Osmosis and Egg Experiment Analysis

The video tutorial demonstrates an egg osmosis lab over three days. On day one, the egg's shell is dissolved in vinegar to expose the semi-permeable membrane. On day two, the egg is placed in syrup, causing water to move out of the egg, making it hypertonic. On day three, the egg is placed in water, causing it to swell as water moves into the egg, making it hypotonic. The lab illustrates osmosis and the behavior of semi-permeable membranes.

What is the primary objective of the egg osmosis lab?

• To measure the weight of eggs over time

• To observe the effects of temperature on eggs

• To compare different types of eggs

• To study osmosis across an egg membrane

What substance is used to dissolve the egg's shell on Day 1?

• Vinegar

• Syrup

• Water

• Salt solution

After 24 hours in vinegar, what change is observed in the egg?

• The egg shell remains intact

• The egg becomes harder

• The egg changes color

• The egg becomes squishy and the shell is gone

What is the purpose of placing the egg in syrup on Day 2?

• To change the egg's color

• To make the egg sweeter

• To dissolve the egg further

• To observe osmosis in a hypertonic solution

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

• The egg becomes larger

• The egg becomes more solid

• The egg becomes indented and loses water

• The egg remains unchanged

Why does the syrup become more liquid after the egg is placed in it?

• Water from the egg moves into the syrup

• The egg releases sugar into the syrup

• The syrup absorbs water from the air

• The syrup evaporates

What solution is used on Day 3 to observe changes in the egg?

• Salt water

• Syrup

• Regular water with food coloring

• Vinegar

What is observed about the egg after it has been in water for 24 hours?

• The egg shrinks

• The egg changes color to blue

• The egg becomes very full and tight

• The egg dissolves completely

What does the blue color inside the egg indicate?

• The egg absorbed the food coloring

• The egg is dyed blue

• The water moved into the egg

• The egg is spoiled

What term describes the egg's state after being in water?

• Equilibrium

• Hypotonic

• Hypertonic

• Isotonic
