Science Project Experiment

Question: What type of environment can an egg float in?
Hypothesis: The egg will float in only in hot salt water and the hot contaminated water (cooking oil).
Materials: 3 Uncooked Eggs
3 Paper cups
2 Tablespoons
Salt
Cooking Oil
Cold and Hot water
Procedure: 1. Pour cold water into the 3 cups.
2. Add a tablespoon of salt to cup 2 and a tablespoon of cooking oil into cup 3.
3. Put one egg and each cup and watch the eggs or 5 minutes to see if they float.
4. Record data.
5. Repeat steps 1-4 with hot water.
Data:
Regular Water Contaminated Water Salt Water
Cold Water Egg did not float Egg did not float Egg did not float
Hot Water Egg did not float Egg did not float Egg Floated

Results: Only the egg in the hot slat water floated. All of the other eggs sank straight to the bottom.

Conclusion: The hypothesis was partially correct because the only the egg in hot salt water floated but the egg in hot contaminated water did not. The topic of the experiment relates to the results because the results shows just what type of environment an egg could or could not float in. An egg is like a human body with the liquid inside of it and the protective outside. Like I stated in my abstract paragraph with the little Israeli boy when there is a lot of slat in the mixture of the water it can cause you to float for a very long time. The hot water melted the salt into the mixture of the water while the salt in the cold water had just sunk to the bottom. Possible sources of error could be the temperature of the water. Also the cooking oil or salt in certain environments could have affected the results of the experiment.
