• Not Object 1 because it’s made of gas and dust (and orbiting the Sun) implies a comet
• Not Object 2 because it is orbiting the Sun (must be an asteroid)
• Not Object 4 because it is not in space (meteorite?)
• CORRECT ANSWER: Object 3 (a meteor is a streak of light produced by friction with air when an object (rock) from space enters a planet’s atmosphere)

• Option A (kilometer is too small)
• Option B (miles is also too small)
• Option C (Light-year, it would only be a few light minutes between the planets, too large a unit to use)
• CORRECT ANSWER: Option D (Astronomical unit, the distance between the Earth and the Sun, 150 million Km)

3. A student created a graphic organizer below, describing the ultimate fate of stars:
Dwarfstars
Red giants
Super giant
Neutronstar X

• Not Option A (Nebular Star? What the heck is that?)
• Not Option C (A Binary Star isn’t formed as a result of a star dying)
• Not Option D (A supernova can be created when a star dies, but nothing is left -like with a the other options listed)
• CORRECT ANSWER: Option B must be correct. A Black Hole can form at the end of a star’s life cycle.

• Option B is the breaking apart of atoms (the opposite of what happens in stars)
• Option C is not even a real thing
• Option D is not a real thing either
• CORRECT ANSWER: Option A nuclear fusion is the process of atoms fusing together and releasing HUGE amounts of energy.

• It’s not A because it only takes 8 light minutes to get to Earth from the Sun, a light-year is too far!
• It’s not C because a kilometer is way too short…
• It’s not D because the distance is only 93 MILLION miles, not 1 trillion miles.
• CORRECT ANSWER: B 1 astronomical unit is defined as the average distance between the Earth and the Sun.
