and time.

 Above its continued on the rubber band.

 Above again is our set up.

 Above is the rubber band with weight on it.

Above is the spring and rubber band in action with weight on them.

Above is our calculations of our Spring Constant. The bottom work shown is the rubber band's spring constant.
4) I learned that a spring bounces more slowly with more weight than a rubber band does. The more bouncy an object is the more it will bounce than an object that is more stiff. An error that happened with us was we timed our oscillations wrong the first time, so therefore our spring constant would be wrong and our graphs would be wrong too. An application that is applied to this lab would be a bungee jump cord. The more bouncy it is the more trips you will take up and down. Also, there will be more time. If the cord is stiff like a rubber band, then you won't have much time on the cord, and you wont bounce as much.

Cardboard Chair Project!

Here are the pictures of my group and I beginning to build our cardboard project.

*In the pictures below, we are gathering our cardboard we will be using, the glue, and the scissors we will also be using. We gathered the cardboard from Kendall's garage and the glue and scissors from her cabinets in her house.

*The pictures below are of my group and I beginning to cut the sides (legs) of the chair and the seat. We measured a distance of the seat and the length with a measuring tape. (sorry...one of them is sideways and I don't know how to change it) sorry :)

*The pictures below are of us beginning to place our chair together. We are placing the legs and the seat together to form the bottom of the chair.  We have a front view of the chair and we also have a side view of the chair.
