   Pull-arrow diagram

   Two balls a set distance apart; four change cards beside them.

2. 1.

   Esme starts with two balls a set distance apart. Which change makes the pull between them strongest?

   • Paint both balls a darker color so they look heavier
   • Keep the masses and move them apart
   • Double both masses and move them closer
   • Halve both masses and move them apart
3. 2.

   Starting from the same two balls, which change makes the pull between them weakest, by Jun's reasoning?

   • Same mass, but closer together
   • Make both balls warmer so they pull less on each other
   • More mass and closer together
   • Less mass and farther apart
4. 3.

   “Drawing, not to scale:” Luz's friend says there is no gravity in space, and that is why astronauts float. Which response is best?

   • Agree: astronauts lose their mass in space
   • Disagree: astronauts float because they are lighter than air
   • Agree: space is too far for gravity to reach
   • Disagree: gravity there is about 90% as strong; they float because they fall
5. 4.

   A video says heavy things fall faster than light things even with no air at all. Milo checks it. Which response is best?

   • Agree: more mass means a faster fall, air or no air
   • Disagree: light things fall faster when there is no air to slow them
   • Agree: the Apollo 15 hammer beat the feather
   • Disagree: without air, objects fall at the same rate
6. 5.

   Noah's cousin says a small rock does not pull on Earth at all. Which response is best?

   • Agree: just the bigger object pulls
   • Agree: small things like rocks have no gravity of their own
   • Disagree: the rock pulls Earth harder than Earth pulls it
   • Disagree: the rock pulls Earth with equal force; Earth barely moves

7. Table (NASA Planetary Fact Sheet), NASA values, with columns Planet, Mass (10²⁴ kg) and Gravity (m/s²)

   Earth, mass 5.97 (×10²⁴ kg), gravity 9.8 m/s²; Jupiter, mass 1,898 (×10²⁴ kg), gravity 23.1 m/s²; Saturn, mass 568 (×10²⁴ kg), gravity 9.0 m/s².

   Using the NASA table, about how much would Pia's 12 lb backpack weigh at Jupiter's cloud tops?

   • About 12 lb, since mass stays the same
   • About 28 lb
   • About 3,800 lb, since Jupiter has 318 times the mass
   • About 5 lb, since Jupiter is so far away from the Sun
9. 7.

   And at Saturn's cloud tops, about how much would the same 12 lb backpack weigh, using the same NASA table, by Ren's math?

   • About 11 lb, a little less than on Earth
   • 0 lb, since Saturn is made of gas
   • About 1,140 lb, since Saturn has 95 times the mass
   • About 12 lb, since weight stays the same everywhere
10. 8.

    Earth 9.8; Pluto 0.7. A 30 kg box sits first on Earth and then on Pluto, where gravity is 0.7 m/s². What stays the same, and what changes, says Tala?

    • Both drop to zero once the box reaches faraway Pluto
    • Both stay just the same
    • Its mass stays 30 kg; its weight on Pluto is much less
    • Its mass drops on Pluto; its weight stays the same
11. 9.

    Ari's model shows Earth's pull on a ball getting stronger as the ball moves farther away. What is wrong with it?

    • Heavier balls should fall faster in the model
    • The arrows should get shorter as the ball moves away
    • Nothing; farther away means a stronger pull
    • The ball should feel no pull from Earth
12. 10.

    Poster drawing with the words "On the Moon, you have less mass." A space-camp poster says, "On the Moon, you have less mass." Which fix does Bo suggest?

    • You have more mass on the Moon, since you can jump higher there
    • You have less weight on the Moon; your mass stays the same
    • Nothing; mass changes with gravity
    • You weigh nothing on the Moon
