Chapter-8

PROPERTIES OF MATTER

Class-6

OBJECTIVES

1. Students will be able to know about matter
2. Students will identify the properties of matter
3. Students will be able to differentiate the matter based on the property.
4. Students will be able to know characterise the matter.
5. Students will know about mallability and ductility.
6. Students will reason out the usage of metals in jewellery.
7. Students will be able to identify in their surroundings

Useful Weblinks

Properties of matter
States of matter
Other link about Matter and its states

Concepts

a) Matter b) Elasticity c) Stress and strain d) Malleability e) Ductility


Defination of Mass. Mass corresponds to an idea of how much matter there is in an object. mass is the ammount of matter that something has matter is how much of something that something has

Defination of Matter Matter is the substance of which physical objects are composed,

Matter is any substance made of particles with mass. Matter refers to anything that has mass and takes up space - doesn't refer to any amount Objects that take up space and have mass are called matter. Everything around you is made up of matter. Chocolate cake is made up of matter. You are made of matter. Mass refers to "how much" stuff there is - Ex. 1 gram of suga

Activity.1.

Students will list out the objects Around us .

Multimedia Resources

Activity 2.

Teacher will explain categorise the objects based on shape size and structure through the following questions Differnciate the collected objects according to their colours,texture, hardness,occupation in containers

Activity 3.

Teacher will guide the students to catogorise collected object in three categories

  1. Solid
  2. Liquid
  3. Gaseous

Multimedia Resources

Characteristics and properties of matter

Activity 4.

Teacher shows the arrangement of particals in solid ,Liquid and Gaseous state through diagram with explanation.

LINK States-of-Matter States of matter and partical arrangement in three states can be viewed.Differentation of three states explained clearly.

Elasticity.

Activity 1.

Each Students will be given rubber band and tell them to streach it and slowly release the force and Record the observations . On their observation Teacher will Explain the property of matter i.e Elastacity. Atoms in the rubber band are displaced from their equillibrium position. When streach is stoped energy stored in them bring the atom back to the original position.

Teacher will explain, what is atom, displacement and equllibrium

Multimedia resources

[en.wikipedia.org/wiki/Rubber_elasticity Elasticity]

(Elasticity of some matter is explained with reason in the above wikipidia)

Displacement 

The difference between the initial position of something (as a body or geometric figure) and any later position is called displacement. Equllibrium

The state of a body or physical system at rest or in unaccelerated motion in which the resultant of all forces acting on it is zero and the sum of all torques about any axis is zero.

Matter html m6453fd0a.jpg Elasticity stress and strain

      When a body is deformed  by the application of external forces are brought play with in the body tending to countereact the external forces 

[en.wikipedia.org/wiki/Stress–strain_curve‎ Stress-Strain Curve] ( Elasticity stress and strain and more information will be available in above web address)

Hooke's law — 

A law stating that the strain in a solid is proportional to the applied stress within the elastic limit of that solid.

first stated formally by Robert Hooke (1635-1703) of England in The True Theory of Elasticity or Springiness (1676).

[www.britannica.com/EBchecked/topic/271336/Hookes-l Hooke's-Law] wikipedia/wiki/hook's law More ‎Hook's law's and activity can be viewed along with image.

Malleability Activity 1 Students will collect some thin shining sheets which covers the sweet

Activity 2. Students are asked to visit Blacksmith's work shop and guide them to Report what they observed . Teacher should explain Malleability of a Metal Definition: It is one of the property of the metal(matter) that can be obtaine in the form of thin sheets Matter html m28bf5e06.jpg

Ductility

Activity 1. Instruct the Students to collect Metal Threads of different Electric wires

Activity 2. Visit to a nearest Jewellery shop ,observe and List out Thread like Ornaments.
      Teacher should explain the Ductible property of Metal.
