Chapter 4 – Living and Non-living Things

Matter is the nature of any substance on earth and also in the rest of the universe. Matter is a material substance that constitutes the observable universe and, together with energy, forms the basis of all objective phenomena. The three most familiar forms, or states of matter are solid, liquid, and gas. Heating and cooling a substance may change it from one state to another. In this chapter, matter is classified as living and non-living matter.

Chapter 5 – Energy

Energy is required for doing work. It is needed by both plants and animals. While plants need it for food production and growth, animals need it for growth and development. To survive, we need to perform different tasks which include walking, running, singing, dancing, eating, reading, writing, playing, planting, harvesting and carrying things from place to place. As we carry out these tasks, movement is involved, sound is produced, light is needed and used, and we sweat in the process to indicate some heat being produced.

Chapter 8 – Man in Outer Space

Air forms a gaseous blanket over the earth. It is called the atmosphere. The atmosphere is responsible for the weather on earth, and it is an important part of man’s environment. The atmosphere extends to about 900 kilometres from the earth. It is dense, close to the earth’s surface but thins out further away from the earth. Beyond the atmosphere is the outer space. It is vast and without limit and the earth is extremely small in the immensity of the outer space.
