     1. Yarn, fibre and fabric
     2. Natural fibre and synthetic fibres
     3. Cotton bolls and ginning
     4. Spinning, weaving and knitting

Method for Quick Understanding:

To answer all the questions focus on the following points:

a) Differences between natural and synthetic fibres
b) Sources and uses of natural and synthetic fibres
c) Process to separate fibres from plant source (e.g., ginning), process to make yarn from fibre (e.g., spinning) and fabric from yarn (e.g., weaving and knitting)

MERITNATION TIP: a) Do not confuse between different processes and learn properly which process is used for which purpose. b) Learn the processes according to the given flow chart:

Chapter 4 – Sorting Materials into Groups

There are so many living and non-living things around us. We can group them together for convenience and to study their properties. In this chapter things are grouped in different categories on the basis of shapes, colours, uses, materials they are made from etc. There are so many ways to group objects.

Key Points to Revise in This Chapter: 

     1. Properties of materials like hardness, lustre, solubility, floating, sinking, opaque, transparent and translucent
     2. Objects made of single material.
     3. Objects made of different materials.

Method for Quick Understanding: 

a) Listing of different types of objects that are made from the single material or many different materials.
b) Grouping of materials on the basis of similarities and differences in their properties.

MERITNATION TIP:   Pick some of the most important questions that have frequently appeared in the main examinations over the years. These questions are a great way of testing the level of your preparation. Do more practice on questions based on the properties like solubility, opaque,transparent, translucent and floating.

Chapter 5 – Separation of Substances

In this chapter, the different methods to separate components of mixtures are discussed. In some cases only a single method is helpful for separation of a substance while in other cases more than one methods are required.

Key Points to Revise in This Chapter:

     1. Hand picking
     2. Threshing
     3. Winnowing
     4. Sieving
     5. Sedimentation
     6. Decantation
     7. Filtration
     8. Evaporation
     9. Condensation
     10. Solutions
     11. Saturated solutions
     12. Unsaturated solutions
     13. Churning

Method for Quick Understanding: 

a) Develop a clear understanding of which method is used for which type of mixture.
b) Memorise definitions of each method of separation.
c) Understand the principle behind every method of separation.

MERITNATION TIP:  Direct questions appear on defining any method of separation. Generally, mixture of two or three substances are given and you are asked which method can be used to separate them.  So prepare yourself accordingly.

Chapter 9 – The Living Organisms and Their Surroundings

Key Points to Revise in This Chapter: 

     1. Characters of living things
     2. Habitat and its different types
     3. Adaptations to different habitats

Method for Quick Understanding: 

a) Living and non living things can be understood by the same reverse learning technique means first look for the example of a living thing and then take the example of non living thing. Now you can compare the characteristics of both the things to learn better about them.
b) To understand the habitat better you need to see around your school, house and all the places that you visit. You will find different organisms in all of these places. You can understand about how an organism adapts itself to its surrounding by taking example of one organism from each habitat.

MERITNATION TIP:  Characters of living things, different type of habitats and adaptations of different organisms to their habitats are very important topic and you must learn them thoroughly. Once you understand them they are not very hard to learn and you can easily answer the questions about them in your exam.

Chapter 10 – Motion and Measurement of Distances

When you leave your home for school that means you change your position with time. It is said that you are in motion. The length travel is known as distance. This chapter is all about distance, types of motion and their measurement.

Key Points to Revise in This Chapter:

     1. Measurement
     2. Standard units of measurement
     3. SI units
     4. Means of transport
     5. Distances
     6. Motion
     7. Rectilinear motion
     8. Periodic motion
     9. Circular motion

Method for Quick Understanding:

a) Learn 1 m = 100 cm, 1 cm = 10 mm and 1 km = 1000 m
b) Find out standard devices used for measurement.
c) List and observe various kinds of motions occurring around you and identify what type of motions they are.

MERITNATION TIP:  Unit conversion is always asked in exams, so go on practice, practice and practice to convert value in one unit to another form of unit. Solve more and more questions based on rectilinear, periodic and circular motions. Also, remember strongly few examples on each types of motions.

Chapter 11 – Light, Shadows and Reflection

Light has a very critical role in our life. Shadow and reflection are related with light. This chapter includes all these things. There are so many amazing things are related like rainbow that you see in sky after rain.
