A Guest Speaker is someone invited to share their knowledge or experiences with an audience, often in a classroom, conference, or community event. They can be experts in various fields, such as science, business, or art, and their insights can provide valuable information and inspiration to listeners. These speakers often engage the audience through discussions, stories, or presentations, making complex topics easier to understand. By inviting a Guest Speaker, organizations can enhance learning and encourage new ideas, helping people to connect with real-world applications of what they study or work on.
