Post Lab Questions

#1.) Explain your final design.

             My final design consisted of three car wash sponges, one dish sponge that was cut up, and rubber bands.The three car wash sponges were stacked on top of each other and two of them had a hole made into them to support the egg and I also put strips of the cut up dish sponge on the tip of the egg and secured it with a rubber band. To top it all off I put rubber bands on top of the three stacked up rubber band to hold them together.

#2.) How was the design modified from your initial hypothesis to improve your results?                                           The design was modified from my initial hypothesis to improve my results by removing the cotton balls to make the structures mass lighter so, that the ending grade would be higher.

#3.) What was the purpose of having multiple test drops of your structure?                                                     The purpose of having multiple test drops of my structure was to test how my structure would react to different sized drops.

#4.) Explain why your structure did or did not make the egg break.                                                                My structure did not allow the egg to break because it was supported securely by the sponges which allowed the egg to have cushion when it fell to the ground .

#5.) If you could change your design in anyway, what would you have done differently?                                 If I could change my design in any way I would chose a structure with less mass and I would have also been more creative and created something better looking to match it's amazing results.

                              

Results

• Test#1: During my first testing of my structure my partner and I dropped it off of a table and it did not crack one bit and it most certainly did not break.                                                                                             
• Test#2: During my second testing of my structure my partner and I dropped the structure from an approximately 12 feet drop and it once again did not crack or break.                                                           
• Final test: During my final testing of my structure Ms. Janik threw the structure in the air and it dropped back to the ground at an approximately 20 feet drop and just as I had supposed it did not crack or break.

Data

•  The mass of my structure without an egg: 89.32 g
• Calculation: 2000/ 89.32 * 10 = 223.9
• Number of points and grade: 89.32 g (mass) and 10 egg points with a grade of an A.
• The mass of my structure with an egg: 80 g

Egg Drop Experiment

My name is Alanie Quiles and this is my first structure of the egg drop experiment. My lab partner and I created this structure by using three car wash sponges, dish sponges, cotton balls, and rubber bands. Most importantly, we made a hole that will support the egg in the middle and top sponge as you can see in the picture above. Next, we cut up a dish sponge and used strips of it to cover the tip of the egg and also stuffed some cotton balls for some extra protection to the tip of the egg and used a rubber band to secure it all in place. Then, we put the top sponge that also had a hole cut into it on top of it all. Finally, we stacked all three sponges on top of each other and secured the entire structure with two more rubber bands. I tested the structure on a table and just as I supposed the egg did not break inside of the structure.
