Dating ceramics using rehydroxylation

This resource looks at the recently developed technique of rehydroxylation for dating ceramic objects using an exponential growth model. The resource allows students the opportunity to apply their knowledge of growth and decay, along with logarithms, to genuine scientific process.

Strand

Algebra and graphs

+
Prior knowledge

Rules of logarithms, exponential functions.

+
Relevance to Core Maths qualifications

  • AQA
  • C&G
  • Eduqas
  • Pearson/ Edexcel
  • OCR

+
Suggested approaches

The task is suitable for individual or paired work, and could be used as a model case study exam-style question.

+
Relevant digital technologies

This would be very appropriate for using a spreadsheet in order to both calculate and graph the natural log values.

+
Possible extensions

Students could look at how the method of hydroxylation compares with that of Carbon 14 dating that was described in the article which is used for dating objects of an organic source.
