Teacher created. Amazing visual demonstration as warm and cold fronts clash. Bring the earth sciences to life with the illuminated density flow model. Engage your students with dramatic simulations of many of the earth’s dynamic natural pro..

Amazing visual demonstration as warm and cold fronts clash. The density flow model junior, like the larger model (Z19342M), is a teacher demonstration apparatus that uses simple principles to explain the most complicated concepts in the Earth sci..

This model vividly demonstrates the character and interaction of air masses, pressure, and heat energy. To help explain weather forecasting, the basic warm and cold fronts are in transparent plastic, so the student can visualize their movements and rela..

This three-dimensional demonstrator creates a water cycle as it occurs in nature. A fascinating, ingenious experimental model that actually causes the rain to fall, then evaporate in a continuous cycle. It also graphically shows distillation of wate..

This three-dimensional demonstrator creates a water cycle as it occurs in nature. A fascinating, ingenious experimental model that actually causes the rain to fall on the terrain, flow down the slopes, form a body of water, then evaporate in a conti..

This three-dimensional model promotes a basic understanding of cloud types in the classroom or outdoors, plus science and math skills. Removable labels let students identify cloud structures and altitudes on the 24" W x 18" H model. Includes..
