This is a powerpoint which guides students to discover the outcomes of Christopher Columbus' exploration. Students will be given a chart to record their evidence and hypothesis. Directions are explained in the slideshow but the students are only allowed to ask the teacher yes and no questions referencing each slide. Each slide is a different artifact or image and in this inquiry each slide represents one of the outcomes. This is a great way to have students activley engage and use reasoning skills to come to their own conclusions. My students always enjoy these!
