Scientific Method Reading & Worksheets | KS2/KS3 Science

Teach the scientific method and Working Scientifically skills with this illustrated nonfiction reading comprehension resource and 15 printable worksheet activities. Designed for upper KS2 and lower KS3 (Years 6–8), this ready-to-use pack combines science literacy, experimental reasoning, vocabulary development and practical enquiry skills.

Using a familiar investigation into how water temperature affects sugar dissolving, pupils explore observations, hypotheses, predictions, independent and dependent variables, controlled variables, fair testing, data collection, repeated trials and scientific conclusions.

Pupils progress from understanding scientific concepts to interpreting experimental data, calculating averages, plotting graphs, identifying unfair tests and evaluating evidence. A second investigation involving paper towel absorption encourages pupils to apply their understanding in a new context.
