Comets

November 1, 2012

Gr 2-5-Rajczak directs readers' eyes skyward to observe a variety of phenomena. Although many of the images are stock photos, the variations in layout and inclusion of informative fact boxes and captions make these volumes solid introductions. Clear, well-labeled diagrams help explain topics such as refraction of light through a prism and orbits of comets. Step-by-step reviews of how lightning, rainbows, and auroras form conclude the volumes on those topics, reinforcing what students have just read. The other titles conclude with information on how to spot comets or shooting stars. Each book stands alone and can be purchased to update or supplement existing resources. Consider purchasing Comets and Stars together because of the close relationship of the topics.
