Introduction and Hook
Direct Instruction
Introduce the concept of minerals, explaining that they are naturally occurring substances with specific chemical compositions. Discuss common minerals such as gold, silver, and diamond, and their unique properties.
Explain the composition of rocks, emphasizing that they are made up of one or more minerals. Discuss the different types of rocks and their formation processes.
Guided Exploration
Watch the video 'Using Rocks and Minerals' to explore the practical applications of these natural resources in construction, technology, and jewelry.
Engage students in a discussion about the different environments where rocks and minerals can be found, such as mountains, rivers, and coastlines.
Hands-On Activity
Conduct a classification activity where students sort various rock and mineral samples based on their properties such as color, texture, and hardness.
Use the 'Properties of Rocks' assessment to guide students in observing and recording the characteristics of different rock samples.
Independent Practice
Assign students to explore their surroundings and identify different rocks and minerals, noting their locations and possible uses.
Check for Understanding
Use formative assessment techniques such as questioning and peer discussions to gauge students' understanding of the differences between rocks and minerals.
Review and Reflection
Have students reflect on what they have learned about minerals and rocks, discussing their importance and applications in everyday life.
Assessment and Extension
Test students' comprehension with the 'Rocks Around Us' assessment, where they observe and describe rocks from different locations.
Encourage further exploration by assigning the 'How Rocks Form – Comprehension' assessment to deepen understanding of the rock cycle.
