The Class 7 NCERT Science book – Curiosity provides engaging chapter overviews that make learning easier and more interactive. Each overview gives a quick summary of key concepts in physics, chemistry, and biology, helping students revise faster and build a clear understanding of the topics.
This is the very first chapter of the NCERT class 7 science book, which tells us that science is not just a fact but about asking questions and exploring the world around us. t talks about simple things like melting ice, batteries, growing plants, and light and shadows. The chapter helps students think like scientists and stay curious.
This chapter teaches students how to use indicators such as litmus paper, turmeric, red rose extract, and more to determine if a substance is acidic, basic, or neutral. It describes the behaviour of various compounds, their typical applications, and how neutralisation facilitates day-to-day living. The ideas are simple and engaging to comprehend, with entertaining experiments and real-world applications.
Using cells, wires, bulbs, and switches, this chapter teaches students how electricity moves through a circuit. It describes how to check whether materials conduct electricity, create basic circuits, and create circuit diagrams using symbols. Learning about electric circuits is made simple and engaging through engaging activities and real-world applications.
The physical and chemical characteristics of metals and non-metals, including malleability, ductility, conductivity, and reactivity, are explained to students in this chapter. It illustrates how various materials react to heat, electricity, water, and air using practical examples and easy exercises. The significance and common applications of metals and non-metals are also taught to the students.
Students learn how to observe and identify chemical and physical changes in daily life in this chapter. It describes how some changes, like melting or folding, are physical and don't create new substances, while other changes, like burning or rusting, are chemical and do. In order to assist students in understanding how changes might be beneficial, harmful, slow, quick, reversible, or irreversible, the chapter offers entertaining experiments, activities, and real-world examples.
The changes that take place when children mature into adults are explained in this chapter. Students study emotional changes like mood swings as well as physical changes like height, voice, and look. Growing up, menstruation, nutrition, personal cleanliness, and appropriate social conduct are also covered. The chapter teaches students how to confidently and responsibly navigate adolescence.
Three methods exist for the movement of heat: radiation (through empty space), convection (through liquids and gases), and conduction (through solids). Since metals are excellent heat conductors, cooking is done in metal pans. Both land and sea breezes are caused by convection. Evaporation, condensation, precipitation, and infiltration are all part of the water cycle and groundwater storage.
This chapter discusses how hourglasses, water clocks, and sundials were used to measure time in the past. It also discusses how we calculate speed. Students study the relationship between time and speed in everyday life as well as uniform and non-uniform motion.
This chapter describes how food and air provide the energy that animals need to survive. Using straightforward exercises and examples, it discusses how both people and animals use respiration: the process of using oxygen to create energy and digestion, the breakdown of food.
This chapter outlines how plants perform life functions such as photosynthesis, respiration, transpiration and movement of water and nutrients in order to stay alive.
With real-life examples, students are able to learn the properties of light, how shadows are formed, as well as what reflection is.
This chapter discusses how Earth and Moon interact with the Sun and how these factors affect life on Earth with regard to the formation of the phases of the Moon and eclipses.
