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.
