In the Salt Water Egg experiment, you have observed that the egg placed in saltwater floated and the one in tap water didn't. Because saltwater is denser than fresh water, the egg does not end up sinking like it usually does!
Why is this so? Let's first discuss the definition of density and why objects sink. Density refers to the amount of matter contained in a given space or volume. When there's more amount of matter in a given space or volume, the object is then considered denser and at the same time heavier. However, this doesn't mean that density and weight is the same and can be used interchangeably.
Weight refers to the vertical force exerted by a mass of object when subjected to gravity. Unlike density, weight is dependent on the amount of gravity in a particular place. To make it clearer, let's take the egg as an example. The egg's density remains the same no matter where you bring it, whatever the amount of gravity is in that place. However, if you bring the same egg to space, where there is no gravity, it loses its weight! But its density remains the same. That's the difference between density and weight - gravity.
Why Objects Float or Sink
Now let's go back to the question of why objects float or sink. Placing an object that's denser than fresh water automatically sinks. In our Salt Water Egg experiment, because the egg is denser than tap water, it pushes away water particles so it can make space for itself hence the sinking motion. But in the case of the salt water, since it is heavier than ordinary tap water, it is more capable of holding the egg up - hence the egg floating. In easier words, objects sink when their own density is greater than the liquid's density.

Corn Syrup Lab Report

this experiment was to find out the effects of different types of liquids on the mass of an egg. My hypotheses were, “If the egg is soaking in water, its mass will decrease because there is a high concentration of water inside of the egg so some corn syrup will diffuse out of the egg.” and “If the egg is soaking in the corn syrup, its mass will increase because there is a lower concentration of corn syrup in the egg so some corn syrup will diffuse into the egg.” The results of this experiment did…

Inaccurate measurements: egg cube cutter not accurate cubes meaning different volumes of cubes (not all 5mm by 5mm) Temperature of water in the beaker wasn’t stable due to the external environment. The 5ml of HCL was not accurate with the pipette as it was difficult to grasp the needed amount. The 10ml of Pepsin solution “ “ Using a stopwatch was more accurate as opposed to counting. Improvements that could have been made: Kept the water stable in the beaker…

Research Investigation On Osmosis

the process in which water moves across a semi-permeable membrane and goes to the higher concentration of solute.1 2.2. Important factors to Osmosis and Diffusion include Temperature, Concentration and Surface area to volume ratio. Temperature can affect the rate in which a solute dissolves in a solution, higher temperature faster rate of Osmosis. This is caused by the molecules movements being faster in higher temperatures. Concentrations are…

Egg Osmosis Lab Report

The purpose of this experiment is to see how the functions of an egg relate to an animal cell and also see the effects of the different solutions that are used on the egg during the experiment. Also made a hypothesis on what will happen to cell when it is placed in water by saying it is going to cause the cell to experience osmosis and the altering of the shape of its cell membrane. This was proven wrong because the egg did not alter in shape, all it did was stay the same shape but increase in mass…

diffusion, and osmosis further. Egg one’s circumference ( the long way and short way) and its mass will be compared to egg two’s circumference and its mass. In this lab we look at concentration gradient and osmosis. Concentration gradient is the difference in concentration from one place of high concentration to an area of low concentration. In an egg, there is protein, carbohydrates (sugars), and water. We are also studying osmosis. This is diffusion of water. Because of concentration gradient…

Part 1- Testing for Diffusion: A Guided Activity Summary of experiment: The point of the experiment was to see how diffusion works and what it effects. The experiment is tested to see if the solution would be either starch or glucose. Answers of analysis questions: -The starch remains in the dialysis bag because the molecules are bigger than the pores. Also because there is no blue on the outside of the tape. - - record the data every 5 minutes or so to get more data and you can see the diffusion…

Aim: The aim of this experiment is to observe the way the eggs that model cells absorb different liquid concentrations. Hypothesis: The egg will become bigger or smaller in weight and circumference as well as change in color because of the liquid it is in. Equipment: • Vinegar • Salt 50 ml water 250 ml • Food coloring • Coke • Lemonade • Water (control) • Cups (18) • Triple Balance Beam • Tape measure • Paper • Pencil • Gloves (optional) • Graduated…

Essay on Brine Shrimp Habitability

Brine Shrimp Hatchability ABSTRACT Because Mono Lake's salinity dramatically increased, the experiment being conducted is asking, " What is the optimum salinity for the hatching of brine shrimp eggs?" We tested brine shrimp eggs under several circumstances including water that has a salinity of, 0%,2%,4%,6%,8%, and 10%. The results showed that the best possible salinity for brine shrimp to hatch is 2%. In the 10% and 0%, almost no shrimp were hatched at all. INTRODUCTION Mono Lake…

was demonstrated by soaking an egg in various liquids with a time table to see how it would affect the egg. The egg can be substituted as the cell membrane. Predictions, observations, and procedures were made. Before the lab procedures can be discussed, Osmosis and other key terms should be mentioned and explained. Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable (The Egg) membrane from a less concentrated solution, like water into a more concentrated one like…

of diffusion in which water molecules move down the concentration gradient. When the concentration of solute molecules outside the cell is lower than the concentration of solute in the cytosol , the solution outside is hypotonic to the cytosol. If the concentration of solute molecules is higher outside of the cell, the solution outside is said to be hypertonic. The solution outside is isotonic if the concentration is equal on both sides of the cell membrane. The egg shell is made of calcium…
