Instructions
- Explore how gravity helps Gravitax move through space.
- Read each question carefully and record your best answer.
- Use evidence from the examples to explain your thinking.
Example: Gravitax drops a ball from a high platform. What force pulls the ball toward the ground?
Answer: Gravity pulls the ball toward the ground.

| ○ C. Earth | ○ D. A grain of sand |
7. Why do astronauts seem to float in orbit?
| ○ A. There is no air anywhere | ○ B. They are falling around Earth |
| ○ C. Their spacesuits push them upward | ○ D. The Sun turns off gravity |
8. Which force keeps the Moon moving around Earth?
| ○ A. Gravity | ○ B. Sound |
| ○ C. Light | ○ D. Friction only |
Part 3: Gravity Checks
Write True or False for each statement.
9. Gravity acts between objects that have mass. True / False
10. Gravity only works during the daytime. True / False
11. A feather and a hammer can fall at the same rate in a place without air resistance. True / False
12. The Sun's gravity helps keep Earth in orbit. True / False
Part 4: Gravitax Missions
Solve each gravity mission and give the answer with the correct unit.
13. Gravitax drops 3 metal balls and then 2 more. How many balls are falling? Answer: __________ balls |
14. A rover weighs 10 units on Earth and 4 units on a small moon. How many fewer units does it weigh on the moon? Answer: __________ units |
15. A probe travels 6 meters downward, then 4 more meters downward. How far does it travel altogether? Answer: __________ meters |
16. Gravitax has 12 fuel cells and uses 5 during a gravity test. How many fuel cells remain? Answer: __________ fuel cells |
Part 5: Explain the Pull (optional challenge)
Answer each question in a complete sentence.
17. Why does a ball come back down after Gravitax throws it upward? |
18. How would jumping change on the Moon compared with jumping on Earth? |
19. Why does a planet with more mass usually have a stronger gravitational pull? |
20. How does gravity help keep Earth moving around the Sun? |
Answer Key
| 1. | gravity |
| 2. | planet |
| 3. | ground |
| 4. | mass |
| 5. | A (It falls downward) |
| 6. | C (Earth) |
| 7. | B (They are falling around Earth) |
| 8. | A (Gravity) |
| 9. | True |
| 10. | False |
| 11. | True |
| 12. | True |
| 13. | 5 balls |
| 14. | 6 units |
| 15. | 10 meters |
| 16. | 7 fuel cells |
| 17. | Earth's gravity pulls the ball back toward the ground. |
| 18. | You could jump higher and stay in the air longer because the Moon has weaker gravity. |
| 19. | More mass creates a stronger gravitational force. |
| 20. | The Sun's gravity pulls Earth toward it while Earth moves forward, creating an orbit. |
