In this program, concise explanations of the various types of precipitation provide students with insight into how rain, snow, sleet, hail, fog and mist form, as well as how the water cycle -- evaporation, condensation and precipitation -- constantly "recycles" water around the world. Students will also learn how the density of water changes in different states. See typical weather patterns across North America, and watch how a ski resort keeps slopes looking white. One of six volumes in the Weather Fundamentals DVD Series in the Schlessinger Science Library. Part of the Schlessinger Science Library in Action Collection. This title correlates to the National Science Education Standards for Earth and Space Science -- structure of Earth's system, Earth's history and Earth in the solar system. A Teacher's Guide is included and available online that features additional information on the topic, vocabulary words, discussion questions, follow-up activities and lists of recommended books & Internet resources. 23 minutes. Grades 4 to 7.

Discover how scientists are able to learn about the world around us by studying how light interacts with matter. Spectrophotometry gives students an understanding of the principles of spectral analysis and explains the relationship between absorbance and transmittance. Students then go inside the lab to put this information into action as they perform serial dilutions, develop a standard curve and determine the concentration of aspirin in two unknown solutions using a spectrophotometer. In the process, they use proper scientific procedures and come to understand that measurement errors may affect calculations. Part of the multivolume Science Lab Investigations! DVD Series. Includes a Teacher's Guide.
