A science fair is an event where students showcase their scientific projects and experiments. Participants, often from schools, create displays to explain their work, which can involve topics like biology, chemistry, or physics. These projects allow students to explore their interests and learn about the scientific method, including forming hypotheses, conducting experiments, and analyzing results. At the fair, students present their findings to judges and visitors, answering questions about their projects. Awards may be given for creativity, understanding, and presentation skills. Science fairs encourage curiosity and innovation, inspiring the next generation of scientists and thinkers.
