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).
