We made plastic bag aquariums! This is such an incredibly easy project and FUN too! All you need is a plastic bag with a zipper top, permanent markers, and some hair gel. There is something satisfying about squooshing your fingers across the gel!
Preschool Art project: Draw fishes beforehand on paper, students paint and decorate with sequins. While that is drying, students can paint a background of the ocean. Maybe glue on yarn for seaweed along the bottom?
