To test the pretzel, crush a little bit into fine crumbs. To test the beans, mash them into a paste. Do not add water when you test the beans, yogurt or liquid part of Jerell's evidence. Write down your plan, and create a data table or tables that you will use to figure out who took Jerell's iPod. Check these with your teacher before you begin testing your samples. After you have tested your samples, use your findings to figure out who took Jerell's iPod.
