Graham Bray Heathfield, United Kingdom I have 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 products.
Physics 1 - Length and time
In this video I show how to: - Use and describe the use of rules and measuring cylinders to find a length or a volume - Use and describe the use of clocks and devices, both analogue and digital, for measuring an interval of time - Obtain an average value for a small distance and for a short interval of time by measuring multiples (including the period of a pendulum). - Understand that a micrometer screw gauge is used to measure very small distances
