Astronomy club activities for school students

The best astronomy club activities do two things at once: they are fun to make, and they measure something real. These are the builds and sessions the Astris club uses across its three-year cycle.

18 builds across a three-year cycle

Each build uses household materials; most go home.

YearBuildWhat it shows
APlanisphere star finderA rotating star map that shows which stars are up at any date and time
AMoon-phase and eclipse modelA working Sun–Earth–Moon model that recreates every phase and both kinds of eclipse
ADIY refracting telescopeA real two-lens telescope that shows craters on the Moon
APinhole solar projectorA box that projects a safe image of the Sun, sunspots included
ASundialA pocket sundial that tells time from the Sun’s shadow
AMoon crater experimentA tray of “Moon dust” that shows how craters and rays form
BScale Solar System walkA paper strip that turns the Solar System’s distances into a walk
BGravity-well orbit modelA stretched sheet that shows how gravity bends paths into orbits
BPins-and-string orbit tracerTwo pins and a loop of string that draw a true planetary orbit
BMars lander drop challengeDesign a lander that keeps its “astronaut” safe from a two-storey drop
BWater rocketA soda-bottle rocket that flies 30 metres or more on water and air
BPaper Mangalyaan modelA fold-up model of India’s Mars Orbiter, with every part labelled
CConstellation viewerA tube that projects constellations onto a wall or ceiling
CCD spectroscopeAn old CD and a cereal box that split light into a rainbow spectrum
CParallax rangefinderA card sight that measures distance the way astronomers measure stars
CStar life-cycle wheelA two-layer wheel that follows a star from birth to its end
CExpanding-universe balloonA balloon covered in “galaxies” that shows the Universe stretching
CExoplanet transit detectorA lamp, a ball and a phone light-meter that find a “planet” the way NASA does

Activities that need no telescope

  • A month-long Moon diary

    Sketch the Moon at the same time each night and predict the next shape. The best first habit an observer can build.

  • A year-long sunspot log

    Through a certified filter or a projector, count and sketch sunspots each month and watch the Sun rotate.

  • Science or fiction?

    Watch a space film, then argue which scenes physics allows. A favourite with older members.

  • Scale walks

    Pace out the Solar System on the school ground; the distances surprise everyone.

Common questions

What are good astronomy activities for primary students?
Hands-on, observable ones: acting out Moon phases with a lamp and a ball, a Moon diary, a planisphere, a sundial and a crater tray. Grades 4–6 learn best by noticing and describing.
What astronomy projects suit senior students?
Measurement projects: finding the Moon’s distance with Kepler’s third law, measuring the Sun’s rotation from sunspots, or splitting starlight with a spectroscope. These can grow into IB Internal Assessments, Extended Essays or olympiad preparation.
