What approach should Carrie take for her rock collection presentation?

Inviting the audience to view the rocks after her speech allows Carrie to keep their focus on her presentation without distractions. It enables a structured flow of information where she can first convey her knowledge and enthusiasm about her rock collection. After her speech, audiences can engage with the rocks at their own pace, which encourages interaction and fosters a deeper understanding of the content presented. This method also maintains the integrity of the presentation, allowing her to emphasize key points without the interruption that passing items around might cause. Additionally, audience members may retain more information when they first listen and then handle the objects, reinforcing their learning experience.
