Cress Heads

Cress is a plant with small green leaves that is used in salads or to as a food garnish. When grown in a small pot or container, the cress resembles ‘green hair’ which is where the idea of ‘cress heads’ originates. In this lesson, students will be learning about cress and cress heads before designing their own cress head model suitable for 3D printing.
