Lesson/Unit Plan Template GLEs: Strand I, 2.A Objectives: Identify the four contact points on a bulb and battery circuit. Assessments: Asking the students questions as they test circuits about how the electricity behaves. Grade: 4 Materials: Batteries, wires, bulbs, the Smart-Board. Description (Connect to the 3 Principles and Design Model): Principle #1 Besides just reviewing their previous work on circuits in the Engaging Student classroom at RBE, the students’ understanding of conductors and Prior insulators will be critical to their learning of the way this circuit Understandings: works to light a bulb. The students will be asked why the Describe how electricity goes through the wires and not the air, and that kind of student prior thing. conceptions will be assessed and build upon. Principle #2 From the students’ prior work with circuits, we will move from a Essential Role of general idea of batteries lighting bulbs to the understanding of Factual Knowledge how electricity flows to do so. This will be done by having the and Conceptual students draw the wires in the ways that allowed the bulb to light, Frameworks in and then drawing the path that the electricity took to get from the Understanding: negative end of the bulb to the positive end of the bulb. To get to Characterize how this understanding, the students will have to learn about the you will build from filament in the bulb as well as the separate contacts on the side student prior and bottom of the bulb, and how those contacts are used to get conceptions toward electricity to pass through the filament. interconnected knowledge of facts and concepts. Principle #3 As the students are allowed to test the circuits for themselves, I Promoting Self- plan to move around the room, asking them specific questions Monitoring: about their results and their thinking.
