Physics Class - "Egg Drop" Momentum & Energy Project
From Morgan Brown, Physics Teacher:
Physics students finished their unit on momentum and energy by designing and building devices in the classic "Egg Drop" experiment. This experiment required them to build a contraption to hold an egg while it was dropped from a large height, with the goal of having the egg stay intact after impacting the ground. Students were allowed to be creative and use whatever resources they wanted. A number of the students joined the class from home on Zoom, so they created their contraptions and ran their experiment at their homes. Some of the materials used for construction included bubble wrap, sponges, cotton balls, paper propellers, crumpled paper, boxes and bags, and wooden sticks.
The students learned about the relationship between drop height and impact velocity, the relationship between impact duration and distance with the force experienced by the egg, and the various ways to improve the chances of survival. Most students designed an apparatus which both slowed the descent of the egg as well as cushioned the impact. The best designs incorporated both elements. Congratulations to every single student for building successful devices that kept their egg from breaking after being dropped, whether it was on campus from The Justice Center's upstairs walkway at over 5 meters high, or from similar heights by the Zoom students at their homes!
In this week's column, Dr. Grauer asks his students to consider other way to measure their success instead of focusing routinely on their grades.
The Period 7 Theatre Arts class produced a Brown Bag showcase on February 10. Nadia L. '21 and Lourdes F. '22 performed the one-act dramatic play "Poof" by Lynn Nottage during lunch for an appreciative audience on the quad.
The final rounds of the annual Grauer School Spelling Bee took place on February 11, when 7th and 8th graders competed to decide who will qualify to represent Grauer at The San Diego Union-Tribune Countywide Spelling Bee on March 17.
The Pre-Calculus class went to the beach on February 11 to evaluate their ability to write trigonometric equations from data found by observing the breaking waves. The students found the mathematics in something they love and appreciate... while having fun!
Thank you to all of our wonderful Grauer parents for their contributions to the Faculty & Staff Appreciation Luncheon on February 12!
Courage is the unwritten core value that Grauer students are using to get through this pandemic. Dr. Grauer reflects that he never realized how courageous it is just to live life in joy, in smiles, in song, and in play.
