Day 1: Introduction to the Night Sky & Basics of Astronomy + Getting to Know the Meteor Shower


Lecture Topics (Approx. 2–2.5 hours):

● What is astronomy? How is it connected to our daily lives?

●Classification of celestial bodies: differences between stars, planets, moons, asteroids, comets

● Origins and naming of constellations (including Greek mythology)

● Introduction to the Perseid Meteor Shower: timing, causes, observation tips

●Using constellations to locate Polaris and understanding seasonal constellation changes

● Famous astronomers and the scientific revolution: how Galileo changed the world with a telescope

● Key figures: Galileo, Copernicus, Newton

● Earth’s rotation and revolution: causes of day-night and seasonal changes


Activities (Approx. 1–1.5 hours):

● Use Stellarium software to locate constellations

●Make a constellation viewer (black paper + flashlight)

● Group artwork “My View of the Meteor Shower” and identifying the location of Perseus

Day 2: Introduction to Astrophotography & Meteor Shower Observation


Lecture Topics:

● Basics of astrophotography: camera types (DSLR/mirrorless), lenses, tripods

● Settings for night sky photography: ISO, shutter speed, aperture; what is long exposure and why a tripod is necessary

● Teaching basic camera settings: how ISO, shutter speed, and aperture affect images

● How to assess light pollution and choose the right time/place to shoot

● Mobile phone photography tips: using night mode and stabilisers

● Forecasting the Perseid peak and planning for photography

Suggestion: Students are encouraged to bring cameras and tripods. Smartphones, iPads, etc., are also welcome for participation.


Activities:

● Daytime: practice with equipment—composition, focusing, exposure simulation experiments

Evening Special Event: Perseid Meteor Shower Observation at Lake Fairfax Hilltop Group Campsite

○Guided long-exposure photography or visual observation and meteor count logging

○ Photography guidance


Day 3:Telescope Operation & Solar System Exploration


Lecture Topics (Approx. 2 hours):

● Principles and uses of different types of telescopes (refracting, reflecting, radio)

● Overview of the solar system: structure and orbits of terrestrial vs. gas giant planets

● Mars vs. Venus: geology, atmosphere, life detection challenges and trivia

● Tips and common mistakes in using telescopes (e.g., image inversion, magnification issues)

● How NASA probes study alien atmospheres (with greenhouse effect experiments)


Activities:

● Make a paper telescope and practice distant viewing outdoors

● Use NASA Eyes or Solar System Simulator to explore the planets

● Game: teams race to find planets using Stellarium – fastest team wins

Evening Special Event: Community Stargazing in Virginia

Day 4: Exploring the Moon & Future Lunar Missions


Lecture Topics (Approx. 2 hours):

● Basic lunar features: types of terrain (maria, craters, highlands) and their origins

● Phases of the Moon and tides: with models and diagrams

● Three major moon formation theories: Giant Impact, Capture, Co-formation

● Review of lunar exploration: Apollo missions, Chang’e missions, Artemis Program

● Discussion on future lunar bases: energy, water, and human habitation challenges


Activities:

● Use GlobeViewer Moon App to virtually explore the Moon’s terrain

● Group project: design a future moon mission (mission goals, payload, robotic design)

Evening Special Event: Community Stargazing in Maryland


Day 5:Solar Observation & The Future of Astronomy


Lecture Topics (Approx. 2 hours):

● The Sun’s five layers: core, radiative zone, convective zone, chromosphere, corona

● Solar phenomena: sunspots, flares, prominences, solar wind

● Impacts of space weather: GPS disruption, auroras, solar storms

● Light pollution and dark-sky preservation: advocacy by International Dark-Sky Association

● Future astronomy missions: James Webb Space Telescope, Mars base concepts

● Overview of space policy and international cooperation (briefly covering NASA, ESA, CNSA, etc.)


Activities:

● Draw a cross-section of the Sun + solar observation using filters (weather permitting)

● Group design presentations: “Future Deep Space Missions”

● Closing ceremony: showcase projects, issue certificates, group photo

Special Afternoon Event: Optional Solar Observation at the National Mall (weather-dependent)
