Experiment Set Magnet and Compass

From dancing snakes over the garage to floating compass needles, the experiments in this case will stimulate children to have fun engaging with the phenomenon of magnetism and understanding how a compass works.

There are plenty of links with the children's own familiar world to stimulate their interest. The experiments train children to make precise observations, draw conclusions and apply their findings, e.g. to construct their own magnet or to find the north pole on unlabelled magnets.

Almost "incidentally", material knowledge can be imparted at the same time, e.g. the names of different metals.

The materials provided in the case offer a variety of child-friendly experiments and tests on the related topics of magnets and the compass. The individual steps can be done in groups or at a single workstation.
The set contains materials for up to 15 groups and experiments for 24 workstations, including corresponding copy templates. A teacher's guide contains instructions for all the steps.

All the materials are supplied in a plastic case where everything has its fixed place in the foam insert. This makes it easy to check everything is there and the individual components won't fall around during transport.
An illustrated overview provides a good summary of where each piece belongs and can be quickly removed and replaced thanks to the hook and loop fastening.
