Striding into the Scientific Future - Physics Lessons

Big Idea
Biomedical imaging has allowed great advances in diagnosis, but no single technique is adequate to address all issues. It is important to understand the underlying physical principles in order to appreciate the diagnostic possibilities of each method.
Essential Question
What are the underlying physics principles in biomedical imaging and how do they inform individuals on use of imaging?
Learning Cycle
Lesson Title & Description
Objective
Students will:
Class period & week
Engage

Biomedical imaging
Computer research and class discussion. Poster creation and mini-presentation.

Compare and contrast imaging methods both in groups and as a class. Develop a poster of their assigned methods.

Week 1
Days 1-5
Explore

If the facts don't fit the theory, change the facts
Reading and group discussion

Read about Einstein’s 1905 papers and discuss implications for imaging methods

Week 2
Day 6
Explain(1)

Detection detective
Lecture and rotation through student and teacher generated stations to consider the big picture of biomedical imaging.

Use physical principles to describe how the imaging systems in Biomedical imaging work using class materials from that lesson. Organize by principle and detection capability

Week 2
Days 7-8
Explain(2)

The photoelectric effect
Poster making to show physical principle.

Creation of group posters explaining the photoelectric effect and how one imaging technique works.

Week 2
Days 9
Apply
The right tool for the job: Diagnosis Spectrum
Using a provided scenario, students will determine the most appropriate detection method to get information about the condition. Discuss the scenario as experts might, and close after seeing what actually happened.

Students will watch a section of a medical TV show (i.e. House MD) and suggest appropriate imaging techniques to be used and why. Will discuss as a group of experts, and then compare their findings with those of the show.

Week 2
Days 10-11
Final Project

Thinking inside the box: dangers of tanning beds
Debate.

Debate about the regulation of tanning beds using physical principles to support opinions.

Week 3
Days 12-14
