In this paper we present activities that can help students deepen their understanding of DC circuits and develop practical competences. The students investigate electric properties of commercially available conductive thread and solve a practical design task using the thread. The activities follow the framework of investigative science learning…

The United Nations has proclaimed 2011 as the International Year of Chemistry and, as part of that designation, has invited teachers worldwide to participate with their students in the Global Water Experiment (IYC 2010). Students have the opportunity to take part in four different water-related investigations to assess water quality and then share…

In this article, the underlying logic of experimentation is exemplified within the context of a photoelectrical experiment for students taking a high school engineering, technology, or chemistry class. Students assume the role of photochemists as they plan, fabricate, and experiment with a solar cell made of copper and an aqueous solution of…

This book presents essential learning approaches. It introduces educational and training activities, as well as various innovative methods aiming at the development of practical skills, in order to strengthen the continuous process of environmental education, and in particular the education for sustainable development (ESD). In doing so, it…

This unit is designed to stimulate interest in math, engineering, aerospace, and physics through the exploration of rocketry science. It serves as a ready source of information dealing with the subject of rocketry and provides directions for completing a variety of hands-on rocketry science experiments, including the design, construction, and…

Discusses the importance of laboratory experiments in which students were given a few guidelines and small groups had to design the experiments. Describes the old and new orders of laboratory projects and the effects of change. (CW)

Discusses how, in two three-week sessions, the Terre Haute (Indiana) college offers selected students a hands-on approach to all aspects of engineering from design and lab work to technical writing. Describes a group project requiring students to study and experiment with simple research problems. Lists 20 project ideas. (MVL)
