I adapted this project for my campers a couple years ago. Originally I subbed this lesson in a middle school. It was more connected to the idea of recycled art because you can paint endangered animals on the cans. Instead, because it was summer camp we used emojis to decorate the cans and the campers loved that idea.
The inspiration comes from an artist named Charles Kaufman
Have the kids flatten their cans by stepping on them carefully. You have to take care with the top and bottom and make sure it folds over the right way, so it isn’t just mindless stomping. Trace the can 4 times on a paper. They have to try 4 different designs before committing to one. When they picked an animal or emoji ask them to think about colors and backgrounds. If you’re doing the animals they can research what the animal eats. If you’re doing emojis you can do patterns and colors.
Prepare the can by paintings it with white tempura paint 1 or 2 coats, 2 is probably better. They can do this after they trace so it is dry and ready for next time but you can always use a blow dryer to make it dry faster but be careful because it can get super hot!
When they decide on a design they can use a pencil to draw it on the prepared white tempura. Depending on the age and skill of your painters you can have them paint the subject first and then the background surrounding it. Or you can have them do a base color for the background then the subject on top. I just like to do the animal/emoji first because they can draw it with pencil on their cans and see it better.
You can glue gun string to the back and have it hang or hot glue it to a matte board and it will loose nice and framed!
