Hi Barbara,
what age would you do this with? Life cycle of a star was in the curriculum when I taught second level in the UK, but not anywhere in the Irish curriculum.
If you have children who are interested in this, you can engage everyone in the class by asking if they have noticed that stars at night are slightly different colours – in particular if you look at Orion, the top left star is slightly reddish tinged, and the bottom right star is a brighter blue-white. This has to do with the type of star they are.
Orion is visible in the early evening in January-February, so easy to see as soon as it gets dark. It disappears into the sunset in May.
