Building and Identifying Closed Circuits
Grade 6 Science Understanding how electricity flows Learning to build simple circuits
What is an Electric Circuit?
A path for electricity to flow Must have a power source (battery) Needs conductors (wires) to carry electricity Requires a load (light bulb, motor, etc.)
Closed vs. Open Circuits
{"left":"Complete path for electricity\nCurrent can flow freely\nLight bulb will turn ON\nAll connections are secure","right":"Broken or incomplete path\nCurrent cannot flow\nLight bulb will stay OFF\nGap or loose connection present"}
Circuit Building Challenge
Work in pairs to build a simple circuit Use: 1 battery, 2 wires, 1 LED bulb Connect the components to make the bulb light up Try disconnecting one wire - what happens? Record your observations in your science journal
Circuit Detective
Look at each circuit diagram Decide: Is it CLOSED or OPEN? Explain your reasoning What would happen to the light bulb in each case?
Key Takeaways
Closed circuits have a complete path for electricity Open circuits have breaks that stop electrical flow All components must be properly connected Switches can open and close circuits We can identify circuit types by checking for gaps or breaks
