Instructions & Activity

What is the Sun?

  • Divide students into small groups. Have each group create a model of the sun using different colors of clay to represent each layer. Have students cut their sun in half to expose the layers.
  • Each group will use toothpicks to label the core, radiative zone, convective zone, photosphere, chromosphere, and corona.
  • For each of these layers, students will create a key that describes its characteristics. Students will also list 5 facts about the Sun. Each group will present their information to the class.
