Fieldwork: Planning a soil enquiry and collecting data

I can collect soil texture data on my school site.

These resources will be removed by end of Summer Term 2025.

Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.

Lesson details

Key learning points

  1. Soil texture can potentially affect the rate of water infiltration.
  2. A fieldwork enquiry can be used to find the extent to which soil texture effects infiltration.
  3. Geographers can use a combination of data collection techniques to investigate the characteristics of soil.

Keywords

  • Soil texture - characteristics of soil, such as how large the soil particles are, or how large the pores (spaces) between the particles are

  • Porosity - how porous soil structure is (i.e. the size and quantity of spaces between soil particles)

  • Infiltration - the movement of water from the surface to the lower soil layers

Common misconception

Large soil particles means there are smaller pores between them.

Soil that is made-up of small particles has a structure where the particles can fit together more easily reducing the pore size between them.

Introduce students to the fieldwork equipment they are going to be using beforehand in the classroom. This will help them to remember the names of equipment and increase their confidence in handling it.
Teacher tip

Equipment

Infiltrometer; 500ml water container; soil auger; clear sided (ideally glass) 100ml measuring cylinder; rubber mallet; stopwatch; clipboard
