Activity 5.3 Determining Density
Introduction
How full is the bag that you take to each of your classes? Can you put any more stuff into it? What happens to the size of the bag? What happens to the mass of the bag? The size of the bag likely stayed the same, though the bag itself is probably about to burst open. When the volume of something stays the same while the mass increases, then the density increases.
In this activity you will measure volume and mass to determine the density of several objects.

Conclusion
1. How can you use density to identify a material? Density can help identify a material because of the material's mass density which is constant no matter what the volume or mass of the actual material object is.
2. What are limitations of the calculated and indirect volume measurement?
3. Explain the difference between weight and mass. Weight is the amount in lbs. based on gravity and mass while mass is the measurement of an object's volume times its weight density.
