Earth Science – Soil Lesson Plan Yr 4


Summary of lesson plan:

This activity is directly linked to Year 4 Earth Sciences. Students will be investigating the components of soil and they will understand the importance soil has on our everyday lives.

Australian Curriculum Links:

  • Year 4: Earth’s surface changes over time as a result of natural processes and human activity. ACSSU075.
  • Year 4: Safely use appropriate materials, tools and equipment to make and record observations, using formal measurements and digital technologies as appropriate. ACSIS066.
  • Year 4: Represent and communicate ideas and findings in a variety of ways such as diagrams, physical representations and simple reports. ACSIS071.

Lesson Plan Sequence:


  • Start a discussion: Is soil an important ingredient in your everyday life?


  • Discuss with your children that last night you slept on a building built on soil. You breathe air from plants that come from the soil. You wear clothes made from plants that grow in the soil. We build on soil. We play on soil. We drive on soil. The entire Earth is dependent on soil.
  • Ask your students what they think soil actually is.
  • Allow students to discuss with a partner what they think is in soil.
  • Explain that soil is made up of rock, sand, clay, silt, air, water and organic matter (dead plants and animals).
  • Show the images of soil and have students identify what they can see.
  • Explain to your students that today they will pretend to be a Geologist.
  • Ask “What is a Geologist?”
  • Draw out that it is someone who studies things on the Earth.
  • Provide students with 2 different samples of soil. You can use beach soil and garden soil.
  • Set students to task on the Geologist Soil Discovery Activity Sheet.

Other Activity Ideas:

  • View website:
  • Create a picture by gluing down sand/soil.
  • Act out things that grow in the soil.
  • Write a recipe for soil.
  • Write a story about the day in the life of a soil, grain of sand etc…
  • Make edible soil.


  • Worksheets marked and collected to see if students can identify and label the components of soil.
  • Students can complete an exit slip explaining what they have learnt about soil.
