This fun resource can be used to demonstrate open and closed circuits as well as bringing some WOW to your science lessons.
Completely safe to use, simply touch both the contacts on each end of the stick to form a complete circuit. When a circuit is formed the Circuit Maker Breaker will emit a loud beep and the lights on the front will glow up. As soon as one of the contacts isn't touched, the circuit will be broken and the Circuit Maker Breaker will stop working.
Bring some WOW to your lesson by adding more and more people to the circuit! Get the children to form a circle linking hands so that the circuit maker breaker will light up and beep, but when the link is broken then the stick stops working. How many children can you get to complete your circuit?
Add a further challenge by allowing the children to find objects to put in the link that will break or continue the circuit for the stick to work! Or use the Circuit Maker Breaker as a tester of insulators or conductors by covering the ends of the stick with different materials and testing whether a circuit can still be created.
