Sessions of our laboratory-based physics course have been "meeting" synchronously online instead of on campus due to the pandemic. Shifting to remote instruction prompted us to create online versions of the course. In the unit on global climate change, for example, we continued engaging students in documenting their initial and evolving…

This article describes a twist on the basic "Science 101" investigation of having students observe a birthday candle before, during, and after burning. It engages students in exploring the attributes of a candle, introduces them to the concepts of empirical observation and investigation, and involves them in developing and conducting a burning…

The Mole Concept is a learning cycle (patterned after University of Nebraska-Lincoln's ADAPT model) for the chemical unit "mole." Discusses objectives and activities involved in each phase of the cycle: exploration, invention, and application. Indicates the cycle is superior to traditional lecture-demonstration for teaching the abstract mole…

Explains that trial and error learning is an important way for children and adults to learn. Open-ended activities have great opportunities for error and eventual feedback for error reduction. (PR)

Three-phased learning cycles (exploration, invention, application) were introduced into general chemistry laboratories at Northland College (Wisconsin). Discusses each phase and its use in a learning cycle on the functional groups of organic compounds. (JN)
