'Why are some crystals extremely rare and valuable? - Teacher notes' is a resource from 'Why are some crystals extremely rare and valuable?', a Year 3 Science lesson from the unit Rocks and soil. This lesson uses an enquiry-approach method, and will facilitate students answering the question 'Why are some crystals extremely rare and valuable?'

<p>Understanding the rarity and value of crystals begins with recognising that minerals possess various qualities, one of the most significant being hardness. Teachers guide pupils to explore the Mohs hardness scale, a longstanding method for classifying minerals by their resistance to being scratched. This scale is instrumental in explaining why certain crystals, such as diamonds, are considered extremely valuable. Diamonds, being the hardest known mineral, command a high value due to their exceptional hardness and the qualities that arise from it.</p>

<p>In an interactive classroom setting, pupils are encouraged to work in small groups, delving into the characteristics of individual minerals. Each pupil examines one mineral in detail and subsequently shares their findings with their peers. Through this exercise, they gain a comprehensive understanding of the main types of rocks found on Earth and the factors that contribute to the rarity and value of some crystals. The collaborative nature of the task not only enhances their knowledge of geology but also fosters communication and teamwork skills.</p>
