Have you ever wanted the special power to see in the dark? You can do it with night-vision goggles, or eyeglasses that use infrared radiation! Astronomers use similar technology to learn about the universe.
To write about infrared technology, you will compare and contrast different devices that detect infrared radiation. Here are some questions to guide your research:
What is infrared radiation?
How is infrared radiation different from visible radiation?
How do night-vision goggles work?
What does the Spitzer Space Telescope do?
What is a bolometer?
Are you ready? Begin by visiting the Web sites listed in Step 2. Look for answers to the questions above, and write down what you learned in the note-taking boxes.
With teacher supervision, you may use search engines to research other Web sites. You also can research infrared radiation at the library. When you are ready, follow Steps 3 and 4 to write your report.
Step 2. Research
Research answers for the questions you were asked in Step 1. Visit these Web sites. Take notes about them on this page, too!
