The Secret Boxes let your pupils discover independently how a "secret" circuit is made. By experimenting with the push button, unscrewing a bulb or using, for example, alternating current (Secret Boxes Electronics) instead of direct current, your pupils can find out how the circuit in the Secret Box is made. All components used are visible at the top of the Secret Box. Ideal for classroom use in a rotational practical class, e.g. with 4 sets for 32 students.
Two sets are available, the Secret Boxes Basic and the Secret Boxes Electronics.
Secret Boxes Electronics
This set of 8 Secret Boxes works with LEDs, resistors, LDR resistor, transistor, capacitor and push buttons. The student should be familiar with the concepts of circuit, series and parallel connection and the operation of resistors, LDR resistor, LEDs, transistor and capacitor. These Secret Boxes are also numbered from 1 to 8 and increase in difficulty. Connect to a DC voltage or AC voltage of 10 -15 volts. Both types of voltage are needed for research. Comes complete with solutions in diagram form for the teacher.
