The kit contains about 15 different components with which a number of experiments can be performed. The components are designed so that students can quickly and easily perform their laboratory work. The kit can show how the following forms of energy are generated:

Supplier: CORNELSEN EXPERIMENTA

Used in electrochemistry. Voltage, max 1.5 V. The unit is divisible and consists of glass beaker, cylindrical zinc electrode, plastic beaker, carbon electrode, manganese oxide, crocodile clamps and lid. Fill with ammonium chloride solution (20%).

Supplier: 3B Scientific

Function generator with external sweep function and power amplifier for use in versatile student and practical experiments covering simple harmonic oscillation, AC electricity and induction. Featuring illuminated, digital display for frequency, signal form, offset and other parameters.

Supplier: MOLLER THERM

Radiometer according to Crookés. Consists of a glass container on foot with low air pressure and needle-bearing spinner with four vertical mica discs. The discs are black on one side and shiny on the other. The discs thus absorb radiation differently. The higher temperature of the dark side means that the air molecules get greater kinetic energy in collision with the dark side of the discs than with their shiny side. The result is that the spinner starts to rotate.

With the equipment, centrifugal forces that arise during a body's rotation around a specific axis can be measured and examined. The device consists of a plane with a path for a cart. On the underside there is a vertical shaft that is mounted in a bearing. The plane is made to rotate with a laboratory motor connected with a drive belt to the bearing. The experimental trolley is placed on the track and prevented from leaving the track by two bent steel wires. A wire is connected to the trolley that runs over a pulley and on to a dynamometer.

Supplier: GR NNA PLASTEMBALLAGE AB

The set is primarily intended for the upper level of elementary school or the equivalent level of knowledge. It is suitable for both demonstration and laboratory use. The kit can be used in any room with access to water. The kit includes everything needed with the exception of table salt, rubbing alcohol, cotton and cardboard sheets. The material is stored in a specially designed wooden box. Through a wealth of detail and many combination possibilities, basic physics experiments can be carried out in a number of different areas. Examples of attempts:

Supplier: 3B Scientific

Highly evacuated electron tube with focusing electron gun and fluorescent screen (90×60 mm) inclined relative to the beam axis, so that the path of the beam can be seen and the effects of electric and magnetic fields can be studied. The electron beam can be deflected electrically in the electric field of the built-in plate capacitor, and magnetically by using an optional Helmholtz coil pair D. By adjusting the electric field so that it cancels the magnetic deflection, it is possible to determine the specific charge e/m and the velocity of the electrons.

Supplier: 3B Scientific

Tube holder to support all S series electron tubes for easy and safe operation. The five pin sockets for the tube are concealed inside the tube holder. A cathode protection switch is integrated into the tube holder, to protect the heated cathode from excessive voltage. The base plate has a slot for attaching the Helmholtz pair of coils S.

Supplier: CORNELSEN EXPERIMENTA

72 series-connected semiconductor elements, mounted between two ceramic plates which in turn are attached to heat-conducting metal. If the metals are exposed to different temperatures, a voltage arises, sufficient to drive, for example, a slightly rotating motor. The thermogenerator can also be run in the other direction, ie. a voltage is connected and a temperature difference is obtained across the metal legs.

Supplier: 3B Scientific

Highly evacuated electron tube for determining the wavelength of electrons as a function of the anode voltage from the radii of the diffraction rings and the distance between the lattice planes of graphite (Debye-Scherrer-diffraction) and rendered visible on a fluorescent screen. Also intended for determining the wavelengths of monochromatic radiation at different anode voltages from the radii of the diffraction rings and the lattice plane spacing of graphite, as well as confirming de Broglie’s hypothesis.
