In this article, Karen Bucci describes how she incorporated her iPad with the wireless SmartScope iGO microscope and Wi-Viewer app to teach her fourth-grade class the science module "Ecosystems" by National Science Resources Center's Science and Technology for Children (STC) (1996, 2005). A main idea in the unit is the importance of…

To avoid a tedious task for recording temperature, a computer was used for calculating the heat of crystallization for the compound sodium thiosulfate. Described are the computer-interfacing procedures. Provides pictures of laboratory equipment and typical graphs from experiments. (YP)

Describes a series of laboratory experiments and computer simulations of the motion of electrons in electric and magnetic fields. These experiments, which involve an inexpensive student-built electron gun, study the electron mean free path, magnetic focusing, and other aspects. (Author/HM)

Presents activities, experiments, demonstrations, and equipment for physics instruction, including computer applications of sports biomechanics, vibrating magnetometer, alternative uses for an environmental comparator, CMOS integrated circuit logic tutor, and an activity demonstrating positive and negative leakage.

This ERIC Digest presents a brief description of some applications and findings of the microcomputer in science classrooms. It is suggested that microcomputer simulations are at least as effective as hands-on experiences for some cognitive outcomes and may in fact enhance these outcomes when the simulations are sequenced to follow hands-on…
