The title of my project is Float or Sink

Question

Back 2

The question I asked was How does different amount of salt in water affect is ability to make an egg float better?

Front 3

Hypothesis

Back 3

The Hypothesis I formed was If you put the saltiest water,then the egg will float better,because salt water makes object float better than tap water.

Front 4

I Researched..

Back 4

Before I did my experiment, I researched the following
1. The ability of an object to "float" when it is placed on water is called buoyant force, and is connected to density.
2.Density consists of how an object's volume and mass are related.
3. The mass divided by the volume accordingly determined gives a measure of the standard density of the object.
Density = Mass/Volume

Procedure

Back 5

The procedure I used to test my hypothesis was to
1.Fill the six glasses half full with tap water.
2.Then carefully place the egg into the first glass.
3.Observe what happens to the egg, and then measure how high it is floating with a ruler. Make sure to measure it by millimeters.
4.Using the spoon, slowly stir and dissolve 1 tablespoon of salt in the second glass of water.
5.Observe what happens to the egg, and then measure how high it is floating with a ruler.
6.Repeat steps 4 and 5 for each of the other glasses, adding 1 tablespoon of salt at a time, until it comes to the top of the glass.
7.Repeat steps 1 through 6, 5 times to be sure your results are valid or accurate.
8.Record all data on a data chart.

Repeated

Back 6

I repeated this procedure 5 times to make certain that my results were valid

Front 7

results

Back 7

the resluts were

Front 8

supported or not supported

Back 8

the results showed that my hypothesis was not supported.

Front 9

conclusion

Back 9

The conclusion I reached was My hypothesis was supported by my data. The more amount of salt in the water affected its ability to make an egg to float better.

Front 10

do this investigation again

Back 10

If I were to do this investigation again,I would float a hollow oject.
