进阶材料特性
Advanced Material Properties
比较日常材料，并根据进阶性质对它们进行分组：硬度、溶解性、透明度、导电与导热性，以及对磁铁的反应。
Compare and group everyday materials based on advanced properties: hardness, solubility, transparency, electrical and thermal conductivity, and response to magnets
学习证据 / Evidence
- 能定义并测试至少四种性质：硬度、溶解性、导电性和磁性。
- 能根据每种性质的测试结果对一组材料进行分类。
- 能利用测试结果解释为什么某些材料会被选用于特定用途（例如，用铜做电线是因为铜导电）。
- Define and test for at least four properties: hardness, solubility, conductivity, magnetism
- Group a set of materials based on test results for each property
- Use results to explain why certain materials are chosen for specific uses (e.g. copper for wires because it conducts electricity)
