I would choose the “Spherical Earth” activity for my classroom. This activity offers a really engaging way to introduce the concept of Earth’s shape to young learners.
I would start with a class discussion about what the Earth looks like. Students often have preconceived notions, such as a flat surface and create a KwL chart on a large sheet that we can come back to at the end of the activity.
Next, I would introduce the concept of a sphere using everyday objects like balls or oranges. Students can explore these objects, discussing their shape and characteristics.
For the main activity I would have the children create a model of the Earth. Students could use balloons or Styrofoam balls as the base. They could then decorate them with continents, oceans, and other features using markers or paint.
