Open Vs. Closed Circuits
What type of circuit has a break in its path?
Open Circuit
What materials do you need to build a simple circuit.
Battery, Wires, Light bulb
What is the flow of electricity through a circuit?
Electrical Current
Rubber is a ________.
Insulator
I will pick one person from your team to pick a ball of their choice. If they can bounce it in the bucket with two tries, your team will get the points.
Get points if they can get it in the bucket.
If a light bulb is lighting up in a circuit, is the circuit open or closed?
Closed
What provides energy to a simple circuit?
a battery
What is an object or piece of equipment made to do a specific job?
a device
Metal is a __________.
Conductor
Name two devices that NEED electricity.
Examples- flashlight, fridge, lamp, etc
Your light bulb is not lighting up because there is a gap between two wires. What type of circuit is it, and how could you fix it?
open, connect the wires
What can you use to open and close a circuit?
A switch
What are lines that will never intersect?
parallel lines
Ms. Batjiaka is building a circuit. To close the circuit, she used a freshly baked cookie. Is the lightbulb going to light up? Why?
No, because a cookie is not a good conductor.
Name two devices that GENERATE electricity.
hand generator, solar panels
If the wires are all connected securely to the light bulb and battery, what do we have?
A closed circuit
Kaidden, Camdyn, and Keegan are putting together a circuit. They have all of their materials set up and put together, but their lightbulb is not lighting up. What should they do first? a) freak out b) throw the batteries out the window. c) check all of their connections and test the battery to make sure it works. d) go home and bake Mr. McSnackell cookies
c) check all of their connections and test the battery to make sure it works
What is a material that allows electricity to flow easily called?
Conductor
Mr. McWisdom is building a circuit. He uses a washer to close his circuit. Is the lightbulb going to light up? Why?
Yes, because a washer is a good conductor.
Two of you will face off against me in an intense rock paper scissors battle. If at least one of you win, your team will get the points.
Points given if you can beat me!
A wire becomes disconnected from the battery. What happens to the circuit, and why?
It becomes open, so the complete path is broken and current cannot flow.
I will choose two people from your group up to build a simple circuit.
Earn points if completed correctly!
What is the word we have used in science that means to produce or make something.
Generate
If you were testing materials for a circuit, which would be more likely to complete the circuit: a metal paper clip or a plastic water bottle? Why?
A paper clip would complete the circuit because metal is a conductor and plastic is an insulator.
How do you spell my name?
