There are superb tools available using calculators and probes that enable authentic math and science activities in elementary, middle and high school. These tools cost far less than desktop computers. For example, dip the temperature probe in a stream at different times of day and use the data to create a graph from which to discuss the changes.

Handheld computers can also have the same probes (sensors) attached that collect data, and then the PDA (handheld computer) in turn connects to a desktop Mac or Windows computer system and uploads the data for further analysis and exploration.
