Atomic Demonstration Simulation

This item is designed to demonstrate the stabilizing effect of neutrons on the atomic nucleus. The ""protons"" are made of disc magnets while the ""neutrons"" are made of browned iron discs. The ""protons"" will, because they are magnetized, repel one another when placed on flat surface or overhead projector. The stabilizing effect of the ""neutrons"" is illustrated by placing them between the ""protons"", thereby eliminating the repulsive force. The ""protons"" are supplied with red marking, the ""neutrons"" with blue. Supplied as single pieces. The “neutron” can be ordered under product code MO150905.

Chain Reaction Apparatus, spare pins only.

This pack of 500 x 10 mm plastic cubes is used to investigate and demonstrate half-life. Each cube has one black face, the other faces all being yellow. The cubes are thrown or scattered like dice and those which land with the black face uppermost represent radioactive nuclei which have decayed. The black upward facing cubes are then removed, the remaining cubes thrown again and the process repeated. The removed cubes represent radioactive decay and decay curve can be plotted from the results.

A low cost apparatus for the demonstration of Rutherford scattering by means of gravitational analog of inverse square law repulsion. Comprises wooden launching ramp with guiding groove running down its curved front face along its length and index marks at 40, 60, 80 and 100 mm height above the base, that provides pre-determined launching heights. Also included is spun aluminium hill along with 19mm diameter steel ball. The shape of the aluminium hill has been carefully determined by varying its height above the base line by an amount arrived on the basis of the reciprocal of the radius. Ramp Dimensions (L x W x H): 300 x 50 x 105 mm. Hill Dimensions (Dia. x H): 280 x 60mm.
