Part B:

Initial Design: it is going to be a plastic jar with a lot of cotton balls in it .Then we are going to put                            the egg inside of a sock and put more cotton balls in it and then tape everything and put                          the teddy bear body parts on it so it will  make it look creative.

Materials list:
                         Cotton balls
                         Plastic mayonnaise jar
                         Teddy bear stuffing
                         Tape
                         Body parts of the teddy bear
                         1 CAP approved long sock
                         2 small balloons

Hypothesis: By combining the plastic jar and a lot of cotton balls in it when we throw the egg it is                       not going to break because the ground its going to hit the plastic and the plastic its going to                     hit the cotton balls so the cotton balls its going to touch the egg and it wont break it because                   the cotton balls are soft.

                  I stuffed a long sock with stuffing from a teddy bear. I then placed the egg into the sock and                   added more stuffing. I then tied both ends of the sock with balloons to keep the egg/stuffing                   tight. Next, I cut the plastic jar in half.  I  then cushioned the bottom with stuffing and put                       the egg/sock in. I put more stuffing on top. Then I put tape on top to keep everything inside.                   Finally I added extra cushioning to the outside with teddy bear body parts and stuck them                       with tape.

Part C:
                  Data: mass without the egg
                    71.76 g.
                   score calculation
                     2000.10
                       71.76
                  grade and number of points
                     278.70 points
                      A+

  Part D:
             Results:
                          Test number 1:HEIGHT :5 feet;  It did not break.
                          Test number 2:HEIGHT:7 feet; It did not break.
                          Final test: It did not break.

Part E:
               1. Explain your final design in 2-3 sentences  include materials.  
                    initial design was good so we did not change it because the egg did not brake.
                  All the materials that I used work really well.
               2. How was the design modified from your initial hypothesis to improve your results ?
                    I did not change it.
               3. What was the purpose of having multiple test drops of your structure ?
                     Because like a roller coaster the the higher you go, the stronger it feels on your body.                              Therefore we were testing the strength of the egg.
               4. Explain why your structure did or did not make the egg break.
                    My egg did not break because I put a lot of stuffing in it and the extra stuff that I put on the                     plastic jar helped because the ground did not hit the plastic jar, it hit the teddy bear body                         parts .
              5.If you could change your design in any way, what would you have done differently?
                    The only thing that I would change is that the color of the sock would be white and I                               would  paint the egg so if it would break, I don't have to open the whole thing to see if the                     egg broke.
