Standard:
1c Students know metals have properties in common, such as high electrical and thermal conductivity. Some metals, such as aluminum (Al), iron (Fe), nickel (Ni), copper (Cu), silver (Ag), and gold (Au), are pure elements; others, such as steel and brass, are composed of a combination of elemental metals.
Holistic Rating: Moderate coverage of this standard.
| Pages C44-C45 provide the most information for addressing this standard. In terms of physical properties of metals, the California Science Standards specify only high electrical and thermal conductivity of metals. The California Science Framework also mentions properties of shiny (reflect light), malleable (bend under pressure), and ductile (not brittle). |
Aspects that help student learning:
The text describes five properties of metals: have luster (i.e., shiny), are malleable and ductile, and conduct electricity and heat. The activity on pages C84-C85 contrasts the thermal conductivity of metal and plastic.
Aspects that do not help student learning:
The description of alloys is limited to a few sentences. As recommended in the California Science Framework, it is helpful for students to examine samples of different metals and alloys.
The two activities demonstrating electrical and thermal conductivity are located in Chapter 3 (pages C60-96) which focuses on energy concepts. Most of the material in Chapter 3 is not in the Grade 5 standards or framework. The description of thermal conductivity (pages C86-C87) introduces difficult, new concepts (three ways that heat moves) that are extraneous to the Grade 5 standards.
Teacher's Edition that we used cited these pages as addressing this standard, but we did not find a significant correlation:
