This is an engaging simulation where the class is divided into the “old” and “new” worlds. Each student is assigned a specific animal, plant, or disease which originated from their respective world. Students then make the treacherous journey across the Atlantic ocean (I use a piece of blue butcher paper) and exchange their item with someone else. You can choose to make index cards representing the items if you'd like to. Student handout with questions is included. The list for the items can be found as the preview file.
