The science
of tree rings is known as dendrochronology. By studying cut sections
of tree trunks you can determine the age of the tree, how fast it
grew and what the climatic conditions were like during this time.
Here is a complete teaching package that can be used with pupils,
to study a forested area in North Staffordshire where the trees
were cut down. It is suitable for pupils at key stages 2 and 3.
There are photos of many tree sections, accompanied by teachers’
notes, pupil worksheets and cross–curricular exercises (science,
maths, history, geography and art) as well as an index of websites
on the subject. This is all explained in the powerpoint presentation,
which can be downloaded from the link below
