Purpose:
To explore the concept of density by using a virtual lab to measure
several objects' mass (gram scale) and volume (graduated cylinder
using liquid displacement).
Setup:

to start the Explore Science Virtual Density Lab
Procedure:
- Adjust the Density (g/cc) slider switch under the Pail of
Liquid to 2.0 g/cc
- Place each of the 10 objects on the Scale and in the Graduated
Cylinder recording their mass and volume respectively in a data
table similar to the one below
- Compute the density of each object and determine if each will
sink or float in the Pail of Liquid (2.0 g/cc)
Data/Analysis:
| Object |
mass(g) |
volume(ml) |
density(g/ml) |
sink or float? |
