Finola,
see also the activity from Project Astro on Constellation Detectives (https://astrosociety.org/file_download/inline/808cd9d5-3a2e-4880-88d0-c29a6ecb60d5).
We have these printed A3 size, laminated, and tape them to the undersides of desks for children to lie on their backs and look up at the ‘stars’.
Some “simple star constellation template sheets” can be found at Mayo Dark Skies as https://www.mayodarkskypark.ie/wp-content/uploads/2023/11/MDSP-Constellations-v1.pdf
or you could use the Stellarium software (described in Module 4) to show constellation outlines and artwork on the IWB.
