Experiment:  Egg Drop              


                   

1.        The question:  Will the egg land on the ground without breaking?

2.       Background Information: Eggs break if you drop them.

 

3.       Resources:  blog.mckenzie.com

 

4.       Hypothesis:  If the egg never hits the ground, it won't break.

5.       Planning the Experiment:  We were thinking that we needed a cushion for the egg. We thought that we should suspend the egg in the frame we made.

6.       Performance of the Experiment:  At 10 feet the egg survived. However, at 12 feet the egg cracked.

7.       Data:  10 and 12 feet drop

8.       Interpretation:  At 12 feet, the second drop, the structure collapsed.

9.       Results:  The egg construction survived at 10 feet. However, it did not support the egg at 12 feet.

Experiment:  Straw-Egg Drop Experiment 

1.        The question:  Construct a device meant to hold and protect a large, raw egg that will be dropped from a fixed height onto a target. 

2.       Background Information: egg fragile, straws provide cushion, Popsicle sticks support, tape secures, gravity causes egg to fall faster and force up with impact; need to diffuse impact.

3.       Resources:  15 Plastic straws, 10 Popsicle sticks, 1 m Masking tape, 1 Pair of scissors 1 Large, raw egg

4.       Hypothesis:  Egg most likely will break. :}

5.       Planning the Experiment:  Researched previous designs, discuss/examine what would best protect the egg

6.       Performance of the Experiment:  Egg broke as expected.

7.       Data:  From the height of approximately ten feet the egg was dropped. The egg broke on impact, but the yoke remained intact.

8.       Interpretation:  Egg required even insulation for optimum protection.

            9.       Results:  We failed at protecting our egg. See film. :}

Experiment:  To drop a raw egg from an 8 foot ladder.  

1.        The question:  Is it possible to construct a cradle that will allow our team to drop a raw egg safely from an 8 ft. ladder?

2.       Background Information:   We know that dropping a raw egg from a height greater than a few inches will result in a mess. Our team builder had prior knowledge of the experiment and led our group into our brainstorm session.

3.       Resources:  15 plastic straws, 10 popsicle sticks, 1m of masking tape, scissors, 1 raw egg, flip camera, digital camera, 4 brilliant colleagues.

4.       Hypothesis:  We believe that a raw egg will not survive an 8 ft drop without a support to cushion the blow.  This support will be in two stages.  The outside structure will be made of sticks in a rectangular shape, the interior that will hold the egg inside of the rectangle will be made of straws.  We believe the inside straws will keep the egg from moving while cushioning it against the blow.

5.       Planning the Experiment:  Our team wanted to construct a frame that will support our raw egg.  First we researched prior egg projects on the internet.  We evaluated several websites to find ideas that we wanted to combine into our brilliant design.  Next, we looked at our straws and sticks to determine which should be wrapped around the egg first.  We decided to use our straws to wrap the egg and our sticks to absorb the impact.  Finally we made a practice drop minus the egg to check our plan.

6.       Performance of the Experiment:  Hypothesis was disproved.  Our straws were not secured enough and came apart.

7.       Data:  Egg cracked from the impact of the cement after being dropped from a height of 8 ft.

8.       Interpretation:  With more tape we would have been able to insure that our straws stayed together.

9.       Results:  Disappointment.

Experiment:  Humpty Dumpty Revisited   

1.        The question:  How to protect sweet Humpty from cracking up.

2.       Background Information: We have seen lesser eggs "crack" under pressure.  We believe that Humpty, being an egg with personality, is important enough to protect.  We know that air can act as a cushion and have created a cage to protect dear Humpty, our friend.

3.       Resources:  15 straws, 10 wooden popsicle sticks, a limited supply of masking tape

4.       Hypothesis:  We believe that by creating two triangular prisms out of air filled plastic straws, along with multiple layers of cushioning and a solid platform, we can save Humpty from his untimely death.

5.       Planning the Experiment:  1.  We researched various webites, interviewed a former participant, and collaborated beforehand. 

6.       Performance of the Experiment:  We began by creating triangular prisms out of straws and taping them together.  We then used the wooden sticks to created the platform.

7.       Data:  He survived the fall of ten feet, but a brick wall of thirteen feet proved to be too much for Humpty! 

8.       Interpretation:  Humpty Dumpty should be more careful when he sits on brick walls.  Bad choices can have unfortunate outcomes.

