Electricity & Atoms
How does a switch work on a circuit?
It opens and closes the circuit to allow the electricity to flow.
What is the most basic circuit called?
simple circuit
A material that does not allow electricity to flow through it. An example would be a rubber eraser.
Insulator
Name one way to be safe when using electricity. Explain.
Name one we discussed in class.
What two parts of the atom are in the nucleus?
Proton and Neutron
This type of circuit has one path with two lights.
Series circuit
What is a natural example of static electricity? (hint: big and sky)
Lightning
A material that allows electricity to flow through it. An example would be a paperclip
Conductor
Name two different ways to be safe while using electricity. Explain.
What is the positive part of an atom?
Protons
A circuit that has parallel pathways for electricity to flow.
parallel circuit
Is water an insulator or conductor?
Conductor.
Why should we not stick a metal fork into a toaster?
Metal is a conductor. It conducts electricity and can shock us.
What are the three main parts of an atom? Think back to our 3rd-grade model of an atom.
If a bulb was removed from this type of circuit, the other bulbs in the circuit would still work
Parallel Circuit
When we rub a balloon onto our heads, our hair sticks to the balloon. Why does our hair sick to the balloon? (Think charges)
Opposite charges attract. (One is positive, one is negative)
Name two examples of an insulator.
rubber, wood, paper, fabric
What should you do before changing a lightbulb in your home?
Turn off the lights.
Electricity is created when __________ jump from one atom to another atom. (hint: negatively charged part of the atom)
Electrons
When we created the cooper tape circuits, how many batteries did each type of circuit need to work? Simple Circuit, Series Circuit, Parallel Circuit)
Simple = 1 Battery
Series = 1 Battery
Parallel = 2 Batteries
Think back to when we hung styrofoam cups on the side of the table. When we rubbed both cups with wool, they repelled away from each other. Why did this happen?
Like charges repel. Negative charge and negative charge will cause the cups to repel.
Why are most cords and wires wrapped in rubber?
Rubber is an insulator. It insulates the electricity so we do not get shocked when we touch the wires.
Why do we stay away from lakes during a storm?
Water is a conductor. Lightning may strike there.
