    This unit plan shows how teacher Melissa Coton extended her year 5/6 students’ learning about light by engaging them in learning about light pollution at night.

    Students first learned about light: light waves travel in straight lines, shadows, colours in the visible spectrum and how light waves behave – reflection, refraction and diffraction. They then extended their learning about light to explore light pollution and its impacts.

    To collect scientific data about light pollution in their area, students engaged with the online citizen science project Globe at Night. Although overcast skies meant they weren’t able to gather their own data, as planned, teacher Melissa did get some 3am photos that the students evaluated. They also compared the Globe at Night data with data collected from satellites. A core focus of this part of the unit was developing the science capability ‘Critique evidence’.
