This 8 slide PowerPoint guides students through the process of forming and testing a hypothesis while learning complimentary colors. Each set of complimentary colors is covered and students always enjoy working through each section of the presentation. You will need a large well lit white wall or ceiling and a way for all students to view the PowerPoint slides. This activity can be taught in lecture style, small groups, or independently. I like to teach this lesson in conjunction with my Color Theory PowerPoint as sold on TpT.
