Explain the specifics of Jupiter. Talk about how it is a gas giant and is the largest planet in the solar system, as well as having several moons and its own ring system.
Brainstorm out loud with students about what would be needed to live on Jupiter, with a focus on questions that should be considered when creating the alien. Without a solid surface, how would an alien stay afloat? Since there is no oxygen on Jupiter, what would it breathe? Would the alien have consciousness?
Provide material for making the Jupiter alien. The material should be easily manipulated and allow room for maximum creativity. This can include Play-Doh for sculpting the animal or cardboard for cutting out the alien. Also, be sure to get colored pencils or paint for students who want to add color to their Jupiter alien. Before getting material, you can have students brainstorm what materials they need; if you are only working with one child or a small group, you can get each student specifically what they ask for.
Give an example with the material provided. Try to keep your example as broad as possible in order to encourage creativity; however, you should try to emphasize some basic physical aspect that the alien would need to survive specifically on Jupiter, such as wings for floating, as well as the possible color of the alien (such as a reddish hue, as it it reflects Jupiter's surface.)
Have students write a short paragraph with an accompanying visualization of the alien from Jupiter. Encourage them to be as creative as possible; the focus of the assessment should be that they understand the characteristics of Jupiter (large planet made of helium and hydrogen), not that they necessarily create a realistic alien.
