Types of Respiration

This chapter explains the different changes that we notice around us in our daily life. These include phenomena such as milk turning to curd, liquid changing to gas and vice versa and changing seasons. The concepts are explained in a lucid manner.

Changes Around Us

In this chapter, we will learn about different uses of forests for human beings. It discusses facts that support forests as a renewable source of energy. Also, we will get information about various things that we obtain from forests.

Forest

The concept of soil and the importance of soil in our life are discussed in this chapter. It describes the soil life chart and the diagram of different types of soil. We will also study the soil horizons and conservation of soil through the activity.

Soil - Our Life

All living things need water to survive. This chapter discusses how much water we use, source of water, water cycle, back to the oceans, what if it rains heavily, how we can conserve water and many factors related to it.

Water

In this chapter, we will discuss the concept of dispersal of seeds in detail. It illustrates the different agents of seeds dispersal. We will also understand the different methods of seed dispersal through the wind, air, and animals.

Seed Dispersal

This chapter describes the reproductive organs in flowers and the parts of a flower. It deals with the classification of flowers on the basis of parts present in them. It also covers pollination, asexual and sexual reproduction in plants.

Reproduction in Plants

In this chapter, we will learn the need for respiration in organisms and the inhaled and exhaled air along with activities. We will also understand the facts related to breathing in plants, different animals, and underwater organisms.

Respiration in Organisms

This chapter gives us a brief description of the nutrition in plants. It illustrates the different types of nutrition, such as autotrophic and heterotrophic with experiments. It also highlights the carnivorous plants and symbiosis.

Nutrition in Plants

From this chapter, we will understand the reflection of light with some activities. It describes the laws of reflection and the types of reflection with the help of a diagram. A brief note on periscope and kaleidoscope are also given here.

This chapter highlights how air exerts pressure and how air expands on heating with the activities. We will learn about the wind, cyclones and the destruction by cyclones. It also discusses some dos and don’ts of cyclones.

Air, Winds and Cyclones

This chapter explains the concepts of electric current, electric circuits and electric resistance. Moreover, it describes the electric potential and potential difference. In addition, it explains the heating effect of current and electric power.

Electricity

From this chapter, we will understand weather and climate. We will learn the various factors and how to measure the components of different weather by using instruments. The effects of weather on our lifestyle are also explained here in detail.

Weather and Climate

The chapter covers the concept of heat and its measuring instruments with the properties of heat and cold. It mentions the degree of temperature including Celsius, Fahrenheit and Kelvin scale.

Heat-Measurement

This chapter describes about the speed of motions of objects. There are different types of motions.

Motion and Time

This chapter deals with the concept of acids and bases. We study how to categorize the substances into acids and bases with some activities and experiments. We learn about acid rains and salts. It also explains the uses of acids, bases and salts.

Acids and Bases

This chapter focuses on the components of food. We will learn about the various nutrients of the food required by our body. It involves some experiments for testing food items. We will discuss the things we need to prepare for our balanced diet.
