Learning Imaging Techniques!

During this activity, students are introduced to the concepts of the unit's "grand challenge." They generate ideas for solving the problem, first independently, then in small groups. Finally, as a class, students compile their ideas with a visual as a learning supplement.
This activity presents students with a need in society and asks them to consider a method for finding a solution, also known as the engineering design process. As engineers, students must first identify the need for a painless, yet reliable method for detecting cancerous tumors; then, students will define the challenges which must be considered in the design. In the next phase, research will begin but before researching, students must identify the information they will need to acquire through their research. Engineers of all types constantly follow the engineering design process, with the first and most crucial steps being identifying the need in society. Like engineers, students must learn to apply their peripheral knowledge to solve the identified need. In questions 1-4 of the Generate Ideas section of the handout, students must identify a need in society and consider how it can be fulfilled.
After this activity, students should be able to:
- Apply their background knowledge to begin solving the challenge.
- Identify gaps in their knowledge needed to solve the challenge.
