...is adorned with blossoms!
We used coffee filters that I cut into somewhat floral shapes, and the kids coloured with water-based markers. Then I sprayed them with water so the colour bled and stuck them to the windows to dry (we get a lot of sun, and, they looked pretty there!
Now my students point out blossoms constantly. I love using art to teach because I've noticed that when people make an artistic rendering of something, all of a sudden that thing becomes theirs. They become so intimate with it.
