English National Curriculum - Science Science
Mission Objectives
Use results of an experiment to confirm the reactivity series
Use the reactivity series to predict displacement reactions
Write word and chemical equations for displacement reactions
Words and meanings to learn
displacement reaction
a chemical reaction in which a more reactive element displaces a less reactive element from its compound; both metals and non-metals take part in displacement reactions
displacement rule
a more reactive element will displace a less reactive element during a chemical reaction
reactivity
reactivity is the tendency of a substance to undergo chemical reaction, either by itself or with other materials, and to release energy
reactivity series
a progression of metals arranged by their reactivity from highest to lowest
vigour
substantial effective energy or force
Shannon started her journey with Developing Experts by completing PHD placement while studying for her Doctorate in Developmental Biology at the University of East Anglia. Shannon has since joined the team full-time as a Project Manager working with the company's industry partners. Shannon knows a lot about chickens!
Alison is a qualified secondary chemistry teacher and former scientist, seamlessly blending her background in scientific development with a passion for education. With over 15 years of teaching experience across state and independent schools, including most recently at Stafford Grammar School, Alison specialises in equipping students with the tools to excel in Chemistry at KS3, GCSE and A-levels. Her transition to online education, backed by a Master’s degree, has spurred her transition to freelance content creation and chemistry tutoring, tapping into a wealth of examining experience spanning over ten years to steer students towards their desired academic and professional paths.
When she's not shaping young minds, Alison unwinds by exploring the natural beauty of the Shropshire hills and embracing the tranquillity of Tai Chi, mirroring the balance she instils in her educational endeavours.
