Density Laboratory Gizmos Part A Warm-Up-3

Gizmo Warm-Up

1) An object’s mass is the amount of matter it contains. The mass of an object can be measured with a calibrated scale like the one shown in the Gizmo. Drag the first object onto the Scale. (This is object 1.)

What is the mass of object 1?

• 19.5 grams

• 29.4 grams

• 9.4 grams

• 10 grams

Gizmo Warm-Up

An object’s volume is the amount of space it takes up. The volume of an irregular object can be measured by how much water it displaces in a graduated cylinder. Place object 1 into the Graduated cylinder. (Notice the pin that holds the object in place so it doesn’t sink or float.)

What is the volume of object 1?

• 14.0 ml or cm^3

• 19 ml or cm^3

• 17.4 ml or cm^3

• 4.2 ml or cm^3

Drag object 1 into the Beaker of liquid. Does it sink or float?

• sinks

• floats

• both

• neither

What is the mass of object 2?

• 11.0 g

• 19.0 g

• 33.4 g

• 9.5 g

What is the density of object 3?

• 9.4 g/cm³

• .80 g/cm³

• 24.2 g/cm³

• 17.4 g/cm³

What is the density of object 4?

• 28.9 g/cm³

• 19.3 g/cm³

• 2.9 g/cm³

• 18.3g/cm³

Does object 5 sink or float?

• sinks

• floats

• both

• neither

What is the density of object 6?

• 2.7 g/cm³

• 4.9 g/cm³

• 29.3 g/cm³

• .4 g/cm³

What is the density of object 7?

• .10 g/cm³

• 100.3 g/cm³

• 9.4 g/cm³

• 7 g/cm³

What is the density of object 8?

• .92 g/cm³

• 24 g/cm³

• 26 g/cm³

• 2.25 g/cm³
