Name those minerals!
Your team of geologists has studied a set of unknown minerals. You've figured out the hardness, the streak colors, the luster and whether or not the minerals have cleavage. You have also been able to generate some additional properties, including whether or not the minerals are magnetic. Once you have compared your findings to a mineral identification chart, you should be ready to identify your minerals.
On this post, your team needs to decide what the minerals are and provide your reasons for believing those identifications. Collaborate with your team, create a brief Word document, check for good spelling and clear ideas, and then post it here. In the names section, each student of your team should have his or her name included.
A sample might look like the following:
We believe that mineral number 1 is quartz. The color of the mineral, the hardness and the streak color from our sample matches the mineral identification chart for quartz. Quartz does not have cleavage and has a non-metallic luster. That matches the sample and the mineral identification chart information.
You would then make a new "mini-paragraph" for each of the other three minerals. The above is just a sample, and your team can design the information how you see fit. However, you need to provide as much evidence as you can about why you think the mineral is what you have decided it to be.
Once everyone has posted their results, we will examine the findings and see who was correct. Think hard, communicate and collaborate with your team and create a good post of your findings.
