Botany Science Fair Project

Soil Types and Water Retention

Medium
Soil Types and Water Retention | Science Fair Projects | STEM Projects
In this experiment, you will compare the water retention properties of sand, clay and silt soil. You will measure the amount of water retained in each soil type and observe which one holds the most water.

Hypothesis

The hypothesis is that silt soil will retain the most water.

Method & Materials

You will place sand, clay and silt soil in three separate pots, and measure the amount of water retained in each pot.
You will need three plastic pots, three plastic containers, three sheets of fine wire mesh, 600 ml of water, one sack of sand, one sack of clay, one sack of silt soil, one weighing machine, one measurement cylinder, and one marker pen.

Results

It was observed that pot C with the silt had retained the most water. It had the least amount of water in the collection container and the biggest increase in soil weight.

Why do this project?

This science project is interesting because it allows students to observe the differences in water retention between different types of soil.

Also Consider

Experiment variations could include repeating the experiment using mixtures of different soils, or using different amounts of water and soils from different locations to compare the results.
