Y3 Testing for Rock Permeability – The Water Drop Test

Pupils learn that some rocks are permeable (they allow water to pass into and through them) and some are impermeable (they do not allow water to pass into or through them). They carry out the 'Water drop test' to investigate which of the rocks they are investigating are permeable or impermeable.



Learning Objectives:

  • PoS - compare and group together different kinds of rocks on the basis of their appearance and simple physical properties
  • NaG - pupils should explore different kinds of rocks and soils, including those in the local environment
  • WS - pupils should ask relevant questions and use different types of scientific enquiries to answer them; set up simple practical enquiries, comparative and fair tests; make systematic and careful observations and, where appropriate, take accurate measurements using standard units
