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.

Grades 5-12.
Cobalt chloride crystals are commonly used in classrooms for chemistry experiments and demonstrations, primarily to study chemical properties and investigate reactions involving moisture and hydration. The most notable uses include:
-
Indicator for Humidity and Hydration: Cobalt chloride is a popular indicator for moisture because it changes color based on its hydration state. In its anhydrous form, cobalt chloride is blue, and it turns pink when it absorbs water. This property makes it ideal for demonstrating reversible chemical changes and teaching about hydration and dehydration reactions.
-
Le Chatelier€™s Principle Demonstrations: Cobalt chloride can be used to illustrate Le Chatelier's Principle. By adding water or applying heat to the crystal, students can observe the reversible color change, demonstrating shifts in equilibrium due to changes in temperature or the presence of a reactant.
-
Testing for Water Presence: Cobalt chloride paper, which is made using the crystals, is used in chemistry and environmental science labs to detect water vapor in various gases or liquids.
Due to its potential toxicity and the fact that it can cause skin irritation, cobalt chloride should be handled with proper safety measures, including wearing gloves and protective eyewear.
Specifically designed to dramatically and vividly show the classroom a pollutant in water, this kit is designed to permit students the opportunity of determining the presence of animal waste by seeing a dramatic color change that occurs in a lactose broth, students can determine if E coli are present. Grades 7-12.

A compact and economical Color Mixing Apparatus. This updated version of the classic three color light projector uses three low voltage, high power LED's to project easily-seen red, green, and blue light onto a white screen. The projector mounting allows the beam angles to be adjusted to vary the overlap of the three colored images. The intensity of each LED can be adjusted separately by a potentiometer to give a convincing white light or various shades of mixed colors. Colored shadows can also be explored in a darkened room. The set includes a wall mount power supply and manual.
