This is the perfect kit to get your kids started with basic electricity! It includes everything you need to jump into conversations about circuits (series/parallel), loads, voltage, current, switches etc. Teach the students how to make their own circuit switches using brass fasteners and paper clips. The kit includes 3 different loads - DC motor, Buzzer and light bulbs so they can tinker with different options. This is a great, self-contained kit to send home to virtual students or distribute to students during in-class learning. Students can twist connect the wire to each load and battery holder - no soldering required. **2 x 2AA holder may be substituted to 4 x 1xAA holders based on inventory**
