Student Artifacts

Introduction: Students were given the following prompt:

"Can you build something that shows what you know about air and how the linked syringes work?"

Below are pictures of what 5th graders built. Please use the comment feature below to write what you think they were trying to show. What ideas about air? What kinds of relationships? And how did they use physical artifacts to represent these ideas?
