Begin the lesson with an engaging question: 'Have you ever wondered how rocks are formed and transformed over millions of years?' This will pique students' curiosity about the rock cycle.

The Rock Cycle
Learning Objectives
- Identify and classify the three main types of rocks: igneous, sedimentary, and metamorphic.
- Explain the processes that lead to the formation of igneous, sedimentary, and metamorphic rocks.
- Describe how the rock cycle involves the transformation and recycling of rock material over geological time.
- Understand the role of heat, pressure, and erosion in the rock cycle.
Introduction and Hook
Introduce the topic with a brief overview of the three main types of rocks: igneous, sedimentary, and metamorphic, and their formation processes.
Direct Instruction
Explain the processes that lead to the formation of each rock type using diagrams and examples.
Use the video 'The Earth's Geosphere' to illustrate how the geosphere interacts with other Earth systems and the role of rocks within these interactions.
Guided Exploration
Facilitate a discussion on how heat, pressure, and erosion contribute to the rock cycle. Use real-world examples to make the concepts relatable.
Encourage students to identify different rock types in their local environment and hypothesize about their formation.
Hands-On Activity
Conduct a hands-on activity where students model the rock cycle using materials like crayon shavings to simulate weathering and heat.
Use the 'Modeling the Rock Cycle' assessment to guide students through the experiment and assess their understanding of geological processes.
Independent Practice
Assign students to research and create a presentation on a specific type of rock, detailing its characteristics and formation process.
Encourage students to find and bring in samples of rocks they find interesting, and classify them based on their research.
Check for Understanding
Use a quick quiz or exit ticket to assess students' understanding of the rock cycle and the processes involved in rock formation.
Try the QuizReview and Reflection
Have students reflect on what they learned about the rock cycle and how it connects to other Earth systems.
Encourage students to share their thoughts on how understanding the rock cycle can help us appreciate Earth's dynamic systems.
Assessment and Extension
Provide students with the 'Earth’s Spheres' assessment to evaluate their understanding of how the rock cycle interacts with other Earth systems.
For further exploration, students can engage in a 'Biome Research Project' to understand how different environments influence rock formation and transformation.
