Trial by Ordeal.
To find out if someone was guilty they would be asked to hold a red hot piece of metal. It would be bandaged up and left for several days. If the wound healed they were innocent, if the wound became infected they were guilty.
The Pillory (stocks)
People would be put in these and displayed in the street for people to throw rotten food at. This was done to shame them and it was so everyone knew what type of a person they were.
Trial by hot water.
The children then looked at the Anglo-Saxon crimes and punishments and reenacted them.
