Egg Density Experiment Questions

The video tutorial demonstrates a water density experiment using three glasses of water with varying salt concentrations. The experiment shows how an egg behaves differently in regular water, salty water, and a combination of both. The egg sinks in regular water, floats in salty water, and stays suspended in the middle when regular water is layered over salty water. The video encourages viewers to explain the scientific principles behind these observations.

What materials are required for the water density experiment?

• One glass of water, one egg, and a knife

• Two glasses of water, two eggs, and a fork

• Four glasses of water, four eggs, and a spoon

• Three glasses of water, three eggs, and a spoon

What happens to an egg when it is placed in regular water?

• It dissolves in the water

• It stays in the middle

• It floats to the top

• It sinks to the bottom

Why does an egg float in very salty water?

• Because the egg is lighter than water

• Because the egg is hollow

• Because the salt makes the water denser

• Because the egg absorbs the salt

What is the purpose of adding more salt to the third glass of water?

• To make the water less dense

• To make the water more dense

• To change the color of the water

• To dissolve the egg

What is the expected outcome when an egg is placed in a glass with a lot of salt?

• The egg will sink

• The egg will float

• The egg will dissolve

• The egg will change color

What is observed when regular water is carefully added on top of salty water with an egg?

• The egg dissolves

• The egg floats to the top

• The egg sinks to the bottom

• The egg stays in the middle

What is the significance of the egg staying in the middle when regular water is added on top of salty water?

• It proves the egg is hollow

• It shows the egg is lighter than both layers

• It indicates the egg is heavier than both layers

• It demonstrates the balance of densities

What is the main scientific concept being explored in this experiment?

• Buoyancy

• Density

• Viscosity

• Surface tension

What does the narrator encourage viewers to do at the end of the experiment?

• Try the experiment at home

• Provide a scientific explanation

• Watch another video

• Ignore the results
