Cosmic Tapestry
Across
- 3. The force that pushes an object forward, such as the hot gas pushing out of a rocket engine to launch a payload into space.
- 5. The attractive force that pulls objects toward one another, keeping planets in orbit and pulling objects toward the center of Earth.
- 6. An ancient tool used by astronomers and navigators to measure the angle and elevation of stars or the Sun above the horizon.
- 9. A group of stars that forms a recognizable pattern in the night sky, often named after a myth, animal, or object.
- 11. An ancient scientific model that placed Earth at the fixed center of the Universe, with the Sun and planets orbiting around it.
- 12. The amount of matter inside an object, measured in kilograms (kg) or grams (g), which stays the same regardless of location.
- 14. The tendency of an object to resist changes in its state of motion—continuing to move in a straight line unless acted upon by a force.
- 16. The condition in which people or objects appear to be weightless, experienced during free-fall or aboard space stations in orbit.
- 18. The scientific model showing that Earth and other planets orbit around the Sun at the center of the solar system.
- 19. A physical, mathematical, or visual representation designed to help explain, simulate, or predict how a real-world scientific phenomenon works.
- 20. An instrument containing lenses or mirrors that magnifies distant objects in space to make them appear larger and clearer.
Down
- 1. The movement of one celestial body traveling in a complete orbit around another body, such as Earth revolving around the Sun in one year.
- 2. The total cargo or scientific equipment carried by an aircraft or spacecraft, excluding the fuel and engines.
- 4. A star chart featuring two adjustable disks that can be rotated to show which stars are visible in the night sky at any given date and time.
- 7. The spinning motion of a planet or object around its own internal axis (e.g., Earth's 24-hour spin causing day and night).
- 8. The gravitational force acting on an object's mass, measured in Newtons (N), which changes depending on the strength of gravity.
- 10. An event that occurs when one celestial body moves into the shadow cast by another body (e.g., a solar or lunar eclipse).
- 13. The branch of science that studies stars, planets, moons, and other celestial objects in space.
- 15. The regular rise and fall of ocean sea levels caused primarily by the gravitational pull of the Moon and the Sun on Earth.
- 17. The curved path followed by a planet, moon, or satellite as it revolves around a object in space due to gravity.
