Advanced Material Properties
材料特性进阶
Description
Compare and group everyday materials based on advanced properties: hardness, solubility, transparency, electrical and thermal conductivity, and response to magnets
Mastery Evidence
- 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)
Assessment Prompt
Can your child test materials and sort them by whether they dissolve in water, conduct electricity, or are attracted to a magnet?
Prerequisites 4
Testing Materials for Uses
在英国课程体系中,测试材料的高级性质有助于论证材料选择的合理性;而美国课程体系在没有这一先修要求的情况下更早教授材料的用途
Material Properties Vocabulary
按硬度、溶解性、透明度、导电性和磁性对材料进行分类,需要掌握所有这些属性术语
Choosing the Right Material
在测试导电性和溶解性等高级属性之前,必须了解材料的适用性
Solids, Liquids & Gases
理解物质状态有助于测试溶解性等属性
