Transcript of Floating Egg Experiment

Floating Egg Experiment Introduction How does egg float, stay in the middle or sink in the water? I have conducted this experiment to show the state of an egg in a tap water container, less table salt with water container and more table salt with water container. Materials 3 containers
3 raw eggs
Table salt
Tap water
Procedures Fill the three containers with tap water.
Label the three containers with 1, 2 & 3.
Add 2 tablespoon of table salt in container 2 . Then add 4 tablespoon of table salt in container 3 and stir it well with a tablespoon until the salt has completely dissolved in the water.
Place one egg in each of the containers and observe which one of the eggs float in the container, stay in the middle and sink in the water. Results In the container 1, the egg has more density than water so it sinks.
In the container 2 with less table salt, the density of water matches the density of salt and the egg is in equilibrium
In the container 3 with more table salt, the egg is lighter so it floats in the water. Conclusion The hypothesis which I concluded was false because the egg can also float and stay in the middle of the water because the denser the liquid the easier the egg can float in it.
Hypothesis I think that the egg will sink no matter what will be added to the water because it is denser than the water itself. Variables The dependent variable is the container
2 and container 3.

The independent variable is the amount
of salt in the containers.

The control group is the container 1. Graph
