Observation#1:Bubbles coming off the egg#2:Eggs float,white stuff on top #3:The skin is gone ,jelly-like and squishy #4 (corn syrup):looks soft,soggy,brown-ish #5:(water) larger and transparent

ConclusionCorn Syrup egg:smaller because:the water went out :the egg had a higher concentration than corn syrup :water moved from higher concentration(egg) to lower concentration(corn syrup)

ConclusionWater egg:larger because:Water entered the egg :The egg had a lower water concentration than the water :The water moved from high concentration(water to low concentration (egg)

• My hypothesis is rightWater eggGain weightGo up in size Look bigger

My hypothesis is right for corn syrup egg

It will look brown-ish

Decrease in sizeDecrease weight
