Determine that density is an intensive property of a substance independent of the shape or size of an object.
Determine that density is an intensive property of a substance independent of the shape or size of an object. Through this investigation, students:
- Determine the volume of regular- and irregular-shaped objects using geometric calculations and water displacement methods.
- Use mass and volume data to calculate density using the formula,
density = mass/volume
- Distinguish between intensive and extensive properties.
- Learn that density is an intensive physical property that can be used to identify unknown substances.
Students conduct the following procedures:
- Determine the volume of regular-shaped objects through geometric calculation.
- Determine the volume of irregular-shaped objects through water displacement.
- Measure the mass and volume of various objects and calculate the density by dividing the two values.
- Identify the material a plastic cylinder is made from when given a list of substances and their corresponding densities.
Sensors / Equipment Used:
Investigate density by Archimedes' principle of displacement, specific heats and basic length/volume relationships.
Provides direct volume measurements for materials that displace the liquid for buoyancy experiments.
Graduated cylinder, 50- or 100-mL
Balance - 2 or 3 per class
Metric ruler (or calipers)
Water - 500 mL
The Associated Bundle:
Contains the sensors and probes needed to perform all 17 experiments in the Advanced Chemistry Teacher Guide and all 25 labs in the Chemistry through Inquiry Guide.
