Prior Knowledge Questions (Do these BEFORE using the Gizmo.)

1. Of the objects below, circle the ones you think would float in water. If you cannot circle

themon your computer, simply type the names here: the beach ball

2. Why do some objects float, while others sink? The mass of an object will determine if it

willsink or float. The more mass that an object has, the greater possibility that it will sink.

The lighter an object is the less possibility it will sink and greater possibility it will float.

Gizmo Warm-up

The Density Laboratory Gizmo™ allows you to measure a variety of

objects, then drop them in water (or other liquid) to see if they sink or float.

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 g

2. 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 ina

graduated cylinder. Place object 1 into the Graduated Cylinder.

What is the volume of object 1? 14.0 cm3

Note: While milliliters (mL) are used to measure liquid volumes, the equivalent unit

cubic centimeters (cm3

) are used for solids. Therefore, write the volume of object 1 incm3

.

3. Drag object 1 into the Beaker of Liquid. Does it sink or float? Object 1 sunk to the bottom

ofthe beaker of liquid.
