The first simple circuit is to be built. In doing so, the basic properties and important components are familiarized.

The conductivity of various materials and objects is qualitatively investigated.

The series and parallel connections are qualitatively investigated on the basis of the brightness of lamps. The experiment forms the basis for logical circuits and measurements in branched and unbranched circuits.

The two simplest logical circuits are to be developed independently. They also serve as preparation for the household circuits.

Simple electrical circuits from practice are to be reproduced at nine different stations. The focus is on the multiple application of series and parallel connections of switches and lamps.

In a simple circuit, the current is measured at different points.

The characteristic curve of an incandescent lamp and an ohmic resistance are measured and evaluated.

The experiment investigates which factors besides temperature have an influence on the resistance of a wire. Instead of a wire, graphite lines are examined on conventional and therefore poorly conducting paper.

Kirchhoff's laws are derived by the measurement of voltage and current and the calculation of the resistance.

Several puzzle tasks stimulate thinking. The terms series and parallel connection are practiced and competencies in the construction of electrical circuits are consolidated.

In a series connection with two lamps, the voltage is measured and evaluated between different points.

The electrical power is examined based on the brightness of lamps and the proportionality to current and voltage is discovered.
