How does electricity flow through small objects?

Researchers at the University of Oxford are investigating what happens to electricity as it flows through tiny, molecular-scale objects. Understanding this will be the foundation for developing new, tiny electronic components for a range of devices. In these resources students will get to grips with SI units for very big and very small numbers (KS3), learn about graphene and other allotropes of carbon (KS4), are introduced to logic gates and truth tables (KS4), and write a news story about the recent discovery of gravitation waves (KS5)

KS3 - What is nanoscale?
KS4 - Carbon Copy
KS4 - Logically Speaking
KS5 - Wave Machine
In this lesson students explore some of the reasons why scientists use SI units and become more familiar with the SI units for very small objects, particularly nanometres.
. In this lesson students find out more about the allotropes and, in particular, the allotropes of carbon by building models.
In this activity students learn about the development of electronic components through history and learn about logic gates from their diagrams and truth tables.
In this lesson students look at some of the other uses of interference (of light waves) and prepare a ‘news item’ about the recent discovery of gravitational waves.
