(Nothing is DUE!) Yesterday we looked at the Silk Road in detail and also listened to music from the famous cellist Yo-Yo Ma. We also took notes on trade in Africa and between Europe and Asia. One of the things that was traded was salt. Did you know that the word salary came from Roman soldiers that were paid partly in salt? Salt was an extremely important mineral a thousand years ago because it kept food from spoiling. It is also essential to proper health functions of the human body!
