The document describes an experiment to test whether eggs will float in salt water or plain water. The hypothesis is that an egg will float better in salt water because salt makes water denser. The procedure involves placing eggs in glasses of water, one with salt added and one without. It is concluded that the eggs floated in the salt water, supporting the hypothesis.

1. MAKE AN EGG FLOAT IN SALT WATER
BY: GEORGIANA JOSEPH

2. PURPOSE
• THE PURPOSE OF THIS PROJECT IS FIND O
UT WHETHER THE EGGS WILL FLOAT
IN SALT WATER OR IN PLAIN WATER.

3. BACKGROUND
INFORMATION
• WHEN SALT IS DISSOLVED IN
WATER , AS IT IS IN OCEAN
WATER, THAT DISSOLVED SALT
ADDS TO THE MASS OF THE
WATER MAKES THE WATER
DENSER.
• EGGS ARE LAYED FROM
CHICKEN, HENS, AND MORE
ANIMALS.

4. HYPOTHESIS
• MY HYPOTHESIS IS THAT THE
EGG IN THE SALT WATER WILL
FLOAT BETTER BECAUSE SALT
HELPS THINGS TO RISE. FOR
EXAMPLE, YOU ARE COOKING
PASTA, YOU ADD WATER AND
SALT AND THE PASTA. THE SALT
HELPS THE PASTA RISE AND
COOK FASTER.

5. MATERIALS
• TWO EGGS
• WATER
• SALT
• TWO TALL DRINKING GLASSES

6. PROCEDURE
• POUR WATER INTO GLASSES UNTIL
IT IS ABOUT HALF FULL.
• STIR IN LOTS OF SALT (ABOUT 6
TABLESPOONS).
• CAREFULLY POUR IN PLAIN WATER
UNTIL THE GLASS IS NEARLY FULL
(BE CAREFUL TO NOT DISTURB OR
MIX THE SALTY WITH THE PLAIN
WATER ).
• GENTLY LOWER THE EGG INTO THE
WATER .

7. VARIABLES
• THE VARIABLE OF THE PROJECT
IS THE EGGS .THE EGG STAYS
THE SAME.
• THE DEPENDENT VARIABLE IS
THE WATER. THE SALT IS ADDED
IN THE WATER.

8. CONCLUSION
• MY CONCLUSION IS THAT THE
EGG IN THE SALT WATER FLOAT
BETTER THAN THE EGG IN THE
PLAIN WATER. IN ALL THREE (3)
TRIALS,THE EGG IN THE SALT
WATER FLOAT.SO THEREFORE,
MY HYPOTHESIS WAS CORRECT.
