All parts are separate; use only the parts needed for each situation.
Just place the parts directly on the whiteboard when teaching.
This demonstration model, based on Bohr's theory of atomic structure, makes science teaching and learning easier and more enjoyable.
At last, the perfect, magnetic demonstration tool for the science classroom that helps teachers present the abstract concepts of atomic structure, isotopes and ions, in an easy and concrete way, giving students a good visual idea of the concepts involved.
All parts, except for the storing board, are magnetic; the electron shells, the two nuclei and the subatomic particles.
When not in use, the components can be kept on the storing board, which has two holes for possible hanging; one in each top corner.
Each kit includes:
2 atomic nuclei, 180 and 130 mm in diameter; 8 electron shells (use up to 4 shells for each nucleus); 20 protons; 20 neutrons; 20 electrons; 1 metal board for storing parts when not in use, 550 x 550 mm.
