What happens to a raw egg when placed in plain water?

• It floats to the top.

• It sinks to the bottom.

• It stays suspended in the middle.

• It dissolves in the water.

Why does the egg sink in plain water?

• The egg is the same density as the water.

• The egg is less dense than the water.

• The egg is more dense than the water.

• The egg absorbs water and becomes heavier.

How can you make an egg float in water?

• By heating the water.

• By adding sugar to the water.

• By adding salt to the water.

• By shaking the water.

What is the purpose of adding salt to water in the experiment?

• To decrease the water's density.

• To make the water taste better.

• To change the color of the water.

• To increase the water's density.

What is the first step in creating a density tower?

• Adding food coloring to the water.

• Layering the water in a container.

• Heating the water.

• Adding salt to the water.

Which color of water is the most dense in the density tower?

• Teal

• Orange

• Purple

• Red

What is the role of food coloring in the density tower experiment?

• To make the water more dense.

• To visually distinguish the layers.

• To make the water taste better.

• To dissolve the salt faster.

What should happen to the orange water in the density tower?

• It should sink to the bottom.

• It should float on top of the red water.

• It should dissolve the salt.

• It should mix with the other colors.
