MRI – A Closer Look
Learning Objectives
- Understand the basic concept of how MRI machines use magnetic forces to create images of the body.
- Identify the role of magnets in the functioning of an MRI machine.
- Recognize how different parts of the body respond to magnetic forces during an MRI scan.
- Explain the significance of MRI as a non-invasive tool for medical diagnosis.
Introduction and Hook
Introduce the concept of MRI as a non-invasive diagnostic tool, emphasizing its significance in medical science.
Direct Instruction
Explain how MRI machines use powerful magnets to create detailed images of the body's internal structures.
Discuss the role of magnets in MRI machines and how different body parts respond to magnetic forces during a scan.
Guided Exploration
Watch a video demonstrating how MRI machines work and the science behind magnetic resonance imaging.
Encourage students to ask questions about the MRI process and discuss their observations from the video.
Hands-On Activity
Conduct a simple experiment to demonstrate magnetic forces using magnets and various objects to show attraction and repulsion.
Have students record their observations and discuss how these principles relate to MRI technology.
Independent Practice
Assign students to research and present on how MRI technology has advanced medical diagnosis and treatment.
Check for Understanding
Use the 'Positions and Directions' assessment to evaluate students' understanding of spatial awareness, which is crucial in interpreting MRI images.
Review and Reflection
Facilitate a class discussion on the importance of MRI technology and its impact on healthcare.
Encourage students to reflect on what they have learned about magnetic forces and their applications in medicine.
Assessment and Extension
Administer the 'Describing Motion' assessment to gauge students' understanding of motion concepts, which are foundational to comprehending MRI technology.
Encourage students to explore further by designing a simple model demonstrating magnetic attraction and repulsion.
