A "lab" is a special place where scientists and researchers conduct experiments and tests. It is equipped with various tools and equipment that help them study different subjects, such as chemistry, biology, or physics. In a lab, you might find items like test tubes, microscopes, and Bunsen burners that assist in exploring the mysteries of the natural world. In addition to scientific research, labs can also be found in schools, hospitals, and even companies. For example, a medical lab analyzes samples to help diagnose diseases, while a computer lab provides resources for students to learn programming and technology. Each type of lab serves a unique purpose in advancing knowledge and innovation.
