Scientific thinking is best described as:
- A system of beliefs passed down through generations, unquestioned and unchanged.
- An approach rooted in common observations and iterative experimentation. (correct)
- A rigid adherence to established theories, resisting new observations.

Study Notes
- Astronomy provided ancient civilizations with a way to keep track of time and seasons and was used by some cultures for navigation.
- Scientific thinking relies on everyday ideas of observation and trial-and-error experiments.
- The names of the 7 days of the week are based on the seven naked-eye objects that appear to move among the constellations.
- The Metonic cycle (lunar phases repeating on the same solar dates about every 19 years) can be used to keep lunar calendars synchronized with solar calendars.
- Ptolemy developed a model of the solar system that made sufficiently accurate predictions of planetary positions to remain in use for many centuries.
- The ancient Greeks are recognized for being the first to explain nature with models based on reason and mathematics, without supernatural recourse.
- A geocentric model positions the Earth at the center of the universe to explain perceived celestial movements.
- The Ptolemaic model is an Earth-centered model of planetary motion published by Ptolemy.
- Nicolaus Copernicus created a detailed model of the solar system with the Sun at the center.
- Tycho Brahe precisely observed planetary positions, enabling Kepler to discover the laws of planetary motion.
- Stellar parallax was not observed by Galileo.
- The focus of an ellipse is not always located precisely at the center of the ellipse.
- The force of attraction between objects decreasing with the square of the distance is not a direct consequence of Kepler's Laws.
- Scientific models are used to create testable predictions through observations or experiments.
- The claim that people born when the Sun is in Leo have larger average incomes can be tested scientifically.
- In science, a broad idea that has been repeatedly verified to a high degree of confidence is called a theory.
