OSMOSIS EGG EXPERIMENT

PURPOSE

• Observe the effect of vinegar, corn syrup, and water on an egg.
• Relate this to osmosis in cells.

MATERIALS

• Eggs
• 2 beakers
• Vinegar
• Corn syrup
• Water
• Triple beam balance
• Measuring tape

HYPOTHESIS

DAY 1 MEASURMENT

• Egg in vinegar
• Mass 58.7 g
• Circumference 14cm

DAY 1 QUESTIONS

• Remove the egg from the outer shell
• The shell will dissolve and become soft

OBSERVATIONS DAY 2

• The egg was put into water
• Mass 58.3g
• Circumference 14cm

DAY 2 QUESTIONS

• It increased because the vinegar absorbed into the egg
• I think the egg will stay the same
• I think the egg will get smaller

Data table

OBSERVATION DAY 3

• The egg in beaker 1 will increases the water went inside
• The egg in beaker 2 got smaller because the water went outside
• Osmosis means delusion of water

EXTRA CREDIT

• It is made of millions of smaller molecules that create a flexible and porous container. Proteins and phospholipid make up most of the membrane structure
• 2 small and non polar hydrophobic molecules can freely pass through the membrane
