After a slight rearrangement of lab groups due to a dead voltmeter, the students explored current and circuits. One of our groups decided they wanted to see if they could make the bulb burn brighter, and hypothesized that adding additional batteries could make it brighter. In order to test the level of light, they added a switch to control the flow of current. When students ask to explore based off of an experience with a more directed lab, that's a great opportunity to extend learning!
