“Snooping into our soils” –The IYS2015 for National Science Week in the Wimmera

Children explore samples with soil samples brought from home.

They conduct physical and chemical tests, to see what happens to their soil sample when they:

add water – a drop, a blob, a layer

make a ‘soil shake’

mix with pH indicator solution.  

They discover soils which:

do/not soak up water

do/not climb on top of water droplets and blobs

do/not bubble in water

make different layers when mixed with water and air (sand, silt, clay floating, plant bits floating)

This is Session 3 of a 4-session program funded in schools by the Wimmera Catchment Management Authority, and created for the schools by Jeanie Clark , enviroed4all® , Warracknabeal.
