The Alien Egg Experiment

Hank Green introduces SciShow experiments, focusing on osmosis, a key process in cellular water absorption. Using an egg as a model, he demonstrates how osmosis works by dissolving the egg shell with vinegar, allowing water to permeate the membrane. The egg expands due to water absorption. To reverse this, the egg is placed in corn syrup, causing water to exit the egg, demonstrating osmosis in action.

What is osmosis and how does it relate to the egg experiment described?

Why is an unfertilized chicken egg used in the demonstration instead of a human cell?

Describe the chemical reaction that occurs when vinegar is added to the eggshell.

Explain the concept of semi-permeable membranes in the context of the egg experiment.

What happens to the egg when it is placed in corn syrup after being in vinegar?
