Ken Walker

This website is dedicated to Ken Walker who was my first head of science back in 1971 who set me on a journey writing educational materials by asking me to make a booklet for 250 children visiting a zoo. He often reminded me of this but more importantly he was my mentor back in those days, letting me set up brand new science laboratories and run field courses at the schools outdoor pursuits centre and his advice stayed with me as I progressed in my teaching career and into my writing career too. Thanks Ken.
