The camera is made from old material like leather.
The teapot is made from paperclips/wire,tape,and I think some paint.
The dragon is made from clay and most likely reusable sculpting tools.
The wolf or dog looking animal is a origami project.
The colorful book type thing is made from old construction paper or maybe an old book.
I would most likely use the materials they used to make the teapot because its a really easy process to bend paperclips the way you want to and then cover them in tape and color them with pain,crayons,markers,etc... Plus once you're done you have a 2D or even 3D beautiful project that you can show off.
