Learn what air pollution is and how weather and geography affect it. Conduct experiments to test the air that you breathe everyday for pollutants. This kit comes complete with instruction manual, the chemicals and apparatus needed to conduct several air quality tests.
The 15 fossil specimens in this collection illustrate the animal and plant evidence found in various strata. Representative fossils from this era are the oldest known, coming from the Cambrian through the Permian periods. Grades 7-12.
The Earth Science Book Plus Series provides colorful teaching models and reproducible activity cards that teach children about earth science. The models are made of resilient, non-toxic, EVA foam, with removable pieces that stimulate problem-solving skills and develop small motor skills. The book covers contain background information, activities and extension ideas. Teachers can cut out the task card and use it in a learning center or as a group activity. The models are 10" x 14.5" x 3/4" thick. The teaching model illustrates volcanic action and shows how igneous, sedimentary and metamorphic rocks are formed. Available in French. Grades K-6.
With the full-size kit, demonstrate important density concepts to an entire classroom. Challenge students to use scientific inquiry techniques to explore geology, meteorology, freshwater and saltwater systems. Using the illuminated flow of colored fluids, students can visualize abstract concepts related to plate tectonics, sea-floor spreading, air masses, fronts, air pressure, winds, ocean currents, thermoclines, haloclines, upwelling, El Nino and more. Dimensions: 44"L x 6"H x 3.75" W. 72-page manual.
