3.P.3A.2- Develop and use models to describe the path of an electric current in a complete simple circuit as it accomplishes a task (such as lighting a bulb or making a sound.

The teacher will use direct instruction to teach the class about electricity and how it works. The class will have a discussion for questions and comments. The teacher will pass out materials for the activity, where the students will work with their desk mates (which are groups of four). The teacher will hand out the students science journals, two pieces of wire, one battery, and one light bulb per group. The teacher will go over the behavioral expectations and instructions. The students are expected to figure out, using their new knowledge on closed and open circuits, to make the light bulb light up. The students will let the teacher know when they have figured it out, demonstrate it, and draw a diagram explaining the process in their science journals. The students will then answer the questions in their journal that the teacher has written on the board.

Questions the students must answer after the lesson:

• How are the wires related to the light bulb lighting up?
• Do you know another instance where knowing how to make a closed circuit may be important?
• What are some examples of electricity being used in this classroom?
• What ideas or materials can you add to this experiment to make it more complex and make the light bulb light up? Are there materials that you can put in between the wires, and the electric current still go through?
