Liquid Density Experiment Concepts

Hailee Talbot, a fourth-year student at the University of Iowa, guides viewers through a science experiment to explore liquid density. The experiment requires vegetable oil, water, a heavy liquid like glue, and optional food coloring. Hailee explains the concept of density, encouraging viewers to form a hypothesis about the behavior of the liquids when combined. After conducting the experiment, viewers observe the separation of liquids based on density. The video also compares the density of liquids to solids by dropping household items into the mixture. The experiment concludes with a call to continue exploring scientific concepts.

What is the primary purpose of using food coloring in the experiment?

• To make the experiment more fun

• To increase the density of the liquids

• To make the liquids more visible

• To change the taste of the liquids

Which of the following is NOT a heavy liquid option mentioned for the experiment?

• Honey

• Corn syrup

• Molasses

• Milk

How is liquid density calculated?

• Volume multiplied by weight

• Volume divided by mass

• Mass divided by volume

• Weight multiplied by volume

What happens to liquids with lower densities when mixed with higher density liquids?

• They sink to the bottom

• They dissolve completely

• They rise to the top

• They change color

What is a hypothesis in the context of this experiment?

• A detailed experiment procedure

• A random prediction

• An educated guess about the experiment's outcome

• A proven scientific fact

In what order does the narrator pour the liquids into the larger jar?

• Water, heavy liquid, oil

• Oil, heavy liquid, water

• Oil, water, heavy liquid

• Heavy liquid, oil, water

Which household item stayed in the top oil layer during the experiment?

• Plastic bottle lid

• Paperclip

• Coin

• Pop tab

Where did the coin settle when dropped into the liquid layers?

• In the heavy liquid layer

• It floated on top

• In the water layer

• In the oil layer

What is the main takeaway from the experiment on liquid density?

• Density only applies to solids

• Density is irrelevant in science

• Different liquids and solids have varying densities

• All liquids have the same density

What does the narrator encourage viewers to do after learning about liquid density?

• Continue experimenting

• Stop experimenting

• Forget about the experiment

• Only study solid densities
