Egg Contraptions Lab Report

The science behind this project is conservation of momentum, conservation of energy, force time trade off, and Newton’s first, second, and third laws. These can be used to ensure the eggs safety before, during, and after the egg is dropped. When dropped there are many forces that act upon the egg, some of these are gravity, speed, velocity, and acceleration. When the project is built it is important that this is taken into account. If the science behind all of it is used properly the egg should not break when it hits the ground.

For my egg I took a piece of cardboard and cut it into a small square. Following that I cut three slits in the cardboard in the form of a smaller square. I then took small popsicle sticks and put them into the holes in the cardboard and then hot glued them to the cardboard. To lessen the impact I took rubber bands and attached them across the cardboard from the popsicle sticks. I also did the same on the top with the egg in between. I also slowed the fall by creating a parachute. To make the parachute I cut it out of a trash bag. After cutting the bag I cut six pieces of yarn at eighteen inches each. The I taped the yarn to the bag at even places on the bag followed by the same on the cardboard. When attaching the yarn

Spermatozoa is a system structural motile cells where its formation requires conditions both internally and externally in order to form spermatozoa were able to penetrate the egg perfectly. The purpose of this lab is to determine the shape and structure of some animal sperm. Knowing the normal levels or the presence of sperm and sperm concentration in a single millimeter. The method used is direct observation using a microscope preparation. In human sperm look normal sperm head shape is oval and slightly flattened. Tests on cattle have larger heads than human sperm and more oval. Moving more active than human sperm. Sperm locusts have no means of motion, only a round without any accessory

This study focuses on the means by which a Gallus gallus domesticus egg can demonstrate the process of diffusion and osmosis through a course of distinct chemical changes along with a series of scheduled measurements. Diffusion and osmosis are a critical aspect of human survival and an essential concept for biology-students to understand. Diffusion can be characterized as the irregular movement of atoms, particles, or molecules from a space that has a high concentration to an area with low concentration. In other words, when there is an abundant amount of molecules in a particular area, diffusion helps spread out the molecules until equilibrium is attained. Different elements will affect the rate at which diffusion takes place. The larger distinction

This relates to the egg drop from how they knew that the reaction of the floor hitting the egg, would be equal to the action force of the egg hitting the floor. So they wanted the reaction force to not go directly to the egg, which is why they added the popsicle sticks, so that the reaction force wouldn’t be on the egg it would be on the popsicle sticks. It’s also why they decided to add scraps of paper around the egg thinking that those would also take some of the blow from the reaction force. Though that extra weight was their downfall because it just made the action force more which made the reaction force more because of Newton’s 3rd law which states the action and reaction forces are

Osmosis is a slow passive transport process, by which of water from a lower solute concentrated environment to a greater solute concentrated environment through a semipermeable membrane. The solute is the substance that dissolves in water, such as sugar, or salt (Dalton, 2016). The total concentration of solute in a solution is described as tonicity. According to Khan Academy, there are 3 kinds of tonicity that solution a solution can have (Osmosis and Tonicity, 2016). The first one is isotonic, which is when the extracellular fluid has the same solute concentration as the cell, and thus there will be no net move of water in or out of the cell. When the cell has less solute concentration than the extracellular fluid, the extracellular fluid is described as hypertonic relatively to the cell, and the net flow of

An egg is a fragile object that breaks when a small amount of force acts upon it, but many people have tried to prevent it from breaking when it falls by building contraptions for it. The egg drop experiment is generally used as an experiment to teach students about the concepts of physics. There are many ways to prevent an egg from breaking when it falls. One example is to use a parachute to slow down the descent of the egg. Another example is to wrap the egg in bubble wrap to cushion the egg’s landing. The technique you decide to use determines the results that you get. I have always been interested in doing an egg drop experiment because it involves building and dropping things. For my first MOS project, I decided to build different contraptions

In this essay, the physics behind dropping an egg from a balcony without breaking it will be discussed. The final prototype consisted of multiple thick straws sticking out from a pyramid of 3 inch straws which held the egg. Starting with the pyramid, 3 inches were cut from the regular straws and attached with glue and tape to make a hollow pyramid shape. The regular straws were then attached to the pyramid to make them stick outward. To secure the object, tape was wrapped all around the straws that were sticking out. Altogether, straws, glue, and tape were used.

“How would you make a successful Egg Delivery Module?” When I was asked this question in science, I believed an Egg Drop Module would be easy to create. I was very wrong, though. The Egg Drop Module that my group constructed was not successful in keeping the egg safe. This is because of not anticipating the length of the drop and how hard the Egg Drop Module would hit the ground. If we had made changes, our module would have worked much better.

An egg has the capability of withstanding a large amount of force as long as the force in distributed evenly around the egg. For example, an egg can be thrown like a baseball and sometimes the egg won't break if it lands from a high toss into grass. When the force of an egg is focused at one point it will break but if it is evened out around the egg, the egg has a higher chance of not breaking. Along with evening out the force, it will also benefit the egg if the impact is decreased with the help of outside objects surrounding the egg. The structure should absorb and deflect the force of impact. The design should lift the egg up allowing the structure around it to take some of the impact before it reaches the egg. Which will increase the likelihood that the egg will not break.

Okay drag is basically like when you throw a rock or anything and it’s attached to a balloon and or something that kinda floats and it goes down slower . Air resistance plays a massive point in dropping items because sometimes if the item that your dropping is big it might fall faster because the air doesn’t have enough power for the item. One way that I think will help the impact is to put rubber bands on all the sides and lift the roll cage for the egg a bit higher than the bottom of the machine so it won’t hit the

The gametes used are from the species Strongylocentrotus purpuratus. Sea water containing unfertilized eggs was collected and four experimental conditions were applied. Before applying the treatments to the eggs, sea water was incubated in 16ºC water for 10 minutes. In the first experimental condition, 1mL of seawater was collected as a negative control. In the second experimental condition, 1µL of sperm was added to 1mL of sea water, as a positive control. The third condition contains 1mL sea water and 5µL of Ca2+ ionophore (A23187) prepared as a 1mM stock in DMSO. A23187 is a hydrophobic compound responsible to facilitate the diffusion of Ca2+ from the endoplasmic reticulum to the cytosol. DMSO is a substance used to add hydrophobic compounds to cells, since it is miscible in hydrophilic and hydrophobic solutions. The last condition contained 1mL of sea water and 5µL of DMSO, which works as a

The forces acting on the egg as it falls was gravity. In order to control the force, we must make the falling time longer to decrease the force. From seeing our and other group’s egg drops, the cotton balls helped reduce the impact. Most groups also used either a cup or a cardboard box. Layering the egg didn’t have much of a role depending on the person’s design. My egg wasn’t completely layered because all we add was one sheet of plastic wrap on the top of our cup. Some eggs cracked when they were a box filled with tissue. My partner and I knew that in order to stop the egg from cracking was to increase the time of the fall. We decided to add tissues and place it in a cup. On our test run the egg cracked because it hit the floor. To prevent

The reason a egg can float in saltwater is that saltwater has a higher density than freshwater. The density increases with salt concentration, so the amount of salt you need might depend slightly on the egg. A good starting point would be 6 tablespoons of salt in 1 glass of water (make sure it is fully dissolved by stirring). If the egg does not float, just add some more salt.

Abstract: Different environments have different effects on the mass of an egg. This was tested by placing the egg in vinegar, corn syrup, and tap water. The vinegar increased the mass, the corn syrup decreased the mass, and the tap water increased the mass. This is due to the different concentrations of each substance and the process of osmosis. Particles of higher concentration move to regions of lower concentration.
