SC15.5.3
Examine matter through observations and measurements to identify materials (e.g., powders, metals, minerals, liquids) based on their properties (e.g., color, hardness, reflectivity, electrical conductivity, thermal conductivity, response to magnetic forces, solubility, density).

Knowledge
Students know:
- Materials have different properties-color, hardness, reflectivity, electrical conductivity thermal conductivity, solubility, and density.
- Measurements of a variety of properties can be used to identify materials.
- Measurements should be made in standard units (e.g., grams & liters).
Skills
Students are able to:
- Identify the phenomenon through observations about materials, including color, hardness, reflectivity, electrical conductivity, thermal conductivity, response to magnetic forces, and solubility.
- Identify the evidence and collect data about the observed objects in standard units (e.g., grams, liters).
- Collaboratively plan the investigation.
- Identify materials based on their properties.
Understanding
Students understand that:
- Standard units are used to measure and describe physical quantities of materials such as weight, time, temperature, and volume. These measurements will assist in the identification of the materials ( e.g. powders, metals, minerals, and liquids).
