Abstract
"Mobile Chemistry" is the first textbook designed specifically for the tablets and other mobile devices. This is the textbook of the 21st century. It consists of interactive exercises which allow one to quickly check their knowledge. Instead of filling the gaps, or combining elements by drawing pencil lines, it is enough to drag items using hand or a stylus. It Ii includes video clips depicting chemical experiences, explaining difficult issues, or showing otherwise unavailable effects in the school environment. Thanks to modern chemical sensors connected to the tablet PASCO students can perform an experiment by themselves. They help students develop their research skills, learn the analytical work as well as the principles of sampling and testing their composition.
