Presents the "Before Technology and After Technology" lab where students first complete a simple lab and graph the data by hand and then repeat the lab using graphing calculators. Enables students to see how technology can make data collecting, graphing, and analyzing more fun. (JRH)

This description of the use of "probeware," i.e., hardware which connects to a microcomputer and works with the software to measure factors such as temperature, light, or motion in science laboratory experiments, uses as an example an experiment which would involve the measurement of pendulum motion using the "Precision Timer…

Presents an experiment that investigates the temperature of tungsten filaments using a car headlamp. Uses a spreadsheet program that facilitates extensive data manipulation. Gives students an awareness of the many mathematical techniques used in data analysis. (Author/JRH)

Presents research results on photosynthetic, carbon monoxide utilizing bacteria. Discusses applications of the research and offers three sets of experimental procedures and data that students analyze to determine which bacterium from a soil sample uses carbon monoxide fastest. (Contains 21 references.) (MDH)

Presents performance assessments, written by a team of Wisconsin science teachers, designed to see if students know, have practiced, and are able to perform the skills associated with science problem solving. (JRH)

An experiment accompanied by a series of writing exercises that engage students in activities that characterize scientific research is described. The exercise emphasizes experimental design and data analysis over technical manipulation. Possible issues for discussion and opportunities for collaboration and peer review are discussed. (KR)

Presents two experiments in which students examine the effects of touching and shaking on plant growth in common bush beans. (MDH)

Science interfacing packages (also known as microcomputer-based laboratories or probeware) generally consist of a set of programs on disks, a user's manual, and hardware which includes one or more sensory devices. Together with a microcomputer they combine to make a powerful data acquisition and analysis tool. Packages are available for accurately…

Discusses integrating mathematics/science with measurement for grades 6-12. Provides Web addresses for companies manufacturing data grabbers (instruments for gathering data in electronic form for graphing and analysis by graphing calculators and computers) and for sites offering instructional materials. Describes projects in architecture,…

Presents an experiment that measures the acceleration and velocity of a model rocket. Lift-off information is transmitted to a computer that creates a graph of the velocity. Discusses the analysis of the computer-generated data and differences between calculated and experimental velocity and acceleration of several rocket types. (MDH)
