Osmosis and Egg Experiment Concepts

The video demonstrates an osmosis experiment using eggs, vinegar, corn syrup, and water. Initially, eggs are placed in vinegar to dissolve their shells, leaving only the membranes. On the second day, the eggs are placed in different solutions: one in corn syrup and the other in water. Observations are made on the third day, showing that the egg in water grew due to water moving into it, while the egg in corn syrup shrank as water moved out. The video concludes with an explanation of osmosis and a fun test to see if the eggs bounce.

What was the purpose of using vinegar in the osmosis experiment with eggs?

• To make the eggs float

• To change the color of the eggs

• To cook the eggs

• To dissolve the eggshells

What were the two solutions prepared for the osmosis experiment?

• Milk and juice

• Saltwater and sugar water

• Vinegar and oil

• Corn syrup solution and plain water

After 24 hours in vinegar, what was the condition of the eggs?

• They were hard-boiled

• The shells were completely dissolved

• They turned green

• They became smaller

What was observed about the egg placed in corn syrup after 24 hours?

• It turned into a solid ball

• It dissolved completely

• It shrank and became squishy

• It became larger and firm

Why did the egg in tap water grow larger?

• Because the water concentration was higher outside the egg

• Because the water concentration was higher inside the egg

• Because the egg absorbed sugar

• Because the egg was heated

What is the role of solute concentration in the osmosis experiment?

• It determines the color of the solution

• It affects the movement of water across the egg membrane

• It changes the temperature of the solution

• It makes the egg float

What happened to the egg in the corn syrup solution in terms of water movement?

• Water moved into the egg

• Water evaporated from the egg

• Water moved out of the egg

• Water did not move at all

What was the final observation about the egg in water?

• It turned into a solid ball

• It dissolved completely

• It grew larger and firm

• It became smaller and squishy

What was the purpose of placing a spoon over the egg in the corn syrup solution?

• To prevent it from floating

• To make it dissolve faster

• To keep it warm

• To change its color

What was the final fun demonstration with the eggs?

• Freezing them

• Painting them

• Cooking them

• Testing if they could bounce
