Aim: To determine how much water there
is in two soil samples.
Materials Used:
20ml of soil sample 120ml of soil sample 2
measuring cylinders
2 crucibles
Spatulas
lab scales
Newspapers
Permanent markers
Loamy soil is a better choice for growing plants than sand as loamy soil can hold more water. This is because loamy soil is made up of organic material while sand is just rocks. This is a good study as it shows which soil to use for growing plants with a certain amount of water needed as to not drown or thirst the plant of water.
The Loamy soil would have more water because it is made up of organic material whereas the sand soil has small broken down rock particles.

damp soil before heating | 2nd reading mass of crucible and soil
after heating | 3rd reading of mass and crucible and
soil after heating | Mass of water in the soil (difference
between the starting and end mass) |
