Words and meanings to learn
MRSA (Methicillin-resistant Staphylococcus aureus)
a bacterial strain that has evolved resistance to many antibiotics and is particularly dangerous in hospital settings
mutation
a random change in the base sequence of DNA, which can occasionally produce antibiotic resistance in a bacterial cell
antibiotic
a medicine that kills bacteria or inhibits their growth, used to treat bacterial infections
antibiotic resistance
the ability of a bacterial strain to survive exposure to an antibiotic that would normally kill it
natural selection
the process by which resistant bacteria survive antibiotic treatment, reproduce, and pass resistance on to their offspring, causing the resistant strain to become more common over time
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.
