This site can be used for information gathering. Teachers can design instructional activities to help students learn how to use their cell phones as an anytime, anywhere research and information-gathering device. For example, while on a trip to historical Williamsburg, Virginia, a teacher tells his class to send any questions that occur to them to the free information site ChaCha. One student wonders why a certain building was constructed in such an odd way. No tour guides are around to help, so he calls 1-800-chacha, asks his question, and gets a text-message answer back in minutes.
