The Rubber Egg Experiment and Osmosis

The video tutorial demonstrates osmosis using a rubber egg experiment. It explains how to remove an egg's shell with vinegar, creating a semi-permeable membrane. The egg expands as water from vinegar enters it. Safety precautions are discussed. The experiment is extended by placing the egg in corn syrup to deflate it, and then in water to rehydrate it, illustrating osmosis principles.

What is the primary process being demonstrated in the rubber egg experiment?

• Condensation

• Diffusion

• Osmosis

• Evaporation

What safety equipment is recommended during the rubber egg experiment?

• Safety glasses

• Lab coat

• Gloves

• Face mask

What happens to the egg after being soaked in vinegar for 24 hours?

• It dissolves completely

• It becomes larger and bouncy

• It remains unchanged

• It becomes smaller

What is the purpose of placing the rubber egg in corn syrup?

• To observe osmosis causing deflation

• To make it sweeter

• To harden the egg

• To change its color

What is observed about the corn syrup after the egg is placed in it?

• It becomes more viscous

• It becomes less viscous

• It changes color

• It evaporates

What is the expected outcome when the deflated rubber egg is placed in water?

• It dissolves

• It remains deflated

• It changes color

• It rehydrates and becomes rubbery again

What does the final experiment with water demonstrate about osmosis?

• Osmosis only works with vinegar

• Osmosis can reverse the deflation

• Osmosis is irreversible

• Osmosis only works with corn syrup
