Describes a bubble activity related to the concepts of force and motion. Uses soap solutions for the task and evaluates students according to their performance in the problem solving process and garnering investigation results, which are conceptually based. Promotes and assesses science process skills. (Contains 20 references.) (YDS)

Explains the terms resonance and amplitude, the relationship between them, and the effects of resonance in our daily lives. Introduces pendulum activities that explain how resonance works. (YDS)

Presents the floral foam activity which explores the relationship between volume and mass. Focuses on helping students to enhance their critical thinking skills. (YDS)

Discusses physics, earth science, and physical science concepts that are challenging for students and teachers because they are difficult to understand and demonstrate. Identifies ratio and inverse-square as a unifying-concept approach according to the National Education Standards. Supports teaching based on student-centered activities, long-term…

Describes how to construct a simple motor from a coffee mug, wire, and magnets. Includes background information, student assembly procedures, troubleshooting, and extensions. (DDR)

Presents activities that integrate physics, earth science, and health. Students explore their own sensible temperature focusing on the physical processes of heat transfer. (DDR)
