This experiment designed for beginning physics students, is related to postal regulations restricting the size of envelopes. A graph is constructed that allows for testing the mailability of envelopes. (MP)

Explores strategies in the situation of a runner trying to evade a tackler on a football field. Enables the student to test intuitive strategies in a familiar situation using simple graphical and numerical methods or direct experimentation. (JRH)

Describes two spreadsheets for producing acid-base titration curves, one uses relatively simple cell formulae that can be written into the spreadsheet by inexperienced students and the second uses more complex formulae that are best written by the teacher. (JRH)

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 three computer programs which operate on Apple II+ microcomputers: (1) a menu-driven graph drawing program; (2) a simulation of the Millikan oil drop experiment; and (3) a program used to study the half-life of silver. (Instructions for obtaining the programs from the author are included.) (JN)

Discusses the uses of thermistors in teaching electronics and semiconductors. Describes how to experimentally measure and graph the characteristics of a thermistor. Suggests one possible approach to understand the shapes of the characteristics. (CW)

Describes a hands-on lesson in magnetism designed to be used with upper elementary grade students. Emphasizes structured experiences which involve the student in measuring, data collecting, graphing, and extrapolating information. (TW)

Presents a cooperative activity between home and school in which parents and students examine the growth of a variety of bulbs. Bulbs are taken home to sprout and returned to school to monitor their growth. Students gather data, hone observation and graphing skills, and communicate with their parents on the project. (MDH)

Describes a freshman chemistry experiment designed to introduce scientific methodology, provide practice in measurement skills, and illustrate a fundamental chemical relationship (conservation of volume). Provides the experimental design, a materials and equipment list, sample calculations, and results. (JM)

Effects of microcomputer-based laboratory (MBL) exercises and level of cognitive development on high school biology students' ability to construct and interpret line graphs were investigated. Forty-six students enrolled in general biology classes at a rural high school volunteered to participate in the study. These students were administered…

This publication provides information and activities for teaching about vegetables and process skills including observing, classifying, collecting and interpreting data, inferring, measuring, and predicting. There are 12 lessons. Lessons 1 through 5 pertain to growing, rinsing, and observing sprouts. Lessons 6 and 8 through 11 deal with tasting…

Describes a two-week lesson on electric fields that combined lecture, interactive video, lab experimentation, computer spread sheets, and computer-assisted-graphing. (PR)

Provides an example of the integration of science and mathematics learning of one high school physics student in a constructivist classroom. Discusses the student's integration of mathematical and nonmathematical representations and of different mathematical representations in a nonuniform acceleration experiment. Describes a model for integrating…
