What kind of rock is that? A Science (Geology) lesson for Year 8


Summary of Lesson Plan:

This lesson provides students with the opportunity to develop an understanding of the different kinds of rocks and how they are formed through a real world-learning context. This lesson was designed for a year 8 class; it has been tested and worked well with high student engagement.

Year 8 Science Understanding:

  • Sedimentary, igneous and metamorphic rocks contain minerals and are formed by processes that occur within Earth over a variety of timescales (ACSSU153)
  • AC Elaborations:
    • representing the stages in the formation of igneous, metamorphic and sedimentary rocks, including indications of timescales involved.
    • identifying a range of common rock types using a key based on observable physical and chemical properties.
    • recognising that rocks are a collection of different minerals.
    • considering the role of forces and energy in the formation of different types of rocks and minerals.
    • recognising that some rocks and minerals, such as ores, provide valuable resources.


Lesson Plan Sequence:

*** Please note that this lesson sequence is supported through the use of a Powerpoint presentation ***

  1. Show the students the power point provided below.
  2. Students then complete the worksheet.
  3. As a class, discuss the answers.
  4. Have the students create an informative poster on one of the rocks with facts and pictures. (they will need to research facts)
  5. Present the posters to the class.


  • Check student understanding about what they have learned about how sedimentary, igneous and metamorphic rocks are formed over time.

Assessment Ideas:

  • Anecdotal notes on students
  • Collect worksheets to check understanding.
  • Use posters as summative assessment.
  • Students record their findings using a digital device and share with class.
