The document discusses modeling electric circuits and current flow. It explains how to represent current as the flow of charge through a circuit using models like moped riders carrying pizzas. It also describes using a water circuit model and electrical circuit symbols. Students are asked to design their own circuit with a switch and draw it using the proper symbols. An exit ticket asks students to list things they want to practice, expect on a test, and enjoyed from the lesson.

2. Explain why one bulb is lit and the others are not:

3. What do the pizza shop and the house of party-goers represent? In this model, the moped riders represent the flow of charge and the pizzas represent the electrical energy carried around the circuit. How can we model electric circuits?

4. Water model of a circuit
