STEM FAIR PROJECTProject title: FLOATING EGG

Student Name: Jacob Aryee

STATEMENT OF THE PROBLEM• Which solution will cause an egg to float?

RESEARCH• Eggs :

– Contain all of the good protein, vitamins and minerals we need except Vitamin C

– China produces the most eggs: 160 Billion per year!

– A hen can produce 250 eggs per year

– White shelled eggs come from hens with white feathers and white ear lobes

– Brown shelled eggs come from hens with red feathers and red ear lobes

– Eggs help our eyes so that they will not become weakened with cataracts (lutein)

VARIABLES• Controlled variables: Amount (1 cup) of

liquid, size of container (tall glass, 5 ½ inches deep), length of time in liquid (10 seconds), 1 egg (medium sized egg)

• Independent variable: Floating ability.

• Dependent variable: The solution as different variables were added to make up the solution

HYPOTHESIS• I predicted that the egg will float in milk

because the yolk of the egg floats in the pancake mix my mom makes with milk.

MATERIALS• 1 medium sized egg

• 1 tall glass

• A cup of fat free organic milk

• A cup of carbonated water

• A cup of salt water (1 cup of water and 1 teaspoon of salt)

• 1 standard ruler

• iPhone to take pictures

PROCEDURE• Pour 1 cup of water and a teaspoon of salt into the glass

• Carefully place egg in the glass and Observe for 10 seconds

• Measure to see if egg floats

• Record Data

• Remove egg from glass

• Empty and rinse glass

• Pour 1 cup of carbonated soda into the glass

• Carefully place egg in the glass and Observe for 10 seconds

• Measure to see if egg floats

• Record Data

• Remove egg from glass

• Empty and rinse glass

• Pour 1 cup of milk into the glass

• Carefully place egg in the glass and Observe for 10 seconds

• Measure to see if egg floats

• Record Data

DATA/OBSERVATIONS

• Note: In milk, I believe the egg sank because I heard a 'clank' sound like it hit the bottom of the glass. But we were not able to see the egg in the glass because milk is not a clear liquid. Because we could not prove that the egg did or did not sink using our tools, we decided not to include milk in our result set since the experiment was inconclusive.

CONCLUSION• The results indicated that an egg can and

will float in salt water. The egg floated 4 inches from the bottom of the glass!

TOOLS
