Engineering Challenge
Students will design and construct a physical model that demonstrates thermal expansion of saltwater. Their model must demonstrate thermal expansion within a class period time frame. The expansion must be the result of warming only. Expansion must be measurable.
Students will:
- Identify the criteria and constraints.
- Consider the types of materials that could be used to create a working model.
- Propose two or three possible design solutions.
- Draw the final design solution, indicating the materials to be used and how the system works.
