NAME_____________________ EGG OSMOSIS LAB EGG MEASUREMENTS: Egg in sugar water Egg in distilled water Mass of egg at start (g) Mass of egg (g) after 24 hours Mass of egg after 48 hours Total change in mass (g) Use + if it got bigger Use – if it got smaller Egg Observation What happened to the egg that sat in the sugar water for 2 days? Grew bigger What happened to the egg that sat in distilled water for 2 days? Grew bigger Shrank smaller Shrank smaller USE THE DIAGRAMS BELOW THE ANSWER THE FOLLOWING: (Black dots represent solute in a solution) A B Which diagram represents the egg in sugar water? Which diagram represents the egg in distilled water? C A B C A B C The sugar water solution was _______________________ compared to the egg. hypotonic hypertonic isotonic The distilled water was _________________________ compared to the egg. hypotonic hypertonic isotonic Stayed same size Stayed same size CHECK THE “FISH” DEMO: What happened to the “fish” in salt water? Grew bigger Shrank smaller What happened to the “fish” in distilled water? Grew bigger Stayed same size Shrank smaller Stayed same size USE THE DIAGRAMS BELOW THE ANSWER THE FOLLOWING: (Black dots represent solute in a solution) A B Which diagram represents the “fish” in salt water? C A B C Which diagram represents the “fish” in distilled water? A B C The salt water solution was _________________________ compared to the “fish”. hypotonic hypertonic isotonic The distilled water was _________________________ compared to the “fish”. hypotonic hypertonic isotonic
