This print and digital coursebook has been developed from extensive research through lesson observations, interviews and work with our research community (the Cambridge Panel) to meet your specific needs. Activities and questions develop your essential science skills, with a focus on practical work. Exam-style questions give you valuable practice. Projects provide opportunities for assessment for learning, cross-curricular learning and developing skills for life. There are multiple opportunities to engage in active learning, such as scripting a podcast, to discussions and debates. Activities build in complexity to support your learning, and worked examples help you whenever you need to use an equation.
