An interactive museum of astronomy reasoning instruments.
Explore observables, models, and inferences—like doing experiments on ideas.
Curated concept journeys you can assign or work through in order.
Build foundational astronomy reasoning by linking Earth-sky geometry, measurement, and light into one guided progression.
A broad starter journey covering the core ideas students need before branching into specialized topics.
Build fast intuition for sky geometry by connecting phases, eclipses, seasons, and apparent size in one coherent reasoning loop.
A short starter set for building intuition about sky geometry using a consistent predict→play→explain flow.
Use geometric models to explain changing sky appearances across the Sun-Earth-Moon-planet system.
A geometry-first sequence for stations where students compare multiple observable sky changes using one shared reasoning frame.
Connect orbital patterns to conservation principles and gravitational dynamics across multiple systems.
A progression from descriptive orbital laws to dynamical causes, with enough depth for independent practice.
Interpret conjunction timing as a geometric consequence of relative orbital periods and observer perspective.
A short sequence that builds intuition for conjunctions as a geometric + timing consequence of orbital motion.
Show how light-based observables become quantitative distance, temperature, and composition inferences.
A module-ready path for connecting instrumentation and spectra to the core measurement logic of modern astronomy.
