Battery technology starts with chemistry and the understanding of how unlike metals in the presence of acid can create electricity. This is a one-hour lesson in which students will be exposed to this basic technology.
In this lesson, students will learn basic concepts of battery technology. After an instructor-led discussion on battery basics, the students will use four lemons to create a simple battery. Students will work in teams of two in this instructor-led activity. They will also have a handout for reference. Students will use an LED to test their new batteries.
Students will start with two lemons to simulate a 'two-cell' battery. They will attempt to light the LED with this set-up. It won't light. They will then add two more lemons to make it a 'four-cell' battery. When this is done, the LED should light.
