Pair up with another student who has a similar item. Work together to identify the components of your objects. Write down your ideas with Crayola® Erasable Colored Pencils. For example, a marker has a plastic barrel, end plug, tip, cap, and color. Try to identify what material is used to make each part--wood, plastic (and what is plastic made of?), paper, rubber, wool, cotton, wheat, corn, sugar?
