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)

Describes an activity for determining how long and when a tree lived by comparing its ring sizes with local precipitation records. Suggests benefits for this type of dendrochronology activity. (TW)

Discusses a graphical analysis method used in the physics laboratory. Shown are various kinds of graphs to illustrate the relationship between two variables. A procedure for deriving equations from laboratory data is described. (YP)

This activity uses ice crystals to introduce middle school and high school students to the collection, preparation, examination, and manipulation of scientific data. (PR)

Describes an activity in which students examine hypothetical exposure to toxins by being showered by different colored pieces of confetti over several visits to exposure sites. Students record quantities of confetti that stick to packing tape. Colors correspond to different toxins posing different health problems. Students process their findings…

Presents a unit that uses remote-sensing images from satellites and other spacecraft to provide new perspectives of the earth and generate greater global awareness. Relates the levels of Bloom's hierarchy to different aspects of the remote sensing unit to confirm that the concepts and principles of remote sensing and related images belong in…

Describes methods for creating integrated multimedia documents using recent advances in print, audio, and video digitization that bring added usefulness to computers as data acquisition, processing, and presentation tools. Discusses advantages of digital documentation. (JRH)

Presents examples of what can be done with CD-ROMs to enhance learning about weather and climate. Topics include hurricanes and tropical storms, climatic studies with CD-ROM archives, and assessment. (JRH)

Presents activities using thermocouples to investigate the temperatures at which candles burn and popcorn pops. (MKR)

Describes student-friendly data sets accessible over the Internet that enable students to use large sets of real data to create graphs, apply basic statistical techniques, construct models, and draw conclusions about how the earth functions. Lists useful online data sets. (JRH)

Developed is a classroom activity that illustrates the scientific method. The importance of observation, interpretation, and prediction is discussed. The activity uses pictures of the surface of Mars. (KR)

Describes how students in a geoscience course are introduced to geographic information systems (GIS), a computer-assisted system for the acquisition, storage, analysis, and display of geographic data, through a practical experience involving collecting data and inputting it into a GIS program called IDRISI. (MKR)

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)

Presents an activity in which students investigate the formation of solid ammonium chloride aerosol particles to help students better understand the concept of acid rain. Provides activity objectives, procedures, sample data, clean-up instructions, and questions and answers to help interpret the data. (MDH)
