Erythemal Index for August 2000 through July 2001: Rotating Globe
The Erythemal Index is a measure of ultraviolet radiation (UV) at ground level on the Earth. UV exists to the left of the visible spectrum and is divided into three components (UV-A, UV-B and UV-C). UV-B (290-320 wavelengths) is the most dangerous form of UV radiation that can reach ground level. Atmospheric ozone shields life at the surface from most of the harmful components of solar radiation. Chemical processes in the atmosphere can effect the level of protection provided by the ozone in the

Growing and Graphing
Students visit a 2nd and a 4th grade class to measure the heights of older students using large building blocks as a non-standard unit of measure. They can also measure adults in the school community. Results are displayed in age-appropriate bar graphs (paper cut-outs of miniature building blocks glued on paper to form a bar graph) comparing the different age groups. The activities that comprise this lesson help students develop the concepts and vocabulary to describe, in a non-ambiguous way, ho

Black, who had covered for Plummer until Cullen arrived, was appointed to Cullen's position at the University of Glasgow. This move also marked a change in the direction of Black's research. He now began to investigate the nature of heat, a central topic in eighteenth-century chemistry.
