Purpose:
To determine the porosity of soil samples and relate porosity to soil vulnerability to compaction.
Summary:
Students will take at least two different soil types and determine which soil type will hold the most water - have the greatest porosity. Students will be able to determine which soil then has the greatest porosity and draw conclusions about the type of soil that is more easily and likely to become compacted (the soil with the least porosity).
