About This IB MYP Science Workbook
Science becomes much easier when students move beyond memorising definitions and begin to understand why things happen, how concepts connect, and how scientific knowledge can be applied to unfamiliar situations.
The workbook takes students from knowledge to application and evaluation, ensuring they master all three Criterion A strands: explaining scientific knowledge, applying equations to solve problems in familiar and unfamiliar contexts, and analyzing and evaluating information.
With clear revision notes, fully worked calculation examples, common mistakes to avoid, and two complete 30-mark exam papers, students gain the confidence needed for top grades.
