- It is both too hot and too cold for humans to survive on either Neptune or Uranus. Imagine you are planning the first scientific expedition for astronauts to one of these planets. Create a plan for a vehicle that the astronauts could use to navigate through the freezing slushy layers to the scorching hot core.
- It rains diamonds on Neptune and Uranus because of the intense pressure on the carbon in their atmospheres. On Earth, hydrogen and oxygen combine in our atmosphere to form rain water. Imagine far away planets with different elements in their atmospheres. What kinds of strange rain might they have?
