Art meets history meets science, as kids visualize a medieval kingdom and its centerpiece: the castle. Lessons in scale model building start the session as students construct walls, moats and galleries. Students build their own simple machines: catapults for launching projectiles at the walls they've made, followed by the design of cranes and towers needed to rebuild their scale model fortress. Students visualize the kings, queens, knights, farmers and animals found inside and outside the walls and the faires, festivals and tournaments (with jousting matches!) that are the most fun in an imagined castle community.
