STEM videos
Welcome to our virtual STEM learning programme.
These short videos explain how we are using computing, science, maths and engineering to help people to communicate and stay connected.
We hope these will help to bring the school curriculum to life and give you a view of what you are learning at school or college is used in the world of work.
Why not start with taking a look at our Purposeful Innovation video to find out a little bit more about what we do?
