ANDOVER – Ninth grade students at PV HS did their best not to crack under pressure as they dropped eggs from the school wrestling loft on Friday, March 3, as part of a school science experiment. (From March 10 edition of The News).
As explained by HS Teacher Anne Siembor, students in her science class were assigned to come up with a safe package for one medium raw egg and were then asked to drop it from a height of just under 15 feet, which she said would test their knowledge of how to reduce momentum and impact.
Siembor also provided the students rules for the class experiment, which included that the eggs must be easily taken in and out of the package, that the students had a one minute limit on getting the egg into the package, noted that the package must be limited to 18 inches by 18 inches except when including parachutes or propellers, stated that the empty containers must be limited to 600 grams in order to avoid a point reduction and stated that the package could not fly across the gymnasium.
One of the students involved in the experiment included Jacob Edelman.
Edelman said that he used cotton balls to cushion his egg, with straws on the top, along with a garbage bag and shoelace parachute in order to slow it down.
“I put the straws through the top to hold everything in,” said Edelman.
Edelman’s project proved successful, as he was able to drop the egg without causing any cracks.
He wasn't the only one with creative ideas though.
Many other students demonstrated a variety of innovative package ideas for their eggs too, while further supporting and voicing their opinion on their classmates' projects.
“We were learning about momentum and impulse so I had to apply that,” said Alexis Blackburn regarding her drop, which she had tested at home and in class had proved successful. “I expected it to crack [but it didn't].”
Blackburn said her container consisted of a Pringles can that was held together using duct tape and inside of the can squeezed together bubble wrap, a sponge, marshmallows and a shower loofa to cushion the egg.
Other ideas included a cushioned plastic container made by Kari Clute and a Styrofoam, straw, peanut butter and rock concoction assembled by Zoe Haffa.
“I think it’s pretty fun,” said Haffa regarding the egg drop experiment. “It shows everyone’s creativity and what they can put their minds to.”
Aside from the experiment itself, the students were also required to submit a pre-drop report for 50 points in order to explain their design and how it works, needed to document the mass of their package, the time of fall and related calculated quantities, had to explain why their design was successful or failed, plus if it had failed were asked to think about ways it could be corrected.
As stated by Siembor’s guidelines, if a student was successful and did not crack their egg they were awarded 100 points, if an egg was broken/cracked egg they received 80 points and if the student did not show up with a project they did not receive any points.
