What Is The Cheerios Effect

In the rubber egg lab also known as the osmosis lab, I first measured the circumference of the egg which was 6 inches. The egg had no cracks and was hard. I placed the egg in the vinegar and within seconds the egg started to bubble. These bubbles were carbon dioxide. After 72 hours the shell of the egg had started to dissolve or flake. This would be considered passive transport as the vinegar diffused across the egg shell without any force. Seventy-two hours into the experiment the membrane was exposed, and had a circumference of 8 inches. Before the egg had a shell and you couldn’t see through it but once the vinegar acted as an acetic acid it broke down the shell and left a yellow membrane that felt like rubber this is an example of diffusion. I then placed the egg in another container and put corn syrup over the egg for 24 hours. The egg had shriveled and shrunk, the water had left the egg and went into the syrup and that is what caused the egg to shrink. The corn syrup is essentially pure sugar with very little water so the osmotic pressure is very low. I then placed the shriveled egg in water and waited for another 24 hours. After observation the egg had no

Hypothesis: If I place an egg in vinegar, then the outer layer of the egg is going to become slimy and look like rubber. It will also become larger and bubbles will form on and around the egg.

This hypothesis is based off of the idea of water density and how it changes when a substance is added or removed. A material's density is defined as its mass per unit volume. It is, essentially, a measurement of how tightly matter is crammed together (Jones, 2015). Every matter in the world has its own specific density. Density can be calculated by multiplying the mass times the volume. Water's density can change when a substance is added or when the temperature is increased or decreased with the normal density of water is just under 1 gram per

Because there is surface tension the water molecules will adhere together to create a skin sheet that can hold the horizontal needle up. The vertical needle breaks through the sheet. If the horizontal needle was wet and to tried to get the needle to float it would not do so. The needles that were dropped horizontally that did not touch the water horizontal would not float because part of the needle is already sinking before the rest of the needle hits the water.

Attraction between water molecules which allows insects and other objects to float a top the water

When an object falls onto the surface, it has to push the water molecules apart. If the effect of the weight of the object is insufficient to match the attractive forces between molecules in the surface layer, the object will not enter the surface.

After completing this experiment, our tap water hypothesis was correct, and our saltwater hypothesis was also proven. For the tap water, the gummy bear expanded as we thought it would. This was because of osmosis. The water outside of the bear diffused into the bear from the higher concentration outside into the lower concentration inside of it. The gummy bear was a selectively permeable membrane. This made a hypotonic solution, and the water rushed into the bear, making it get bigger. For the salt water, the bear shrunk as we predicted, also because of osmosis. This was a hypertonic solution, so the water rushed out of the bear, making it smaller. So our hypothesis for both tap and salt water were correct. We carried out the experiment properly

Hypothesis: If 3 drops of soap fit on the penny and 9 drops of water fit on the penny, then the cohesion is water molecules are attracted to other water molecules. Surface tension is the name we give to the cohesion of water molecules at the surface of a body of water. Independent Variable: This is the one you're changing in the experiment, so it's the type of solution that you're dropping on the penny.

Buoyancy the ability or tendency to float in water or air or some other fluid. I will tell you about an upward force of the fluid which resists the weight of immersed objects. The density of the atmosphere depends on the altitude. Can you tell me about buoyancy in simple words? It tells you about the ability of an object to float on the water or liquid. You can determine whether the object will float or not by checking the relation between the weight of the water and the weight of the

7. Could this property of water explain why a small paper clip can float on water in a glass that is so full that the water is just about ready to spill out? Explain. A small paper clip can float on water in a glass that is so full that the water is just about ready to spill out since the amount of mass of paper clip is inferior than it resembles to

This, of course, is due to the effects hypertonic state holds on the egg because there was such a high concentration of syrup outside of the egg versus the inside of the egg where there was very little. This provoked the water to move out of the egg and into the cup where the syrup

kong, R.P. Singh, 2016. Now let’s talk about why the three other gummy bears that were put into baking soda water, fanta soda, and water expanded and got softer. I believe that this has to do with the glucose, starch, and gelatin, I think this because these three ingredients are all able to absorb water and within those 24 hours there was a different amount in water in those containers than in the salt water container because the salt water didn’t absorb any water so it’s water level was higher than that of the other three. I got this information from a pdf by Emily Grimm. My hypothesis was proved right and wrong because I predicted that the gummybear would either dissolve or enlarge, I was right because the gummy bears mostly enlarged and as they were set out on our napkins they started to come apart, you could say that I was only half right because one of the gummy bears decreased rather than enlarged and that one stayed whole but I would count this as win because it was mostly right. The experiment doesn’t stop there, of no, there is still more to investigate such as, what if you tried a different gummy or maybe not even a gummy at all, what about a small part of apple or a grape cut in

Osmosis is a form of diffusion that occurs when there is movement of molecules across a cell membrane in liquid. With the lab one will be able to see the size of three gummy bears change due to being soaked in multiple types of water overnight. Each gummy bear's mass and volume are recorded, and then placed in a beaker of tap, sugar, or salt water. The following day all three gummy bears are taken out to be remeasured after to see the effects on it from osmosis happening. In all of the gummy bears, both the mass and volume increase, resulting in the size of the bears to increase. The bear with the most percentage of change in mass and volume is the one in tap water. The least amount of change in mass and volume occurs in the cup with salt

Each bubble of casein has a light negative charge. Negative charges are repelled so the bubbles of casein do not bump into one another. Because acid was added the milk gains a small electrical charge. When small amounts of positive charge are floating in the milk, the bubbles no longer repel so they bump together and stick. Instead of microscopic bubbles of protein we have the curds. The reason that the fat that was extracted sat on top of the water is because water is polar and the fat is

not float like a balloon or sink below the line and should be formed from the top and not the bottom.
