Rom and Romola explain that the baths were used as a place to swim and pray to the goddess Minerva, who the Romans believed had healing qualities. The clip shows the remains of the caldarium, a very hot bath, the tepidarium, a warm bath, and the frigidarium, a freezing cold bath. It also explains how the Romans used a hypocaust, an underground heating system, to ensure they always had hot water.

Pupils could use plastic construction bricks to build a model of a Roman bath house, using information from the clip and supplementing it with images from books and webpages. The children should label the caldarium, tepidarium and frigidarium (hot, warm and cold baths). Encourage pupils to equip their model with a hypocaust too, placing a floor over stacks of plastic bricks to create a cavity. The hotter the bath, the larger the hot-air cavity beneath its floor.
