Science Class Today

Today in chemistry class my students extracted copper from copper sulfate by combining the copper sulfate solution with iron. Who would have thought such a simple process can make so much money over the past 200 years. My students did it in about 35 minutes! What a modern world that we live in.

I am really glad that you have visited my blog.
Thanks and I hope to see and hear from you soon.
