From Rocks to Soil

Categories:  Chemistry ,  Science ,  Soils

In this lesson students explore weatherization (physical and chemical) by doing a series of short experiments that demonstrate how rocks and minerals are broken down into soil. Expand this lesson further by taking students on a field trip to look for rocks breaking down into soil.


Option 1

  • Set up five experiment stations based on the activities below
  • Have students work in small groups, record their findings at each station, then complete the Weatherization worksheet.
  • Plan for about 10 minutes per station.
  • When everyone has done all the experiments, assign each group one of the activities to present and explain to the class.

Option 2

  • Break students into groups. Assign each group one of the activities below.
  • After completing the experiment once on their own, each group will then demonstrate their activity for the class and explain what is happening and how it relates to soils formation.
