What can we learn about minerals by observing them carefully?
3. Share the data
Complete the class table that you prepared before class. Make sure you have consensus about the properties from all the students who observed that sample.
- Who investigated [hematite]? What are the five properties you observed? Do you all agree?
If there are disagreements, determine how you will settle them. Should they observe the mineral again? Should a third party decide?
Continue recording the data and talking about it until the entire table is filled in.
