Physical Science, New York EditionUnit 3:
Energy on the MoveUnit Project 2Project Type: Technology
Divide the class into small groups, have each group research medical procedures that use waves, sound, or light to form diagnostic images. Procedures may include MRI, CAT scan, X rays, thermal imaging, or ultrasound. Have students create a news broadcast about their particular procedure to demonstrate how their image is formed, its benefits and limitations, and any related health risks. Alternative Procedure:
Divide the class into groups, have students choose a specific type of diagnostic imaging. Have each group discuss the history of diagnostic images, how the image is formed, and its risks and/or benefits. Challenge students to develop a potential solution to any risks or problems that the diagnostic imaging creates. Allow each group to present their finds and solutions to the class. Resources:
These sites will help students research medical procedures that use waves. History in the Medical Field