9.       Results:   He's not all he's cracked up to be!  He survived the fall of ten feet, but a brick wall of thirteen feet proved to be too much for Humpty!

Experiment:  Egg Drop                                       

1.        The question:  Can an egg be protected from breaking due to a high drop using straw, sticks and tape?

2.       Background Information: The shell is strongest when pressure is applied on the vertical ends.  

3.       Resources:  10 popsicle sticks, 14  straws, 1 meter of masking tape, 1 extra large egg

4.       Hypothesis:  A cushiony basket surrounded by a frame of sticks will protect the egg from the drop.

5.       Planning the Experiment:  We discussed which supplies would provide the egg with a surface to rest on that would absorb the shock from the drop.  We determined that the straws would be best as they are open and have air flow.  We decided to use all of the straws to build a basket that would cushion the egg.  Then we took the sticks and built a frame.  We thought that a frame may hit the ground first and absorb the shock that the straws and egg will endure.

6.       Performance of the Experiment:  The egg was dropped from about 10 feet.

7.       Data:  The egg did not survive. He suffered a crack on one side.

8.       Interpretation:  We think that a bigger frame may have protected him better. Since the shell is strongest on the top and bottom we think that the egg could have been better protected if he had been turned on his side to secure him in the carrier.

9.       Results:  The egg cracked upon impact. 

Name:  Kim, Nancy, and Tanya

Experiment:  Straw-Egg Drop                          

1.        The question:  Will the egg survive a 10 foot drop without breaking?  14 foot drop?

2.       Background Information: We do not have much background.  However, Tanya was a science teacher. 

3.       Resources:  15 straws, 10 popsicle sticks, 1 yard of masking tape, 1 determined egg

4.       Hypothesis:  If we provide enough cushion, it will absorb the force of the cement hitting the egg;  therefore, the egg will be left unharmed.

5.       Planning the Experiment:  1.  Design an outer, harder frame to hold the egg using the sticks.  2.  Design an inner frame with more give out of the straws.  3.  Use the remaining straws to wrap around all of it.

6.       Performance of the Experiment:  Tanya assembled the contraption.  Nancy experimented with different ways to use the straws and not use up the tape.  She developed the "straw rope".  Kim assisted them, used egg psychology on the egg, and typed the report.  Nancy  also recorded the experiment using the digital camera.  Then we took the egg outside.  Paul climbed a ladder and dropped the egg from 10 feet.  Then he moved up a couple of steps and dropped the egg from 14 feet.

7.       Data:  After falling from 10 feet, the egg had no apparent injuries.  After falling from 14 feet, it developed a small leak on the bottom of the egg; however, the yolk remained intact.

8.       Interpretation:  The egg needed more protection on the bottom after the first fall.  We had three straws protecting it, but the egg pushed through those straws during the first drop.  Therefore, the egg was no longer cushioned from the outside, harder frame. 

9.       Results:  Our structure worked well during the first drop.  However, it sustained damage and was compromised during the second drop.

Experiment:  Egg Drop                                       

1.        The question:  Can we build a structure that will protect an egg from breaking when dropped from a height of 10 ft.?

2.       Background Information: We know that eggs break easily and are subject to the laws of gravity.

3.       Resources:  Tape (measured),  1 raw egg, limited # of straws, wooden sticks (see previous), scissors, cameras.

4.       Hypothesis:  Straws wrapped securely around the egg then reinforced with wooden sticks taped t/o will successfully protect the egg from breaking.

5.       Planning the Experiment:  1.  Insert the straws from end to end.  2.  Wrap the "long straw" around the egg.  3.  Lay tape on flat surface.  4.  Place wooden sticks on top of tape (reserve 2 sticks for later).  5.  Utilize the rest of the tape by cutting in half.  6.  Lay one stick on top of the structure & one on bottom (in an "x" fashion).  7.  Use the remaining tape in an "*" fashion.  8.   Ready for testing!!!!!

6.       Performance of the Experiment:  The first successful drop was from 10 ft.  Three groups were left and went to the second drop of 12 ft.  The last round our group was the lone survivor. 

7.       Interpretation:  The design was successful after multiple drop attempts.

8.       Results:  WE ARE the CHAMPIONS!!!!!!
