Visualizing Chemical Phenomena in Microdroplets
Journal of Chemical Education, 2010Phenomena that occur in microdroplets are described to the undergraduate chemistry community. Droplets having a diameter in the micrometer range can have unique and interesting properties, which arise because of their small size and, especially, their high surface area-to-volume ratio. Students are generally unfamiliar with the characteristics of small

LEARNERS’ EXPLANATIONS FOR CHEMICAL PHENOMENA [PDF]
Chem. Educ. Res. Pract., 2000 There is a growing body of research which explores the nature of explanation in science classrooms. The vast majority of this work highlights the teacher’s role as explainer of scientific phenomena, while little has explored the quality of learners’ own explanations.

Physical phenomena‐‐chemical phenomena: do pupils make the distinction?
International Journal of Science Education, 1989Abstract This research explored: (a) the representations and conceptions of some Greek pupils of the concept of chemical reaction, and (6) the ways in which these pupils categorized a set of physical and chemical transformations of matter. The results show that pupils group physical and chemical phenomena in different ways, using different criteria ...

Physical-Chemical Phenomena and Molecular Properties
1984The importance of air-water exchange processes as determinants of the environmental behavior and effects of natural and anthropogenic chemicals is discussed. The various exchange mechanisms of diffusion (volatilization or absorption), deposition in association with particles both dry and wet, dissolution in rainfall, spray transfer and bubble transfer ...
