Dot Boughton (Lancashire & Cumbria FLO) was invited by Lancaster Girls’ Grammar School to organise archaeological activities for the students (aged 11–14) as part of their ‘Science Week’. Under Dot’s supervision the girls examined a large amount of archaeological finds from Stone Age to the modern period, which they sorted according to what they were made from, e.g. glass, plastic, metal, stone, etc. Then, they were asked to analyse the finds further, such as by metal type and treatments applied to pottery. After, they discussed the properties of the materials, and why some artefacts were made some types, but not others. For the final exercise the students had to organise the finds into a timeline, to demonstrate how the use of different materials changed over time.
