I would use the “The Spherical Earth” activity in my classroom to help my students visualize and understand the concept of a spherical Earth. I would begin by introducing the idea that the Earth is a sphere, and then provide students with a ball (or a globe) to physically demonstrate this concept. I would then ask students to work in groups to design and create a model of the Earth using different materials such as clay, paper plates, or Styrofoam balls. This hands-on activity would allow students to visualize the curvature of the Earth and gain a deeper understanding of its shape. Additionally, I would use this activity to tie in with other concepts such as day and night and seasons. The activity would be designed to be fun and engaging, while also promoting critical thinking and creativity.
