Group Activity

​

​

​

You will be assigned to a breakout room; work together with your group to answer questions listed under your group name/number on the next slide.

​

​

You may use the Internet for research, but make sure your answers are in your own words!

​

​

Choose a recorder/spokesperson who will record your answers and share what your group came up with when we come back together (or you can assign different people to share your answers for each question).

Rocks & Minerals Binder Tips

• Add the Official Rocks & Minerals list to the front of your binder
• Keep your binder organized
• Add in lots of pictures (diverse pics for the same rock/mineral can be helpful)
• Add in characteristics of each rock/mineral, especially properties that aren’t obvious (hardness, SG, cleavage, etc.)
• I recommend adding in a section for geology vocab words
• Keep adding! As you take practice tests and attend invitationals, you’ll find more info to add
• Don’t be fully dependent on your binder; be familiar with the rocks/minerals, enough to ID them without needing your binder
• Don’t procrastinate creating your binder! The earlier you start, the better
