Activities
- Define mass.
- Define volume.
- Define density.
- Calculate: A rock has a mass of 50 grams and a volume of 10cm3. What is the density of the rock?
- An unknown object is placed in water and it floats. What can you infer about the density of this object compared to water?
- During a classroom experiment, one large object and one small object were placed on a table before being placed in a tub of water. One student made the claim that small objects will always float, and large objects will always sink. Do you support or refute his theory? Support your answer.
Answer Key/Rubric
- Mass is the amount of matter in an object.
- Volume is the amount of space an object takes up, measured in cubic units.
- Density is the relationship of mass and volume. If mass and volume are known, density can be calculated by dividing the mass by the volume.
- The density is 5g/cm3. (50÷10=5)
- The object is less dense than water, which is why it floats.
- Acceptable responses must include, but are not limited to:
- Statement of how buoyancy is related to density, not mass.
- Sample Response: Whether an object floats or sinks in water is not based on its mass. It is based on its density. Density is the amount of mass per cubic unit an object occupies. The density of mater is 1 g/cm3. If the density is greater than this, it will sink and if it is less, it will float. The mass AND volume would need to be known to calculate the density, and whether it floated or sank would not be reflective of its size.
