Density Cubes

Objective: Identify five unknown cubes by determining their densities.

Sample Problem –

Cube A

Height – ______Width – ______Length – ______

Volume – ______Mass – ______Density – ______

Which material below is the sample cube? Circle it.

Material / PVC / Nylon / Brass / Copper / Aluminum / Acrylic / Oak / Pine / Poplar / Steel / Polyester
Density
(g/cm3) / 1.39-1.42 / 1.1 / 9.2 / 8.8 / 2.7 / 1.2 / 0.75- 0.90 / 0.875 - 0.95 / 0.35 – 0.50 / 7.8 / 1.5

Independent Practice

1. With your lab group, determine the physical properties for each cube. They have been labeled cubes 1-5.

2. Fill in the data table as a group. The volume you found for cube A is the same for all the volume. Fill them in!

3. To determine the density, use the formula ______.

Cube Number / 1 (black) / 2 (grey) / 3 (clear) / 4 (metallic bronze) / 5 (wood)
Volume / 15.625 cm3
Mass
Density

What are the cubes’ identities? 1- 4-

2- 5-

3-

Analysis

1) If Mpg means miles that can be gotten per gallon of gasoline and Mph means milesthat can be gotten in an hour. What does g/cm3 (read as grams per centimeter cubed) mean? ______

______

2) Which cube (1-5) has the most amount of matter? Explain your answer.

______

______

3) Which cube (1-5) has the least amount of matter? Explain your answer.

______

______

4) If one cm3 is equal to one ml, calculate the density of a half liter bottle of water that masses 20g.

______

______

5) Create a BAR graph showing the densities of the objects. Make sure your graph talks: Title, axis numbered, labels, key, scale is correct.
