Words and meanings to learn
wasted energy
energy that is not usefully transferred and often spreads out into the surroundings, usually as heat or sound
energy dissipation
the spreading out of energy into the surroundings in a form that is less useful, often as thermal energy, making it difficult to use for further work
friction
a force that slows down moving objects when two surfaces rub against each other, causing energy to be wasted as heat
efficiency
a measure of how much input energy is usefully transferred by a device or process, given as a percentage
useful energy
the energy transferred in a way that helps achieve the device's intended purpose, like light from a bulb or motion from a motor
Samantha is an accomplished science educator whose current work centres on curriculum design and professional development, supporting teachers to deliver high-quality science education through evidence-informed approaches. She is a former Head of Chemistry and Sixth Form Tutor with extensive Key Stage 4 and 5 experience, and has worked as an AQA examiner, giving her valuable insight into assessment standards and what students need to succeed.
Samantha has written the complete KS4 Science curriculum, fully aligned with the AQA GCSE Science: Trilogy specification. Covering biology, chemistry and physics, the curriculum is carefully sequenced so that students build knowledge cumulatively and see clear connections between concepts across the three sciences. Drawing on her experience as an examiner and on research into effective teaching, she has designed it to embed retrieval practice, clear explanation, worked examples and the required practicals throughout, preparing students for the demands of the GCSE exams. Grounded in the realities of the classroom, the curriculum is rigorous for students and manageable for busy teachers.
In her spare time, Samantha enjoys playing the accordion with her local orchestra and has recently taken up cricket.
