Find the solution


This LES allows the student to understand the concepts related to the properties of solutions as well as to electrical engineering. First, an scientific investigation process will lead the student to prepare an antiseptic solution with a given concentration. Next, a design process will allow the student to perfect a non-contact solution dispenser, controlled by an electric circuit. The following techniques are broached: preparing a solution, using an instrument of measurement, diagramming, assembly and disassembly.
