Microwaves can be used to warm up many items, EXCEPT...
What is ANYTHING METAL!!
Explain the process
What is: Electricity creates magnetism?
When the switch is closed, what will happen?
What is a "buzzer noise is made"?
Stops electrons from flowing easily
What is an insulator
You can remove electrons from one object and transfer them to another object by...
What is: Rubbing it (usually with wool)
When you are in the swimming pool, this behaviour is extremely dangerous
What is having electricity in/near the water
Demonstrates this conclusion
What is...electricity creates magnetism
These bulbs are lined up in what way?
What is parallel circuit
Allows electrons to flow easily
What is a conductor
If two objects have the same charge, they wil interact together how?
What is repell
You should not be standing on this when powerlines are down
A compass can show how electricity and magnetism are related. Explain how
Electricity creates magnetism and you can see magnetism with a compass
What is a cell
Examples are chalk, wood and wool
What are insulators
If two objects have different charges, how will they interact
What is: attract each other
You do NOT put this type of material into an outlet
What is anything that conducts electricity
The process of what is happening here (explain)
What is: electromagnets (electricity creates magnets)
If only one bulb was present in this diagram, would it be: brighter/the same amount of brightness or dimmer than having the two bulbs present?
What is brighter
Examples are cooper, tin foil and water
What are condutors
Rubbing a balloon on your head causes electrons to go from where to where?
From your dry hair
To the balloon
When baking a cake, if the cord falls out of the back of the mixer, your WORST idea would be to...
What is put the cord in your mouth!
How does this create electricity?
What is: a coil of wire wrapped around a magnet. When it spins, it creates electricity
If there is a break in wire A3, what componants are still able to work (if any)?
Note: assume the rectangles are light bulbs
What is: The second bulb (outside loop) will still be able to work.
If a material slows electrons down, they could be transformed into another kind of energy. Light bulbs take electricity and change it into
What is light energy
Lightning works because
What is charges build up in clouds and want to find a way to neutralize, so they "jump" to the nearest neutral (or positive) location.
