A complete KS3 Science lesson on scientific variables and fair testing. Includes definitions of independent, dependent and control variables, scaffolded worksheets, and a practical paper helicopter investigation. Perfect for Working Scientifically skills lessons.

Students learn to define and identify independent, dependent and control variables through guided practice, real-world examples, and an engaging paper-helicopter investigation. There is also a graph skills opportunity following on from the practical investigation.

Extra equipment needed for practical investigation:
