Materials & Properties
Category General
Difficulty Level Normal
Audience Level General
Description Materials and their components are described in this course. In addition, Materials’ classification and different kinds of properties are explained. Which properties are changed in nanoscale and the reason of these changes are another subject which are considered in this course.
Overview
In this course, materials and their components are introduced. Components lead to classify materials in different groups. Every group has its specific structure and properties. All of these subjects are explained in this course. Furthermore, in nanoscale, properties are changed. The reason of outstanding material properties in nanoscale is also explained in this course.
 
It should be noted, if material properties are introduced in bulk and nanoscale taking a deductive approach, tangible concepts of structures in nanoscale are gained. Deductive approach enables us to classify nano and bulk materials in our mind.


Booklet
Description
 This lessonis about materials and discusses what is matter. It is not true to call matter everything that we see. For example, we do not see air, but in a balloon, we see that air has mass and volume. To make a precise definition, everything that has mass and volume is a matter.
Mental Challenge
 What are characteristics of matter? 
Quizzes and Activities
 Activity: With a graduated cylinder and a balance, compare mass and volume of a ring and a dice?
