Grade 8 and 9 NS/LS Skills Booklet

This Investigation Skills Worksheet for Natural Science & Life Science equips learners with the practical scientific skills needed across both subjects. It covers how to formulate an aim, hypothesis, and identify variables, how to construct and interpret line, bar, histogram, and pie graphs, and how to present data using tables and biological diagrams. It also builds confidence with common NS & LS calculations, and explains the concepts of validity and reliability in scientific investigations — an essential companion resource for practical and research-based assessments.
