Title: Sideways Uranus


1
Sideways Uranus
  • By

2
Problem
  • How will I investigate why Uranus is tilted on
    its side?

3
Hypothesis
  • I think Uranus got knocked on its side by another
    planet or moon that hit it.

4
Materials
  • The materials I need for my experiment are
  • A large balloon (gas planet Uranus)
  • 1 walnut (the planets rocky core)
  • a tank of gases (Uranus atmosphere)
  • different kinds of balls(moon or something
    that hit Uranus)
  • a laptop and a digital camera

5
Methods/Steps in Experiment
  • Put walnut inside balloon
  • 2. Attach air tank to opening of balloon.
  • 3. Blow up balloon.
  • 4. Try hitting balloon with each of the balls.
  • 5. Observe what happens and take pictures.
  • 6. Write down what happened.
  • 7. Report back to NASA.

6
My Observations
7
Hypothesis I think Uranus is tilted because
something hit the planet and turned it sideways.
  • Conclusions
  • I believe this because when the ball hit the
    gas-filled balloon, the walnut inside it bounced
    and made it stay tilted on its side.

8
Some facts about Uranus
  • Discovered by William Herschel in 1781
  • A very odd planet
  • Orbits the Sun every 84 Earth years
  • Has at least 22 moons.
  • Methane gas gives its atmosphere look
    blue-green.

9
Special Things Ive Learned
  • 3rd largest planet in our Solar System
  • Looks blue-green.
  • Has 18 moons
  • Has rings
  • If Im 75 pounds on Earth, Ill weigh 76 pounds
    on Uranus, so gravity is about the same.
  • 7th planet from Sun.

10
Questions I Still Have are
  • Why is Uranus a giant gas planet?
  • 2. How much gas is there on Uranus?
