Tough as Diamond: Understanding Mineral Hardness for Earth Science

My name's Susan and I'm a tutor at the local middle school. The kids that I mentor wanted me to email you and let you know that they think your page (that's this page), on earth science, is very helpful, and we have been using it a ton this semester!

As a thank you they wanted me to reach out to you and give you another great resource they have been using and have found helpful, all about understanding minerals & their properties.

This group of kids really are wonderful and have come a long way in learning, they were hoping you would add the above link to your page, and because of their hard work, I told them they could have a surprise pizza party this Friday ;)

Good luck with that surprise party, Susan! - jb

Diamonds Pro

I get dozens of requests for links to sites that at first blush look just like this one and ... blah, blah, blah ... But on an impulse I looked at it ... and to my shock, I loved this site. The Reviews were brilliant.

They say: Getting the real scoop about diamonds isn’t easy. Who can you trust? Certainly not the salesperson trying to sell you a more expensive diamond. You also can’t trust the website that wants to sell you the diamonds that they specialize in. Diamonds Pro is here to tell you the things that nobody else wants to tell you — our goal is to teach you how to spend the least amount of money possible while buying a diamond that looks just as great (if not greater) than the more expensive stone they want you to buy.

A Home Guide to Kitchen Science Experiments

Good afternoon and greetings from Mrs. Ward's class!

I hope you don't mind me reaching out to you like this. I'm currently in the middle of a class project and was hoping you might be able to lend a hand. My students and I are working to revamp our outdated class website by adding a comprehensive resource section for students, parents and even other teachers. One of my students, Amy, found your webpage while searching for resources for our "science" category. It's a great page that we will most likely be utilizing!

As an additional requirement for this project, my students need to share a similar resource with the sites they've borrowed information from (sharing knowledge = good netiquette, as they're learning haha). So here's another resource Amy chose for your site - Joan Ward

High School Earth Science: Rocks and Rock Collections
I wanted to tell you that your resources are great. I do group tutoring and they really seem to enjoy it too. I'm actually writing to you on their behalf! They have decided that they would like to send you a suggestion of another resource that they really like - great information about rocks and minerals.

I think that it would make their day if you could set it up on your site with your other resources (YES! - jb). It really is a useful article with great information. Thats why I have agreed to write to you. Maybe it will even encourage the others to bring in their own resources to share. - Sincerely, Ms Kimberly McKnight's Class

There are rocks all around you – the canyons, mountains, and riverbeds, are all created from minerals. The earth’s crust is made of rocks and minerals with an inside core of molten rock and an outside crust covered by sand, water, soil, and ice. There are three main types of rocks which include igneous rock, sedimentary rock, and metamorphic rock. It’s important to study rocks as they suggest clues of the earth’s history. The breakdown of the rock layers show scientists how the land was formed and prior climate patterns in certain areas. To learn more about the various types of rocks and how they are formed, many people participate in rock collecting as a hobby. Here, you will learn about several aspects of rock creation and collecting ...

40 Common Minerals - Tungsten, Silver, Feldspar & more!
I just wanted to say that, as a science teacher, I have been using your page with information on rocks and minerals (http://www.dendritics.com/scales/gem-links.asp) for my lessons. It's been useful; thank you for making it!

Since your page was helpful to my classroom, I thought I would pass along another resource one of my students found that you might like to include: "40 Common Minerals - Tungsten, Silver, Feldspar & more!" - http://www.larsonjewelers.com/40-common-minerals.aspx

It lists 40 common minerals and their uses, making it a handy reference guide. I thought your visitors might find it beneficial too. (Plus, I would love to show my student that the page he found is incorporated on your website...makes him feel special, haha!) Hope I could help!

Happy Holidays, Ms. Sarah Hess

Marian's Paintings.
Life is food, art is life everlasting. A fullness in your belly and a relief in your soul. As Marian Dioguardi, artist, says: I am an independently trained painter. My favorite teachers are Ed Stitt, Janet Monafo, Paul Rahilly and Barney Rubenstein, who have all contributed to my training. I paint still moments inspired by simple beauty in a simple way. I am a purist. Paint, panel, pallet knife. I am challenged by color and contrast, form and shape and the way in which objects occupy two-dimensional space.
