This unit features student investigations into dry ice, whose intriguing and “sublime” behavior makes for a totally memorable learning experience. High interest and the captivating nature of the substance provide a strong motivational framework for students to construct essential understandings of inquiry, as well as deeper age-appropriate concepts of matter, gases, chemistry, and carbon dioxide itself.
The unit is designed to meet the dual educational challenge of providing compelling student-centered experience in scientific investigation and experimentation, while introducing aspects of the particulate theory of matter, phase change, nature of gases, and the history of science.
