For this activity, you must follow along the teacher's instructions and build a circuit in charge of lighting up an LED and controlling it with a pushbutton. Then, you must upload a short video of no more thant ONE (1) minute to this activity, saying both your names, showing the circuit working and answering the following questions: 1. ¿How does current flow through the circuit? 2. ¿Where do electrons have the highest voltage, at the beginning of the circuit or at the end of it? 3. ¿What could we replace the pushbutton with so that the circuit keeps working in a similiar way, if not the same way?
