Uses a computer interface to measure terminal voltage versus current characteristic of a variety of batteries, their series and parallel combinations, and the variation with discharge. The concept of an internal resistance demonstrates that current flows through the battery determine the efficiency and serve to introduce Thevenin's theorem.…

Integrating curriculum is important in helping children make connections within and among areas. Presents a class project for kindergarten children which came out of the students' interests and desire to build a reptile exhibit. (ASK)

Introduces an activity in which students prove that milliliters and cubic centimeters are equal. Assigns students in groups for the activity and starts with a realistic story to increase student interest. (YDS)

Introduces a science experiment in which students investigate the wind-leaf relationship by using a leaf blower. Assesses damage differences between leaf species under wind stress. (YDS)

Presents an inexpensive activity to stimulate student interest in biotechnology that was developed in partnership with a biotechnology company. Focuses on the use of DNA by a commercial laboratory; describing the analysis procedure; important uses of DNA technology in modern society; and ethical, social, and legal issues related to biotechnology.…

Presents an activity to help students learn the basics of effective communication. (YDS)

Surveys 15 introductory biology textbooks for their presentation of the scientific method. Teaching the scientific method involves more than simplified steps and subjectivity--human politics, cultural influences, and chance are all a part of science. Presents an activity for students to experience the scientific method. (Contains 34 references.)…

Introduces an activity on the changes of matter. Uses different colors to represent the phases of water in different temperature ranges and discusses the phase changes of other chemicals. Includes an activity sheet. (YDS)

Presents an activity involving balloons to help students understand characteristics of polymers. (MKR)

Presents an activity in which students trace the movement of the continents over the past 600 million years to help them understand how the continents' size and position have changed over time. Includes map puzzle pieces. (MKR)

Summarizes seven pilot projects in which industries and schools collaborate to provide an outdoor education experience for students. Industry provides the context by allowing schools to use wilderness land rich in natural ecosystems. Includes brief description of the process of establishing such a partnership between schools and industries. (DDR)

Presents five interactive, computer-based activities that mimic scientific tests used by sport researchers to help companies design high-performance athletic shoes, including impact tests, flexion tests, friction tests, video analysis, and computer modeling. Provides a platform for teachers to build connections between chemistry (polymer science),…

Presents activities and investigations that provide a trail of physics-related topics for students to investigate at a bowling alley. (JRH)

Describes how to construct a safe, inexpensive rocket for use with young children. (MKR)

Presents a quick and simple exercise that demonstrates what is meant by the term "statistically insignificant." Demonstrates the bell curve distribution, the relationship of a sample to the population it is supposed to estimate, and the t-test. (DDR)
