  • Page 19 Project #9 Light the Way Educational Corner: What is really happening here? 1. The batteries (B3) convert chemical energy into electrical energy and “push” it through the circuit, just like the electricity from your power company. A battery pushes electricity through a circuit just like a pump pushes water through a pipe.
  • Page 20 Project #10 Flip It Educational Corner: The slide and press switches included in The “on” position of a switch is also called Snaptricity ® are simple switches, more the “closed” position. Similarly, the “off” complex types are also available. position is also called the “open” position. Switches come in almost every shape This is because the symbol for a slide and size imaginable.
