    Initial Design:
    Materials used for the experiment:
    One small  plastic container,
    16 ounce plastic cup (to hold the cereal),
    small portion of cereal (rice crespies)
    One drainer cup
    One Egg

Hypothesis:

If I put a sufficient amount of cereal inside a container (cereal is the independent variable) then the egg will be protected from being cracked when thrown to the air onto the floor (the egg is the dependent variable).

Procedure for Construction:

First and foremost, with the drainer cup, you place the top inside the container and begin to throw cereal inside the container half way.

Second, when the container is filled half way you place inside the egg straight in the middle.

Next, you begin to add more cereal inside the container to cover the egg and protect the egg from the bottom to the top and side to side.

Lastly, you close the container tightly, and make sure you have sufficient amount of cereal for the egg protection.

     Data:
   

Mass of structure With Egg	Mass of Structure Without Egg	Score Calculation With the mass	# of points/ grade obtained
151 (B)	183.8 (B)	108 * 77g 2000/105.77= 18.38 * 10= 183.8	200/ 151= 13.2 * 10= 132.4 (B)

 

D.)

     Results:

     Test #1: The egg was thrown 2 feet high and did not brake. The egg was protected by the rice crespies cereal and sealed in cap, the fall to the floor prevented no damage to the egg.

    

 

 

Test #2:  The egg was thrown 4 feet high and still did not break. The plastic container had a sufficient amount of cereal the egg was fully protected from any damage.

     

 

 

 

 

     Final Test: Finally the egg was thrown to the air  and did not break. With the amount of cereal inside the container and the sealed protection the egg was very protected from cracking.

E.)
    Post Lab Questions:

    1.) Explain your final design in 2- 3 sentences, include materials:  My final design includes five materials; a plastic container, a 16 ounce cup, with rice crespies cereal in it, a cup drainer, and a egg. In order to protect the egg from cracking, rice crespies will be poured half way inside the container. Lastly, adding the egg inside the container in the middle, then adding more cereal to cover the egg. Finally sealed and protected, the egg will not break no matter how high it is thrown.

   2.) How was the design modified from your initial hypothesis to improve your result? The design was modified from my initial hypothesis to improve my result in one aspect. I had to take out a small portion of rice crespies, to test whether my structure and hypothesis does work. And to improve the weight of the structure, from heavy to light.

  3.) What was the purpose of having multiple test drops of your structure? The purpose of having multiple test drop is to prove whether my hypothesis works or not. The higher the container is thrown to the air one can test the different heights and see if the hypothesis is correct. Or if it needs to be modified to improve the result.

   4.) Explain why your structure did or did not break? My structure did not break, on all three test because the egg was fully protected. Protected in the sense the cereal that was added inside the container from top to bottom and side to side, held steady the egg; so that there will be no movement. The container being thrown at different heights wouldn't make a difference to the egg being crack because of the full protection the egg had.

  5.) If you could change your design in any way, what would you have done differently: If I had the chance to change my design in any way, I would think of a structure with lighter mass. The structure I came up with was too heavy; so I had to modified my structure, taking out cereal from the container to decrease the amount of weight it had. This will be the only change that I would have done differently in my experiment, to avoid from getting a low grade due to the heavy weight my original structure had.
