Class 7 Science MCQ Practice

This chapter introduces science as an evolving human effort to understand the natural world. Students learn how scientific ideas develop over time, how observation and inquiry shape discovery, and why science continues to grow through evidence, experimentation, and questioning.

This chapter introduces substances as acidic, basic, or neutral. Students learn how materials show different chemical behaviour, how indicators help identify them, and how these properties appear in everyday substances and practical situations.

This chapter explains electric circuits and the components needed for electricity to flow. Students study cells, wires, switches, bulbs, and complete circuits, and learn how electrical systems work through connection, continuity, and practical observation.

This chapter compares metals and non-metals through their properties and uses. Students learn how these materials differ in appearance, behaviour, and practical applications, and understand how classification helps explain common substances around them.

This chapter studies physical and chemical changes in matter. Students learn how some changes are reversible while others form new substances, and compare daily-life examples to understand how matter transforms in different scientific contexts.

This chapter explains adolescence as a stage of growth, development, and change. Students learn about physical, emotional, and biological changes during this period, and understand adolescence as a natural and important stage in human development.

This chapter explains how heat moves in nature through conduction, convection, and radiation. Students learn how heat transfer affects surroundings, weather, and everyday experiences, and connect thermal movement with natural and practical systems.

This chapter introduces scientific measurement of time and motion. Students learn how motion can be described and compared, how time helps quantify movement, and how observation and measurement work together in studying changing positions and speeds.

This chapter studies life processes in animals. Students learn how animals carry out nutrition, respiration, circulation, excretion, and related body functions, and understand how these processes help maintain life and activity in living organisms.

This chapter explains life processes in plants. Students learn how plants obtain nutrition, transport materials, reproduce, and carry out processes needed for growth and survival, building a clearer understanding of plants as active living systems.

This chapter explores light through shadows, reflection, and visual effects. Students learn how light travels, how shadows form, and how reflection helps us see images, connecting optical ideas with everyday observation and simple scientific explanation.

This chapter studies Earth, the Moon, and the Sun as a connected astronomical system. Students learn about their motions, relationships, and observable effects such as day, night, phases, and basic celestial patterns that shape human understanding of the sky.
