What's all the buzz about electricity? Scholars take part in a scientific activity to test the conductivity of liquids and solutions. They first see if water, salad oil, alcohol, and vinegar cause a buzzer to buzz when electrodes are placed in each liquid, then mix in salt or sugar to see how they affect conductivity.
