Egg Drop Project Mission To construct a structure

Egg Drop Project

Mission To construct a structure capable of protecting an egg dropped from a significant height

Research: Car Crashes

Research: Parachutes Group 2

Research: Mars Rover

Design Considerations § § § § Layout of the structure Making the structure firm Cushioning the egg Slowing down the structure Length of the fall Materials Cushioning the fall of the structure

Materials that we used ü Straws ü Paperclips ü Rubber bands ü Tape ü Balloons ü Grocery bag ü Popsicle sticks ü Glue ü Paper ü Yarn ü Newspaper- can bring in up to 5 sheets of paper

Testing Analysis § Want to find speed project falls § Know – speed = distance/time – Can measure time with stopwatch § Need to find height of window – Must be able to fall 1 meter without breaking egg

Grade: Criteria Design drawing complete and labeled 20 Design built based of drawing 20 Egg makes 1 meter in tact 20 Evidence of research shown. 20 Explanation of design. How it works, early in model to present what changes you made and why. 20 Did not achieve Achieved goal

Project Design—Group 1 § § § We made the cardboard into a triangular prism. Then we put rubber bands around it. We put the rubber bands in a star shape inside the cup. § Then we put three more near the top with two straws in a “X” shape § Next we put the cup inside of the cardboard and attached a plastic bag to the straws as a parachute § Lastly we surrounded the cardboard in balloons and put one on top of the cup.

Our Outcome § Our egg-drop was a success. § The parachute caught the wind and slowed the structure down. § The balloons cushioned the outside. § The rubber bands in the cup secured the egg from bouncing around § The balloon on the top of the cup served as a lid so the egg wouldn't fall out.

Project Design—Group 2 § We got a box and put a cup in it. § We made a web out of rubber bands on top and bottom to keep the egg from bouncing up and down in the cup. § After that we put two straws on top of each other on the inside of the cup for cushion, and to keep it moving side to side. § Then we put popsicle sticks on the lining of the bag to keep the bag open. § Next we attach the bag to straws to make a Parachute.

Project Design(cont. ) § In our egg drop our rubber bands acted as a seatbelt for the egg. § The cup and the cardboard acted as the outside and inside structure. § The balloons served as a air bag for when it falls

The Results Ø Our egg did not break we feel we should have not made any changes. Why It Didn’t Break Ø It didn’t break because we had balloons around the whole structure and we had a web of rubber bands on top and bottom of the egg. We also line the inside of the cup with straws and we made a parachute. We lined the inside of the parachute with popsicle sticks to keep the bag open. We feel that our project was perfect and it was perfect.

Project Design—Group 3 § Our group decided to place the egg inside of a cardboard box § We placed popsicle sticks on the inside and the outside of the structure § then we glued pieces of cut up straws in the box to cushion the egg (after stretching them) § Then we made a web of rubber bands on top to keep the egg from smashing into the cardboard, and placed on the lid § Then balloons were placed on the out side of the structure to cushion the fall and placed a plastic bag on the bottom to act as a parachute and slow down the structures fall
