Mr. Hannemann was our guest on the latest podcast. He did a great job talking about what he was like as a student in middle school, and what he feels is important for young people to remember as they progress through middle school, high school, and college.

Here is a form, in which I'd love your input. This is a blog that showcases your scientific knowledge, talents, and work. Let it be your podcast.

Minerals

When you first heard that we would be learning about minerals, here were some of the initial comments:

• "So...... we're gonna learn about rocks....... OK......."
• "Are there really minerals in a bottle of mineral water?"
  
• "Diamonds, gold, and other gemstones are minerals. Can we keep the ones we work with?"
• "Aren't there minerals in the Fruity Pebbles I eat for breakfast?"

In the past few days in science, your view of minerals has likely changed. You've discovered that there are many different classes/types of minerals -- each with a unique set of properties that allows us to identify one mineral from another.
In your comment, completely answer the following questions. If you don't want your comment to be published, that is fine! Just let me know in the comment you leave.

1. Minerals are identified by their properties. What are some of the properties you used to distinguish one mineral from another? Why is it best to use more than just one or two of these properties?
   
2. Did some of the properties "work" better than others? Which ones were the most effective? Which were the least effective? Explain.
   
3. What was the most difficult part of identifying minerals?

Coke vs. Diet Coke Challenge

Crazy 8s: Don't let the title of this post fool you. This is not a taste test (although taste IS a property of minerals). Instead, we will test these objects' densities. Please follow the directions that are given below the slideshow.
