Science is the systematic study of the natural world through observation and experimentation. It seeks to understand how things work, from the smallest particles to the vast universe. Scientists use the scientific method to test hypotheses and gather evidence, leading to discoveries that enhance our knowledge. Engineering applies scientific principles to design and build solutions to practical problems. Engineers create everything from bridges and buildings to software and medical devices. By combining creativity with technical skills, they develop innovations that improve our daily lives and address challenges in various fields, including civil engineering, mechanical engineering, and electrical engineering.
