The Geography Research Department of the University of Durham (Durham Geography) have developed three worksheets for teachers that provide guidance notes along with example demonstrations and classroom practicals of:

*The drivers of sea level change: isostasy, eustasy and relative sea-level change.

*Salt marshes and sea level: salt marsh succession and its relationship to sea level.

*Microfossils as indicators of past sea level: how salt marshes and the microsfossils preserved within them act as 'geological tide gauges'.

The material is designed to tell a story: from the big picture of the causes of sea-level change, down to the tiny plants and animals that tell scientists how sea level has changed in the past. However, particular elements can also be used on their own. The ideas covered have been designed with Key Stage Four in mind, but can be adapted to any age group.


Climate Change and Glaciers

This collection of resources consists of a set of lessons through which Key Stage Three students investigate the impacts of climate change on glaciers. The learning objectives are: *To understand the definition of a glacier *To understand what glacier mass balance means (what inputs mass and what are the outputs) *...

Worksheet 1: Drivers of Sea Level Change

This resource looks at the two main drivers of sea level change - isostasy and eustasy. Each of these terms is explained and a worksheet covers both ideas in three practical demonstrations.

In the first practical, which includes both isostasy and eustasy, students undertake experiments which prove that...

Worksheet 2: Sea Level and Salt Marshes

This resource explains what a salt marsh is and how they record sea-level changes. As salt marshes are zoned by tidal inundation, salt marsh plants and sediments can then record changes in sea level as the zones move horizontally in response to vertical changes in sea level.

In a practical experiment,...

Worksheet 3: Microscopic Sea Level Recorders

This resource considers what the microscopic plants and animals found over a salt marsh can show about past sea levels. The two activities in this resource explore these microscopic sea level recorders and how researchers use them to understand sea-level change.

In the first activity, students explore the...
