Chapter 4: Exploring Magnets explores magnetic properties, functions, and applications of magnets. Some concepts discussed in the chapter are:

• The magnetic compass is a device used by travelers to find directions.
• Materials can be classified as magnetic and non-magnetic materials based on the fact that whether they are attracted to the magnet or not.
• North and South poles always exist in pairs even in the smallest piece of magnet and it is impossible to obtain a magnet with a single pole.
• A freely suspended magnet always rests in the north-south direction and this property of the magnet helps in finding directions.
• Not all magnets are naturally occurring and magnets can be prepared artificially.
• Attraction happens between the unlike poles and repulsion happens between the like poles of the magnet.

Chapter 5: Measurement of Length and Motion highlights the various types of motion a body can experience and the usage of different units to measure the length of an object. Here’s what you’ll learn in this chapter:

• Measurement of the length of objects by using different methods like handspan, cubit, strides, measuring tape, rod, and scale.
• Adoption of SI units for measurement by countries across the globe to simply the process of measurement
• Using different units for measuring different lengths, i.e., larger units like ‘km’ for larger lengths and smaller units like ‘cm’ for smaller lengths.
• The correct way of measuring the length of a curved line.
• Role of a reference point in determining whether an object is at rest or in motion.
• Types of motion i.e. linear, circular, oscillatory, and periodic.

Chapter 6: Materials Around Us discusses how things around us are similar to and different from each other. Topics included in the chapter:

• Classification of objects based on properties like shape, size, color, materials, luster, hardness, and softness.
• Grouping materials as transparent, translucent, and opaque based on whether you can see through them.
• Differentiation of the material based on properties like solubility and insolubility in water.
• All the materials around us are examples of matter and mass is a fundamental property of matter which helps to determine whether an object is heavier or lighter.
• Grouping is essential as it helps you study and observe patterns in the properties of things.

Chapter 7: Temperature and its Measurement discusses determining the hotness or coldness of an object by measuring its temperature and the instruments used for measuring temperature. This chapter delves into:

• Measurement of the hotness or coldness of an object with the help of a temperature-measuring device called a thermometer.
• Kinds of thermometers such as clinical and laboratory thermometers and the purpose served by both of them.
• Proper technique of using a thermometer for noting down the temperature of a body.
• Replacement of mercury thermometers by digital thermometers and infrared thermometers because of their usefulness.
• Different units are used for measuring temperature i.e. Kelvin, Celcius, and Fahrenheit.
• Laboratory thermometer and its temperature range.

Chapter 8: A Journey Through States of Water indulges into different states of water and differences in their properties. This chapter explores:

• The conversion of water into water vapor state is called evaporation and it takes place at all temperatures.
• The conversion of water vapors into water is called condensation and is due to water vapors present in air coming in contact with a cold surface.
• The existence of water in three states—solid, liquid, and gas—and its ability to convert from one state to another.
• The difference in properties of water in solid, liquid, and gaseous states.
• Factors affecting the evaporation process and how evaporation causes cooling.

Chapter 9: Methods of Separation in Everyday Life delves into various methods of separating different components from the mixture and sheds light on when to choose one method over another. Here’s what you’ll learn:

• Handpicking is a convenient method to separate particles from the mixture if they are present in small quantities and can be picked by hand.
• Threshing is the process of separating grains from the stalks.
• The winnowing process of separation is used when lighter and heavier components are both present in the mixture.
• The sieving method is used when the particles that pass through the sieve and the particles that remain on the sieve are of different sizes.
• Other processes, such as evaporation, decantation, filtration, and magnetic separation, are also discussed extensively in the chapter.
• The usage of magnetic separation by industries to separate iron scraps from heaps of waste materials.

Chapter 10: Living Creatures Exploring their Characteristics offers insights into what makes a living being different from a non-living being and similarities shared by living beings with each other. Some key topics covered in this chapter:
