Exploring Density Measuring Mass and Volume of Obj
Explore how objects float or sink by measuring mass and volume to find density. Floating objects often have lower density regardless of shape; sinking ones are denser and heavier.

Gizmos
Name: Date:
Student Exploration: Density Laboratory
Directions: Follow the instructions to go through the simulation. Respond to the questions and
prompts in the orange boxes.
Vocabulary: buoyancy, density, graduated cylinder, mass, matter, scale, volume
Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. Of the objects below, circle i » the ones you think would float in water. Click on the image and select EDIT
to use the drawing tool.
2. Why do some objects float, while others sink?
I think some sink because they have to much density
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. A n objects mass is the amount of matter it contains. Mass 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.&g
2. A n objects 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
A. What is the initial volume of water in the cylinder? 400ml
B. Place object 1 into the cylinder. What is the volume in the cylinder now? 414.2 ml
I
C. What is the volume of the object? 14.2
