AP9157 - $23.65
Perform a safe, microscale simulation of acid rain formation in a plastic bag. Chemicals react to form a visible brown cloud of nitrogen dioxide which, in turn, acidifies water present in the system. An acid–base indicator shows the speed and degree...
FB0010 - $32.75
Automobiles and factories belching smoke and fumes into a toxic, unbreathable atmosphere. A pristine pond and a deadly rainstorm. Create this dramatic scenario for your class!   A micro environment is created in an aquarium where sulfur and nitrogen...
FB1025 - $38.75
This oil polymer demonstration will undoubtedly capture your students’ interest, stimulate scientific inquiry, and will heighten their awareness of the emerging environmental pollution issues facing our society.   A new form of hydrocarbon stabilization...
FB0011 - $70.41
When nitrogen and oxygen—the two primary components of the air we breathe—combine under certain conditions the results can be devastating. In this demonstration nitrogen oxides are generated by the dissolution of copper in nitric acid and the resulting...
