Words and meanings to learn
waste water
used water that goes down the drain, including sewage, agricultural runoff and industrial waste
aeration
the process of pumping air (oxygen) into the water during secondary treatment to encourage aerobic microorganisms to grow and biologically break down the dissolved organic pollutants
sludge
the concentrated solid waste (containing grit and organic matter) that settles out of the wastewater during sedimentation, which is then collected and treated separately
sedimentation
the primary treatment stage where gravity is used to make heavier, insoluble solids (like grit and tiny food scraps) sink to the bottom of a tank, forming sludge
chlorination
final treatment stage where a sterilising agent (like chlorine or UV light) is added to the water to kill any remaining harmful microorganisms (pathogens) before the water is discharged
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.
