Today we were looking at the different properties of 3 soil types- clay, sand, and loam and how each type responds to water.
We looked at the textures of salt (sand) flour (loam) and modelling clay (clay)
Here are our observations
Soil type
example
|
dry
|
wet
|
Salt (sand
granules)
|
Gritty,
rough, scratchy
|
Sticks together,
a bit sticky
|
Flour (Loamy
soil)
|
Smooth,
soft, fine
|
Gluey,
lumpy,
|
Modelling
Clay (Clay)
|
Stretchy,
firm,
|
Sticky,
runny
|
The different types of soil react to rain etc. differently, causing constant changes in the Earth's surface
