The document provides instructions for students to create a historically accurate model of a medieval castle no larger than 8cm tall, 15cm long, and 22cm deep using materials like cardboard, lollipop sticks, foam, or polystyrene. Key features to include are a drawbridge, moat, portcullis, arrow slits, and a keep. Students can add additional features and context, and have 6 weeks to complete the project by pacing themselves wisely.
