Magic Floating Egg Lab Report
The Amazing Floating Egg
By:

Introduction:
My name is Madison Johnson. I am in the 9th grade. I am in Mrs. Logan’s biology class. I am doing my project on “The Magic Floating Egg”. Eggs sink in normal tap water and I am testing whether or not changing the density of water will make the egg float. I was looking at projects on sciencebuddies.org and I saw that multiple people had done this. I am trying to prove that when you add a certain amount of salt to water, it will make it more dense. I took pictures of the results. This information can be useful because we can test the density of salt water versus the density of normal tap water..

Hypothesis:
Eggs sink in water. I think that
The last jar I filled halfway. One of the full jars I filled with 12 tablespoons of sea salt and mixed it. The other full jar I left with only clear tap water. The jar that was half full I mixed in six tablespoons of sea salt. I put an egg in each jar. After I put the egg in the jar that was half full, I filled the rest with clear tap water so that the bottom half was salt water and the top half was clear tap water. I Recorded the results of each jar and took a picture of each. The jar that was only water: the egg went straight to the bottom. The jar that was all salt water: the egg floated on the top. The jar that was half salt water, half tap water: the egg submerged but stayed perfectly between the salt and tap water. If I were to do this project again in the future, I would use multiple mixtures in the water and test which substances were the most dense. Some problems could be that the amount of salt and water can vary and the size and weight of the eggs can also vary. To fix these problems, I could use the same egg for all of the mixtures. I could also do exactly the same amount of water and substances put in the

If you put an egg in tap water, it will sink to the bottom. If you add enough salt, the egg will float to the surface. Density is the mass or volume of an object. It’s easier to think of it as the thickness of the object. Buoyancy is the force that allows an object to float. I performed a fun experiment to see how increasing density of water could make an egg float or submerge. Anyone can do it.…

The hypothesis that was posed was that, “If naked eggs are soaked in two different colors of food coloring for different periods of time, then the mass of the egg will differ, and the red food coloring will make the egg overall bigger than the blue.” However, the data proved that the color of the dye does not affect the osmotic properties of a naked egg in food dye. Both the red and blue food dye at the end of the experiment ended around 100 grams (blue at 99.86, and red at 100.84). By just this, you would tell you that red food coloring caused more of a gain in mass. However, you can tell on the graph above that the increase and decrease of egg mass between days did not differ enough to make that assumption. Because the original red egg was larger at the beginning, this probably explains why it ended up bigger than the blue at the end of the…

For my egg drop project I used marshmallow fluff. I took a little of fluff out and put the egg in. Then I put some more fluff on top of it and compressed it in. When we got assigned the project the first thing I thought of was marshmallow fluff. I wanted something that would hold the egg so it wouldn’t move and break. I also taped the lid with duct tape so the lid wouldn’t fly off or break. The marshmallow fluff is super sticky and thick so I thought it would be perfect to hold the egg in place.…

First, I found two 1litre bottles and marked one with ‘+ salt’ and the other with ‘fresh’. I then went on to add red food colouring to the fresh bottle and yellow to the + salt bottle. The reason for doing so was to establish which ones were which and see if they will successfully float on one another. Secondly, I put 25 tsp of salt into the + salt bottle to improve the density of it (as I was told it would help.) Finally I put the fresh bottle on top of the + salt, making sure I didn’t spill too much in the process.…

My results to my findings to my brine shrimp experiment was started on 12-28-15, using 4 jars. Each jar contained water, salt, and brine shrimp eggs. I started by filling each jar with tap water and then adding salt. I added 1 TSP of salt and each jar added ½ TSP more of salt. In my experiment I noticed on the first day, 12-28-15, in all the jars the brine shrimp eggs were added to the 4 jars. Some observations I noticed were the eggs didn’t sink right away, they stayed on the surface for awhile. On the second day, 12-29-15, in jar 1 85% of the brine shrimp eggs hatched. In jar 2 75% of the brine shrimp eggs hatched. In jar 3 65% of the brine shrimp eggs hatched, and in jar 4 70% of the brine shrimp eggs hatched. All 4 of the jars had the same observations, they didn’t swim gracefully, they were on the side of the jar with more light, and there was still unhatched…

My project is about how much salt it will take for objects to float. In my project I will explain why certain objects float while others sink. I took three different objects with different amount of density and put them each in ten cups of water. I then put in teaspoons of water and recorded whether or not the objects floated until all the objects were floating. I was able to see how an objects density affects how much salt is needed to make it float.…

To perform the experiment gloves and safety goggles were obtained. Two decalcified eggs were also obtained from the teacher. Using an electronic scale, the initial mass was measured and recorded of each egg. One egg was then placed in a beaker of distilled water while the other was placed in a beaker of syrup. After a time lapse of ten minutes, each egg was taken out and dabbed to remove excess liquids. After excess liquids had been removed, they were placed on the scale one at a time. The mass was then recorded in a data table. These steps were repeated in ten minute intervals four more times, each time recording the mass in the data table. After all measurements were collected, the percent of mass change was calculated using the formula listed below:…

An aqueous sodium chloride solution was prepared by adding solid sodium chloride to 1500 mL of distilled water while stirring until an uncooked egg floated. The amount of salt added had an unknown mass; however the density was determined indirectly by the use of four different techniques: burette, Mohr pipette, volumetric pipette, and a volumetric flask.…

Is it possible to make an egg bounce? That was the question I asked myself. Is it really possible? An egg seems to be too fragile to do that, but after researching the internet, I have found that some interesting experiments and science fair projects that can easily be done with eggs from the refrigerator. Eggs are not only a source of protein or a part of a delicious breakfast, but eggs can also be used in various science experiments.…
