This is a homemade 'scratch art' type of lesson using oil pastels layered in contrasting colours,
then scratched with a wooden bamboo stick.
I found THIS photo pinned on Pinterest but couldn't find the original source. Please tell me in the comments section if you know the originator of this project.
Grade 3 students started off by drawing an owl onto smooth cardstock,
then outlined it using a thick Sharpie.
On scrap paper, they practiced using the oil pastels and decided on
some contrasting colours to use.
Colour in one area really thickly with one colour, then add another thick layer of a contrasting colour right on top. Using a bamboo stick/skewer, students scratched out various types of patterns.
Afterwards, we cut these out.You could also paint the background.
