Key Highlights

Historical Observations: Focus on phenomena such as Moon phases, eclipses, and planetary motions observable without telescopes.
STEM Integration: Combine science, technology, engineering, and math concepts with historical illustrations.
Real-World Context: Emphasize how ancient societies used these phenomena for timekeeping, navigation, and cultural practices.

Introduction

The following ten questions are designed in a PISA-style format and incorporate STEM aspects along with illustrative components. They focus on astronomical phenomena that were recognized by ancient astronomers before the invention of telescopes. Through these questions, students are encouraged to analyze, explain, and apply scientific observations from historical contexts. Each question is accompanied by a scenario, a multiple-choice or open-ended response, and a description of an illustrative diagram or image used to reinforce the concept.

Question Breakdown

Question 1: Moon Phases

Scenario and STEM Aspect

Ancient farmers observed that the Moon went through distinct phases which impacted agricultural cycles and religious festivities.

Question: Explain how the relative positions of the Sun, Earth, and Moon cause the distinct phases of the Moon, and why this cycle takes approximately 29.5 days. Identify the phases as: New Moon, First Quarter, Full Moon, and Last Quarter.

Illustration: A diagram showing the positions of the Sun, Earth, and Moon during each phase along with arrows indicating the orbital motion.

STEM Focus: Astronomy and Earth Science.

Question 2: Solar Eclipses

Scenario and STEM Aspect

Ancient observers regarded solar eclipses as rare and dramatic events which had significant cultural impact.

Question: Define a solar eclipse and describe the necessary alignment of the Sun, Moon, and Earth. Explain why total solar eclipses do not occur every month.

Illustration: A simplified diagram showing the Moon blocking the Sun, with the shadow cast on the Earth. Highlight the difference between partial and total eclipses.

STEM Focus: Physics and Astronomy.

Question 3: Lunar Eclipses

Scenario and STEM Aspect

During lunar eclipses, ancient astronomers noticed that the Moon could take on a reddish hue, inspiring various cultural interpretations.

Question: Describe the phenomenon of a lunar eclipse, including why the Moon can appear red. What role does the Earth’s atmosphere play in this observation?

Illustration: An annotated image illustrating the Earth’s shadow on the Moon, with a focus on the red tint caused by the scattering of sunlight in the Earth’s atmosphere.

STEM Focus: Physics, Earth Science, and Astronomy.

Question 4: Naked-Eye Planets

Scenario and STEM Aspect

Ancient sky watchers noted the “wandering stars” that moved differently than the fixed stars, which we now know as planets.

Question: Identify the planets that are visible to the naked eye (Mercury, Venus, Mars, Jupiter, and Saturn). Explain how ancient astronomers could distinguish these moving points of light from the more static stars in the night sky.

Illustration: A diagram or painting depicting the night sky with labeled planets and the background of fixed stars to emphasize their motion.

STEM Focus: Astronomy and Navigation.

Question 5: Rising and Setting of the Sun

Scenario and STEM Aspect

Ancient civilizations relied on careful observation of the Sun’s path for timekeeping and for marking seasonal changes.

Question: Describe how the positions of the sunrise and sunset change throughout the year and how this observation helped ancient civilizations construct calendars and determine seasonal cycles.

Illustration: A diagram illustrating the shifting sunrise and sunset positions on the horizon over different times of the year, with arcs demonstrating the pattern.

STEM Focus: Astronomy, Earth Science, and History of Science.

Question 6: Observation of Constellations

Scenario and STEM Aspect

Constellations were not only a mode of organizing the night sky but also served as navigational guides and storytelling mediums in ancient cultures.

Question: What are constellations, and how were they used by ancient observers for navigation and to pass on cultural narratives? Provide an example of a prominent constellation and describe its historical significance.

Illustration: An illustration showing a well-known constellation (such as Orion) with line connections between stars and a brief narrative of its mythological background.

STEM Focus: Astronomy and Cultural Astronomy.

Question 7: Geocentric Model

Scenario and STEM Aspect

Before the heliocentric model became accepted, the geocentric model was the prevailing explanation of the universe, supported by everyday observations.

Question: Explain the geocentric model of the universe, including the observational evidence that historically supported it. Discuss its limitations in explaining planetary motion.

Illustration: A historical diagram showing Earth at the center with planets revolving in circular orbits around it. Include annotations that highlight the strengths and weaknesses of the model.

STEM Focus: Astronomy and History of Science.

Question 8: Time Measurement with Sundials

Scenario and STEM Aspect

Ancient civilizations used sundials as a simple yet effective astronomical tool to measure time based on the movement of the Sun.

Question: Describe how sundials work and explain the relationship between the position of the Sun, the gnomon, and the resulting shadow that indicates time.

Illustration: An annotated diagram of a sundial, showing the Sun's path, the gnomon, and the shifting shadow over the course of a day.

STEM Focus: Engineering, Physics, and Astronomy.

Question 9: Celestial Navigation and Star Motion

Scenario and STEM Aspect

Ancient navigators used the apparent motion of stars to guide their travels by sea. Their observations of star positions made it possible to chart courses long before modern navigation tools were developed.

Question: Explain why and how the motion of stars as observed from Earth can play an important role in celestial navigation. How does the seasonal change of star patterns affect this use?

Illustration: A diagram depicting several constellations with arrows to show the apparent motion over months, with a compass overlay to signify navigation.

STEM Focus: Astronomy, Physics, and Navigation.

Question 10: Retrograde Motion of Planets

Scenario and STEM Aspect

Ancient astronomers were puzzled by the occasional apparent backward motion (retrograde motion) of planets against the background of stars. This observation played a pivotal role in questioning early cosmological models.

Question: Describe what is meant by retrograde motion and explain how this phenomenon was observed without modern technology. How did this observation challenge the prevailing geocentric model?

Illustration: A diagram showing the usual forward motion of a planet on a path interspersed with a segment of apparent backward motion. Annotate the diagram to indicate Earth’s own motion contributing to this perceived anomaly.
