Ask your class to identify each of 12 different samples by determining their density. Each cylinder varies in size and density since it is constructed of a different material. All are 1/2" in diameter and vary in length. This kit includes: 12 samples, an attractive wood storage rack coated in linseed oil for protection from wet specimens, and detailed instructions with theory. Samples include: aluminum, brass, copper, acrylic, pyrex, rubber, delrin (plastic), PVC, PTFE, nylon, poplar and oak.
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.
This program looks at the wide range of climates in North America and around the world, and examines how factors such as the sun, wind, temperature, precipitation and position of Earth determine the weather for a particular region. Live footage, vivid graphics and a hands-on experiment help to clearly illustrate these concepts. 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 and Internet resources. 23 minutes. Grades 4 to 7.
Did you ever wonder how weather forecasters predict the weather? This program looks at how meteorologists gather and interpret current weather data. Students will be introduced to everything from weather maps, weather stations and satellites to airplanes, weather ships and weather balloons. Students will also learn how to read a meteorological weather map and see the office of the National Weather Service.

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.

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.

24" x 36" full color laminated poster. This poster describes all ten divisions of the plant kingdom. Many representational species are shown including the four divisions of extinct plants. This poster is an ideal partner to our Animal Kingdom Poster (16339). Both posters are great for life science classes, but the non-technical presentation makes them popular with both animal and plant lovers alike.
