Chapter-1 The Unique World of Science
- Introduction to Science: Science is presented as a subject that helps us think, observe, and understand the world by asking questions and solving mysteries.
- Science is everywhere: Science helps explain everything, from the smallest grains of sand to the vast universe and the natural processes that surround us.
- Exploring through questions: Science is about asking questions, making observations, and conducting experiments to find out how things work.
- Atomic Structure and Environment: This chapter throws light upon the Earth’s environment, the diversity of life forms, and the way plants and animals grow and survive.
- Food and materials: The different types of food and ingredients that we encounter every day, such as metals, plastics and paper, have been described, and questions have been raised about their composition.
- Water and Temperature: This chapter discusses water, its various forms (solid, liquid, gas) and how we measure temperature in everyday life.
- Science and daily life: Science is part of everyday problem-solving, such as fixing pens, repairing bicycles, or troubleshooting household objects, following a process similar to the scientific method.
- Scientific method: A step-by-step process used to find solutions to problems by asking questions, making assumptions (hypotheses), testing them, and observing the results.
- Encouragement for Exploration : This chapter encourages students to keep asking questions, stay curious and enjoy learning about science as a continuous adventure.
- Continuous learning : It reminds students that science is a long-term journey, and they will continue to learn new things in the future.
