Planning and Carrying out Investigations

Patterns

Students know:

Properties of matter can be classified as intensive or extensive.
Some examples of intensive properties of matter are, but are not limited to, density, boiling point, and specific heat.
Some examples of extensive properties of matter are, but are not limited to, heat, mass, and volume.
Intensive properties can be used to identify a substance.
Some properties of matter are visible on the macroscopic level, while others are evident at the atomic/ molecular/ particulate level.

Students are able to:

Plan an investigation that outlines the experimental procedure, including safety considerations, how data will be collected, number of trials, experimental setup, and equipment required.
Determine the types, quantity, and accuracy of data needed to produce reliable measurements.
Conduct an investigation to collect and record data that can be used to classify properties of matter as intensive or extensive.
Classify properties of matter as intensive or extensive.
Evaluate investigation design to determine the accuracy and precision of the data collected, as well as limitations of the investigation.
Identify a compound based on its intensive properties.

Students understand that:

Each pure substance has characteristic physical and chemical properties (for any bulk quantity under given conditions) that can be used to identify it.
The data generated from an investigation serves as the basis for evidence.
Macroscopic patterns are related to the nature of atomic/ molecular level structure.
