Welcome to class! 

In today’s class, we will be talking about the properties of soil. Enjoy the class!

Physical properties of soil

Physical properties of soil classnotes.ng

Physical properties are properties that can easily be determined through visual inspection or feel. Each soil type has some physical properties. The property of any soil type is what makes it different from the others. Soil is made of varying amounts of silt, sand, and clay. The proportion of these components determines if the soil is a sand, loam or clay or any combination of these

Activities

Collect soil samples from three different locations

  1. From the beach
  2. From mud
  3. From the garden of farmland

Take a look at each sample, feel each sample between the fingers. And write down your observations.
