Soil permeability: plan (non-statutory)
I can plan an investigation to compare how water moves through different soils.
Soil permeability: plan (non-statutory)
I can plan an investigation to compare how water moves through different soils.
These resources will be removed by end of Summer Term 2025.
Lesson details
Key learning points
- Soil scientists ask questions about which type of soil is best for different purposes.
- Water moves very easily through permeable soils and very slowly through soils with low permeability.
- In a comparative test investigation, variables must be controlled so that only one thing is changed.
- Scientists make plans that include what they will do and what equipment they will need.
Keywords
Permeable - If a material or substance is permeable it will allow liquids and gases to pass through it.
Plan - A plan is a method that maps out the steps that will be taken during an investigation.
Comparative test - In a comparative test, the thing that is being changed has labels, such as the types of materials.
Variable - A variable is something that can be changed, measured or kept the same in an investigation.
Common misconception
All soils are the same when it comes to permeability, how wet/dry a soil is depends how much it rains.
By planning a practical activity, pupils will be able to measure and observe how permeable different types of soils are.
Equipment
Plastic bottle, soil samples, funnel, filter paper, measuring jug and timer or stopwatch may be helpful at this planning stage but not essential.
