Hi Fiona,
If your classroom faces the right direction you can draw the children’s attention to the Sun shining in the window at any time of year! I often ask children when I take the StarDome out to a school which way their classroom faces. I get a lot of blank stares, so I ask – what time of day does teacher have to close the blinds on a sunny day?
If in the morning – your classroom faces east.
If in the middle of the day – your classroom faces south.
If in the afternoon – your classroom faces west.
You could even ask children if their kitchen faces east – do they get the sun in the morning when they have breakfast? Survey the class and see how many have this.
