Introduction to Inquiry - Density, Volume, Mass

A solid rubber ball is cut in half. What is the density of each half?

• Less than the whole ball

• The same as the whole ball

• More than the whole ball

Here are the density of some materials:

Plastic block: 1.0 g/cm3,

salt water: 1.1 g/cm3,

olive oil: 0.9 g/cm3

What happens when the plastic block is added to each liquid?

• It floats in both

• It floats in salt water and sinks in olive oil

• It floats in olive oil and sinks in salt water

Tobias wants to measure the volume of a stone.

Which method will give the most accurate answer?

• It floats in both

• It floats in salt water and sinks in olive oil

• It floats in olive oil and sinks in salt water

A chocolate bar has a mass of 56 g.

The volume of a cuboid is its length x width x height.

Calculate the density of the bar.

• 2 g/cm3

• 8 g/cm3

• 14 g/cm3
