KS3 Science: Working Scientifically — Challenge

KS3 Science: Working Scientifically — Challenge is a greater-depth stretch activity book for Key Stage 3 scientific enquiry, mapped to the DfE National Curriculum. Five demanding challenges push confident learners through isolating the independent, dependent and control variables in a rate-of-reaction investigation, distinguishing accuracy, precision, resolution and reliability, reading finer scales and calculating a mean while ignoring an anomaly, handling trickier conversions, and interpreting graphs, axes, correlation and conclusions. Challenges 1–4 hold around twenty-two auto-marked questions; Challenge 5 is an open evaluation and reasoning task — judging a flawed method, handling an anomaly and justifying a conclusion from the data — with a full worked answer key. Includes teacher, parent and pupil notes and is fully SEND-friendly with high-contrast and large-text modes.
