Students had to put their thinking caps on today to figure out how to create a circuit that would power a buzzer and a light at the same time when the "watering trough" emptied. We constructed the trough and when it was empty, it tilted and connected to close the circuit. there was a lot of "productive struggle" going on in the lab and it was AWESOME! The hard part was figuring out how to make the light and buzzer go off at the same time! There were lots of cheers when they figured it out!
