Lesson 5: A Model of the Sun's Interior
This lesson will require approximately one 30-minute class.
- Select and use tools in manipulating materials and in building models (e.g., select appropriate materials to build model constellations)
- Describe the physical characteristics of components of the solar system - specifically, the sun, planets, moons, comets, asteroids, and meteors
Students will build on previous learning to create a three-dimensional model of the Sun with plasticine, identifying six layers of the Sun's interior.
Students will reinforce their understanding of basic colour mixing.
- Visual Arts
- colour mixing
- three-dimensional sculpture
In this lesson, students will build on previous learning to create a three-dimensional model of the Sun with plasticine, identifying six layers of the Sun's interior.
Materials and Resources
- plasticine for each student: one block each of the primary colours, and white
- sharp knives
- black squares of paper for mounting
- white pencils for labelling
- paper clips
- pictures of the Sun's interior, one for each student
- Interior of the Sun applet (Flash Animation)
pictures of sample model, or (preferably) a model completed by teacher
- transition zone
- convection zone
- radiation zone
Developing the Lesson
Distribute pictures of the Sun's interior to students, as well as pictures of and/or actual model of the lesson; discuss layers briefly, as this should be a review of previous learning. Explain the process of today's lesson as follows:
- when all layers have been carefully added and Sun is smooth and round, students should approach teacher for supervised use of sharp knife to cut away approximately 1/4 of their model (in pie shape), revealing the interior layers.
When models are complete, students should each place their artwork on black squares of paper labelled with white pencil with their names. Colour keys should be paper clipped to the black paper to await evaluation.
Evaluation for this lesson should be based upon neatness, adherence to instructions, and accuracy of layers.
