I found this lesson via Flickr on Pinterest, but don't know to whom I have to give credit...

Draw a horizon line a little below the middle of a black sheet. Use different colours chalk pastels to colour the sea. Do not use too much chalk, so that it can be smudged.
Cut a strip of mountains out of black paper. Paste it on the horizon line. Use white chalk pastel to make snow on the mountains. Draw the northern light above the mountains. Smudge colours.

Paint the space between the leaves with water colour paint. Leave a white edge around the leaves. Let dry. Paste the artwork on a coloured sheet and finish the half leaves with a white pencil on this frame.
I did this lesson in October 2009, and soon saw it on many blogs. It's still one of my favorite lessons.
This week we had the Dutch Week of School Breakfast, a good reason to build a lot of new burgers with students of grade 4.
