The primary goal of this study was to examine the reliability of Rutkowski's Singing Voice Development Measure for use in the general music classroom, Grades 1-6. Results indicated that the rating scale, although originally designed for young children, is reliable for use when children in Grades 1-5 perform a short major song in solo. Results from ancillary problems indicate that (a) elementary children may have a better use of their singing voice when performing a major song than a minor song, and (b) a large portion of the children sampled did not have full use of their singing voice.

Basic understanding of nuclear science enhances our daily-life experience in many areas, such as the environment, medicine, electric power generation, and even politics. Yet typical school curricula do not provide for experiments that explore the topic. We present a means by which educators can use the ubiquitous webcam and inexpensive sources of radiation to lead their students in a quantitative exploration of radioactivity, radiation, and the applications of nuclear physics.
