Presents a mini-environment project as a valuable teaching tool for presenting ecology. The procedures for setting up a mini-desert in the classroom are presented as a model. Basic components of the mini-environment project are also included. (HM)

Describes an exercise in which students convert lithostratigraphic columns into chronostratigraphic columns, infer paleolatitude using paleomagnetic data, interpret depositional environments, determine the timing of deformation and terrane collision, construct models, and synthesize the results into a geologic history. Background data, procedures,…

Describes creating a Model Aquatic/Terrestrial Ecosystem for use in helping students understand how water moves beneath the ground's surface. The model is constructed from a fish tank using rocks, soil, gravel, clay, and organic materials. Author describes possible cooperative-learning and problem-solving activities that can be done with this…

Describes a student project for building a laboratory balance. (PR)

Describes how a teacher can give their students the challenge of designing and building model balloons or blimps. The project helps students learn the basics of balloon flight and what it really means to be "lighter than air." (PR)

Describes the development, implementation, and results of a pond life elementary student research project. Utilizing the pond life example, provides guidelines for children's research projects including the implementation of the K-W-L (know-want to know- learned) strategy with the children's reports/projects. Provides resources utilized in the…

The Lawrence Hall of Science, a science center, seeks to replicate real-world engineering at the "Ingenuity in Action" exhibit, which consists of three open-ended challenges. These problems encourage children to engage in engineering design processes and problem-solving techniques through tinkering. We observed and interviewed 112…

Discusses a teaching method using investigational skills for Nuffield A-level Physics including assessment technique, change of the assessment criteria, advice for choosing the topic, and future development. (YP)

The acronym STEM--the teaching of science, technology, engineering, and math--now a familiar term in education, is evolving into STEAM--STEM plus "A" for art. Educational researcher Martin Storksdieck's studies have shown that infusing art into STEM allows for "a different way of perceiving and knowing and dealing with the world, as a means to…
