Osmosis Lab with Eggs

The video tutorial guides students through an osmosis lab experiment using eggs. It begins with preparing the eggs by soaking them in vinegar to remove the shells and expose the membranes. After drying, the eggs' masses are measured before being placed in different sugar solutions to observe osmosis. The solutions vary in tonicity: isotonic, hypertonic, and hypotonic. After several hours, the eggs are re-measured to analyze mass changes, helping students understand osmosis and the effects of different solution concentrations.

What materials are required for the osmosis lab with eggs?
