- Two (2) Wires
- Batteries Block
- Lightbulb Block
Imagine a path. Imagine traveling along that path to get somewhere. Imagine traveling along a different path to return to where you started. We travel along paths in many different ways: people walk through a hallway or up the stairs; cars drive on roads; water travels down a river and through our plumbing.
Using two wires, make a pathway from the Batteries Block to your Lightbulb Block and back to the Batteries Block as in the drawing. What happens? Can you try another way? Another way? Now, can you get the light to go on without using the wires? How did you do it? What is the same/different when you use the wires or don't use the wires? Why?
Electricity is flowing from the positive side of the batteries, through the wire, through the light, and then through the other wire back to negative side of the Batteries Block. Trace the pathway with your fingers. Draw the component blocks and wires. Look carefully and be precise in your drawing. When you are finished, trace the pathway electricity travels in your drawing. Notice if it is the same as the pathway you created with your actual Circuit Blocks components.
Electrical energy can be stored in batteries. Electricity travels when it has a closed pathway through which to move. A closed pathway where electricity flows is called a circuit. In these explorations, when you make a circuit, it will always have only one Batteries Block, and at least one HAPPEN Component Block, such as a Lightbulb, an LED or a Motor. Please make sure to stay inside the parameter of only using one Batteries Block in each circuit.
