2 Lark made some really interesting projects about the Age Of Exploration. They made a model of a quadrant and made a real book to accompany the model.
They also made a captain’s log. They used a used teabag to make the paper look old.
They also made a Caravel which must have taken them ages to make. It was really accurate, containing lateen sails for navigation around shallow waters and square sails for speed on the high sea.
One made a log and line which measures how deep the water is and another team made an astrolabe. This device helped sailors measure how far north or south they were.
