why did our egg crack? Going into the egg drop project our group felt confident due to an abundance amount of research each one of us had done. Our cradle consisted of an inner tetrahedron base, using clear straws that were taped together holding the egg inside within the zip lock bag. The outer part of our cradle was formed by a full straw being cut in half then taped side-by-side, increasing the strength of the straws, then tapped at the vertices of our tetrahedron; facing the opposite direction of the egg. Rubber bands were then wrapped around the center of the entire model, further holding the straws in place. The three main forces to consider in this project were gravity, air resistance, and impact. Gravity pulled our cradle toward
The purpose of this project was to understand the forces, momentum, and energy a contraption would experience during an impact from a pendulum at 5, 10, 15, 20, and 25mph. The project was required to hold and protect 2 raw large Grade A eggs from each pendulum impact respectively.
As I was doing research on this assignment I came across a web page about the effects of gravity on mars as it specifically relates to the projectile path of a curve ball. I know that you cannot believe everything you read, especially when it comes to internet content, but the issue is still worth noting. I will mention this effect when the topic of spin on the ball is discussed. Gravity was the other force that was mentioned by the scientists. This isn’t too particularly exciting, because it’s always in
... reproduction for understanding human reproduction, using computer programs and 3-D model. There has been a lot of research on how the egg binds with the sperm. The main evidence uncovered to support the main body of the article was observing the chicken reproduction to show how the egg was fertilized.
The Purpose of this lab is to use the impulse and momentum concepts to explain what happens when the eggs are dropped onto various objects.
Kinematics unlike Newton’s three laws is the study of the motion of objects. The “Kinematic Equations” all have four variables.These equations can help us understand and predict an object’s motion. The four equations use the following variables; displacement of the object, the time the object was moving, the acceleration of the object, the initial velocity of the object and the final velocity of the object. While Newton’s three laws have co-operated to help create and improve the study of
“How about we use a pulley system with a weight at the end to push the car forward?” my team member suggested. “Or we could use a hammer launcher,” I proposed. We went back and forth, contemplating different methods. We faced trials, tribulations, and troubles in the design process. Building and perfecting our designs took weeks, but our coach guided us throughout the process and encouraged us to “Never give up!” We researched the effects of different factors that could potentially come in the way of our success and analyzed all of the device possibilities. Even when research got arduous and we couldn’t agree on something, we never gave up on our dream of placing in the regional competition. This was one of the hardest challenges I’ve ever faced in my Science Olympiad career, but our unfaltering dedication and our belief in success helped us persist in the face of setbacks. Once we finished our plan, we began to build the device. It was exhilarating to see our plan come to
Technology: In the hatchery technology was used for things like the Bokanovsky Process (eggs budding process) and the Podsnaps Process (speeding up hatching) (6 and 8). There was also electric-powered systems in the Bottling room (9). Another process that well defines control in a somewhat torturous way was done with technology also, there was a machine that gave different embryos different amounts of oxygen according to what class they were destined for. The less oxygen would go to the Epsilons and Deltas who were meant to be the dumbest. They were also put to near death when being dosed with alcohol as a part of the Bokanovsky Process. All of those machines and processes control how the babies turn out. After the Hatchery the babies go into the Con...
Background info: hypertonic solution was used in the lab, hypertonic is the liquid substance that is going out of the egg. When a red blood cell has more water than what's outside then the water will come out and will become smaller. Hypotonic is when the water on the outside of the cell has more water than the inside, the water will go in the inside to make it run smoothly. Isotonic is when the inside and outside of the cell is each, they will stay the same.
how wonderful it would be to make some device which had even the possibility of ascending to Mars, and how it would look on a small scale if sent up from the meadow at my feet. . .It seemed to me that a weight whirling around a horizontal shaft, moving more rapidly above than below, could furnish lift by virtue of the greater centrifugal force at the top of the path. I was a different boy when I descended the tree from when I ascended, for existence at last seemed very purposive.” (Yost, 145)

During the first day, we weighted the egg and put the vinegar in the cup. Then, we let the vinegar sit on the egg for 24 hours. The next day ,day 2, we spilt out the vinegar ,and added distilled water. We also weighted the mass of the egg ,and described the appearance of the egg on the data chart.
Now that you know a little more about my topic, I will go back through all my ideas. I will use some sort of protective material to help prevent the egg from breaking. Once I find what will best protect the egg, I hope that stores will cover/wrap eggs in the protective surface. This will help prevent the eggs from breaking in the containers.
In this experiment we learned about equations which will give us an answer to the following situations such as; object is free falling and a car which is moving on a linear track. We also learned that these equations will give us the distance traveled, the time it took to travel, the initial velocity where it started from, and the instantaneous velocity of the object. We have also learned that acceleration is referred to gravity (g) which is 9.8m/s^2 when dealing with free falling object. The purpose of this experiment is to calculate average acceleration and gravitational

The gravitational force at the surface of the planet is the force that binds all bodies to earth, this force is one of the four forces recognized by physicists, and this kind of force is known as "gravity" it attracts every celestial object to earth, and though it is the most important of the forces essential for our lives, it is the least comprehended of them all Throughout ages scientists have tried to solve the mystery of gravity, and one of the first discoveries concerning gravity was made by Aristotle who concluded from his experiments that the downward movement of any body is that has weight had a proportional relationship between its quickness in motion and its size. However this theory was accepted for centuries, but after a series of experiments made by Galileo, Aristotle's theory was proved to be incorrect, as Galileo said after a series of experimenting at the Pisa tower that bodies of different sizes fall with the same speed. Later on, the idea that the force is needed so as to change the motion of the body was discovered. After that a great scientist was to improve all the previously accepted theories, this scientist was Newton who was to make decisive advances in understanding gravity. In his first law Newton said that a body in state of rest or uniform motion in a straight line will keep on moving unless acted upon by a force, while in his second Newton expressed his first law in a more quantitative way as he said that force acting on a body is the rate of change of it's momentum which can be put in a rule as F= ma Where (F) is the force acting on the body while (a) and (m) are the acceleration and inertial mass of the body respectively. Newton also made the law of gravitation in which he expressed the gravitational force of attraction between any two bodies acting along the line joining them as Where (m) is the mass of the two bodies and (r) is the distance between them, while (G) is the proportionality constant known as the constant of gravitation, afterwards Newton made his very important assumption in which he showed that the inertial mass of a body is identical to its gravitational mass which implied that the gravitational force exerted on or by an object is directly proportional to its inertia.
