341Hi, I’m Graham Bray and welcome to my Online Science Teaching Blog.

I’ve been a teacher for over 25 years, and am currently the Director of STEM (Science, Technology, Engineering and Maths) at a large comprehensive school in East Sussex. To bore you with the qualifications, I have a Joint Honours Degree in Botany and Zoology, and a PhD in Biological Sciences.  I was also one of the first Advanced Skills Teachers in Kent.

I am a passionate believer in life-long learning, and I will do whatever I can to encourage learning for all ages.  Using videos to enhance learning has great potential, and I hope to exploit this potential via my website.

On a personal level I am married to Wendy, a primary school headteacher, and we have two grown up daughters, Fran and Fern. We also have a little dog called Maisie-Rae! When not creating videos or teaching I relax (!) by working out at the gym, watching rugby and football, and doing a little work around the garden. I am also an avid fan of Grand Designs and The Apprentice.
