Pupils were invited to Pool Academy to learn what life is like for archaeologists.
The children were encouraged to get down in the dirt and dig for treasure as part of the fun history lesson.
Bits of pottery, coins and other artefacts had been buried in a section of the school grounds ready to be unearthed, washed and catalogued.
History Leaders from Pool Academy were on hand to help the youngsters in their quest to find as many pieces of history as they could find.
Mr Turner, History teacher at the academy, said it was a great opportunity for children to learn independence and meet their future teachers if they choose to come to the school.
He said: “The pupils were learning what it is like to be an archaeologist. They were allocated history leaders from Pool Academy.
“The pupils have to find the artefacts, clean them, catalogue them, record and bag them.
“The event gives history leaders independence teaching the children what to do and facilitate the instructions.”
Mrs Wyatt, from Treloweth Primary School, said: “The event was amazing. The children showed independence and great collecting and were really excited by the artefacts they were fading.
The big dig linked well with our roman topic.
“It was a fantastic event.”
Mr Turner said the event had been organised for primary schools in the area.
