  • Different Kinds of Materials www.reflectivelearn.com
  • Material Grouping  Material: - The matter of which an object is made is called material. E.g. glass, steel, wood etc.  Classification:- the process of sorting and grouping things according to some basic is called classification. Object can be classified on different basis. i.e. shape, material used, uses etc.  Basis of grouping:- Material can be grouped on the basis of similarity and differences in their property. Different types of material have different properties such as appearance, solubility, transparency, conductivity and behavior towards magnet etc. www.reflectivelearn.com
  • Material Properties  Metallic lustre:- Some material have shine on them called lustre. Material has lustre example gold, silver, copper, while nonmetal has no lustre example gases, sulphur.  Hardness and softness:- Some material cannot be compress and scratched easily and are hard example iron and copper. Some material appears smooth on touching. Example glass.  Smooth and Rough surface: Material, which can be pressed easily are called soft. While some other material which cannot be pressed are called hard. For example: cotton is soft, while wood is hard. www.reflectivelearn.com
  • Material Properties  Solubility:  Soluble:-Substances that are dissolved in water are called soluble substance.  Insoluble:-Substances that are not dissolved in water are called insoluble substance.  Miscible:-those liquid which mix well with water are said to be miscible in water.  Immiscible:-Substances which do not mix well with water are called immiscible in water.  Solubility of gases:-solubility of gases in water is very less. www.reflectivelearn.com
  • Material Properties  Transparency  Opaque:-Materials through which we are not able to see are called opaque e.g. wood, iron, gold.  Translucent:-Materials through which things are only partially visible are called translucent .e.g. Butter paper, old glass door.  Transparent:-Materials through which things can be seen are called transparent. e.g. Glass, water, air. www.reflectivelearn.com
