In this activity, students will work with batteries, wires, and small LED lights to create a variety of circuits. This lab is designed to be broken into 3 distinct parts. Therefore, the numbering for each task restarts for each section. There are 3 tasks for Part One, 2 tasks for Part Two, and 2 tasks for Part Three.
Before participating in this lab, students should have a good understanding of electrical energy. However, Part One is designed for students who have very little knowledge of circuits – they are exploring what works and what doesn’t.
For Parts Two and Three, students should know the difference between series and parallel circuit designs.
For Part One, each group should be provided with two AA batteries (1.5V), two small LED light bulbs, several sets of wires, and at least one resistor. They may also find electrical tape handy, as they connect the bulbs, wires, and batteries together.
For Parts Two and Three, students will need additional batteries, bulbs, and wires.
To print four boxes per page, open the file using Adobe Acrobat Reader and choose the option "multiple pages" on the print screen.
This activity is a part of a unit designed to address the following Next Generation Science Standards:
· energy may take different forms (MS-PS3-5)
· the transfer of energy can be tracked as it flows through a system (MS-PS3-3)
· make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents (4-PS3-2)
· develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials (MS-PS4-2)
