Objective Many students are totally unfamiliar with the term medical imaging.
This lesson will cause the students to attend to a particular body part and draw conclusions based on what he/she is able to see and what is implied but not seen. The teacher may use this exercise to explain that medical imaging allows radiologists to go far beyond what the students have experienced and see images of the patient’s insides without cutting them open.
Materials Needed Flashlight, dimly lit room. (See Figure 9 at end of unit.)
1. Close the curtains.
2. Turn on the flashlight.
3. Hold the flashlight in one hand.
4. Place the palm of the free hand over the face of the flashlight.
Observations and Analysis
1. Students will notice the webbing between their fingers.
2. Students will notice that more light comes through the webbing than the fingers or hand.
3. The students will see the hand as being quite red and will probably associate that redness with the fact that there is blood inside the hand.
4. Have students discuss what they feel the flashlight has enabled them to see or think about, that they would have otherwise ignored.
