The Density Tower

The video tutorial introduces the concept of density and demonstrates how to create a density tower using various liquids. It explains the basic physics and chemistry concepts of mass, volume, and density. The tutorial provides a step-by-step guide to building the density tower, including safety precautions and preparation. A bonus experiment is suggested, where the order of liquids is reversed to observe the effects on density layers.

What is the definition of density in physics?

• The volume of an object

• The weight of an object

• The resistance of an object to acceleration

• The mass of an object divided by its volume

Which safety equipment is recommended when creating a liquid density tower?

• Helmet and boots

• Earplugs and knee pads

• Goggles and gloves

• Apron and mask

What is the correct order of adding liquids to create a density tower?

• Start with the liquid with the greatest density

• Start with the liquid with the smallest density

• Add liquids randomly

• Mix all liquids together first

What should you do if the cooking oil layer is not clear initially?

• Remove the cooking oil layer

• Let it settle for a few minutes

• Add more cooking oil

• Stir the mixture vigorously

What is the purpose of the bonus experiment?

• To mix all liquids together

• To observe if the liquids form separate layers in reverse order

• To change the colors of the liquids

• To measure the temperature of the liquids
