    This article explores light pollution and practical ways to minimise it. Readers are introduced to key science ideas including the Bortle scale (a way to measure the brightness of the night sky for a particular location), animal migration and astronomy (galaxies, nebulae and star clusters).

    New Zealand has the largest dark sky reserve in the world – Aoraki Mackenzie International Dark Sky Reserve – with a second reserve planned in south Wairarapa. These reserves are valued by professional astronomers, tourists and New Zealanders who want to stargaze for research and for fun.

    The article also makes connections with tātai arorangi (Māori astronomical knowledge) – with information about Tautoru (also recognised as Te Hau o Rua) and Matariki.

    Connected author and teacher Matt Boucher used the online citizen science project Planet Hunters and Agent Exoplanet within a year 7/8 unit on light. Read the case study and accompanying unit plan, with activities, to find out how he modelled the transit of an exoplanet and the impact of this on the star’s light intensity.

    Teacher Melissa Coton used the online citizen science project Globe at Night with her year 5/6 class as a way of highlighting a real application for the learning they had been doing about light and its properties. Read the case study and accompanying unit plan, with activities, to find out how she transitioned from learning about light to considering light pollution and its impacts.

    Loss of the Night is an international citizen science project that aims to quantify the illumination of the night sky caused by artificial light.

    Discover more about tātai arorangi in the article Revitalising Māori astronomy. This article also includes a video and links to star lore and navigation.

    Tātai arorangi also features in the recorded PLD webinar Mātauranga Māori.
