The objective of our project was to design and build a contraption that would secure an egg from breaking upon impact from a second story window‚ and the contraption wieghing as least as possible while falling the fastest. We wanted to design something that would provide a lot of cushioning directly to the egg‚ and also provide extra cushioning to weaken the impact. After testing and submitting a design of just bubble wrap around the egg we found out that it will not be allowed. Due to this we had

In this lesson you will use teamwork to design a container that would protect a raw egg as it falls to the ground from a height of 8 feet. Your team will receive an egg and a bag of materials. You will be given time to brainstorm how you might construct a protective mechanism for dropping your egg without breaking it. You are only allowed to use the materials in your bag within the time frame allotted. It will be important to work well with your teams in analyzing the materials you are given and

Egg Drop (lab writes) In our science class we did an egg drop experiment. We used the scientific method to answer the question and solve the problem. Our question for this particular lab was “will an egg break or be secured‚ if covered with thick sponges and drop from ten feet above the ground?” our idea was to secure the egg from breaking and we wanted to design something that would provide a lot of cushioning directly on the egg. We came up with many different ideas until we choose

The Egg Drop Analysis 1. As far as researching goes I did not do many research besides videos I mainly saw a lot of sponges or big sponges use for people experiment and I in fact went with it and prototypes I used were mainly the same thing with some added cushion to it. 2. I forgot to take a picture but a good description would definitely be a can and thats wrap in cushion on the inside and the outside but the error I made was not covering the metal shock that will it takes impact it release

US had every right to drop the Atomic bomb on Japan and therefore force them to surrender. The Japanese had at that time‚ already lost quite a lot of battles against the US and were forced to retreat back to Japan. Yet‚ the Japanese borders were heavily fortified. Had the Americans attacked Japan‚ they estimated their losses to be about 500 000 men. By dropping the atomic bomb‚ an estimated number of 100 000 people died. So in the end you can see that dropping the atomic bomb has saved quite a lot

The Works Bomb One of the coolest things about chemistry has to be blowing things up. It gives you the satisfaction of knowing your experiment worked (or sometimes failed)‚ plus it’s just a lot of fun to watch something blow up. One of the most popular experiments seems to be the Works bomb. It’s not a “bomb” in the sense that it explodes into flames and leaves a big hole in the ground‚ but it makes an extremely loud bang and steams a little bit. It’s a pressure bomb. The gas created from

dropped a bomb in Japan. The bombing of Pearl Harbor by the Japanese to initiate United States entrance into the war‚ just four years before‚ was still fresh on the minds of many Americans. A feeling of justification and a desire to end the war strengthened the resolve of the United States to quickly and decisively conclude it. President Harry Truman had many alternatives at his disposal for ending the war: invade the Japanese mainland‚ hold a demonstration of the destructive power of the atomic bomb

“What Cousin Tryphena did not know about the way the world outside of Hillsboro was run would have made a complete treatise on modern civilization.
