Welcome to the Tunnelworks Maths AS Area

Introducing the Thames Tideway Tunnel. Watch the video to find out why we need to clean up the River Thames.

Here you'll find one lesson, complete with an online presentation, student worksheets and detailed lesson plans. The lesson challenges students to solve a realistic engineering problem to help design, build or operate the Thames Tideway Tunnel. 

After that, you can ‘dig deeper’ with follow-up ideas for more able students. 

Finally, a CREST gold project is outlined, if you wish to connect your work to this well regarded science award scheme. 


In this lesson students practice generating and transforming trigonometric graphs, including translations and stretches. Using information about tidal patterns in the River Thames, students develop a simplified chart for tides at London Bridge. 

CREST Gold Award 

Research project: students research the science that helps us understand why the number of sewage discharges into the River Thames has increased over time and the effect these have on river wildlife and the environment. They will discover what people think about the River Thames and create a communications activity to explain the science behind the project.
