Although laboratory work is considered a significant factor in helping students develop their science process skills and cultivate alternative knowledge construction, there are still gaps in the selection, integration, and implementation of the basic elements in physics laboratories. In this study, three modified guided discovery and conventional…

The so-called Diet Coke and Mentos experiment is initiated by dropping Mentos candies into a bottle of Diet Coke or other carbonated beverage. This causes the beverage to rapidly degas, causing foam to stream out of the bottle. Simple application of the gas laws leads to the straightforward prediction that ejection of greater foam volume is…

Women are underrepresented at multiple levels of physics education. One avenue for understanding the classroom experiences that perpetuate underrepresentation is physics identity, defined using the three dimensions of recognition, performance, and competence. Existing literature suggests that women tend to have a much weaker physics identity than…

Dimensional Analysis (DA) is shown to play a pivotal role in the teaching of Science, Technology, Engineering and Mathematics (STEM). This article summarizes the basic rules and corollaries of DA and addresses (1) the importance of using DA with mathematical functions; (2) how to use DA in a science/engineering laboratory based discovery approach;…

Advocated is the use of interactive centers to supplement existing classroom laboratory experiences. Activities found in the center and modified classroom versions are described. The problems that arise when primary students meet sophisticated exhibits is discussed. (KR)
