Challenge them to develop and test a hypothesis which determines the ideal environmental conditions for specially encapsulated sponge animals to emerge from their "cocoons". In the process, they learn the basics of how scientists design experiments, control variables, gather information, summarize and present data, and solve scientific problems. Grades 7-10
This program explores the mechanics of measuring wind speed and direction as well as the use of wind as an energy source. Students will also learn how wind occurs by finding out about the roles of temperature, air pressure and the sun. Graphics and animation will clearly illustrate these patterns. Students will also learn how hot-air balloons work in this exciting look at weather's invisible force. 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.
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.

Have you ever wondered how a weather forecaster knows what the weather will be like? In All About Meteorology, young students will see how meteorologists can predict the weather for the upcoming week and even a few months down the road through scientific deduction and high-tech equipment. Students will visit with Dr. Jon Nese, chief meteorologist at The Franklin Institute Science Museum in Philadelphia, to get an up-close look at the equipment that meteorologists use to forecast the weather and explore such concepts as the water cycle and air pressure. Through a fun, hands-on demonstration, see how students can set up their own mini-weather station to monitor conditions in their own areas. Part of the multivolume Weather for Children DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades K to 4.
Winter, spring, summer and fall. We know what happens in our own backyards at these times during the year, but it isn't the same everywhere in the world! When it's warm and sunny where you are, it might be very different in other places of the world. Why do the seasons change? And what causes different regions in the world to have different climates? These and other questions are answered in All About Climate & Seasons, where young students will learn about these yearly changes through engaging examples and explanations. A hands-on investigation shows the effects of direct sunlight on areas of the world, while Dr. Jon Nese, chief meteorologist at The Franklin Institute Science Museum in Philadelphia, demonstrates the concept behind the device known as an orrery.

Titration allows students to apply scientific concepts to discover what a titration is, how it is performed and how to determine when it is complete. Students see how this technique is applied in a number of real-world settings and become actively engaged in an experiment by using a scientific approach to determine the amount of vitamin C in a number of foods. Viewers learn about proper safety procedures as they watch a group of high school students gather, organize and present their data. Part of the multivolume Science Lab Investigations! DVD Series.

In The Laws of Motion: Hovercrafts, students will learn how to make and use models to investigate the principles behind the laws of motion. As they test and refine their project, students -- and viewers -- are encouraged to make predictions based on experimental evidence as they learn to calculate the effect of forces on the motion of objects. The concepts of Newtonian mechanics are investigated by using clear demonstrations and graphics, and students discover how technological advancements are built on scientific knowledge. Part of the multivolume Science Lab Investigations! DVD Series. Includes a Teacher's Guide.
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.
