Why are electrical wires covered in plastic?
Plastic is a good insulator so you won't get shocked.
What is the area around a magnet where the magnet's force reaches called?
Magnetic Field
We tested various materials like popsicle sticks, yarn, paperclips, foil and wire mesh in this experiment.
What is testing items to be conductor and insulator?
Materials you should never stick in a plug in.
What are conductors (such as metal)?
When we created a _________________ circuit using conductors, the light bulb lit up.
Closed
Electrons from the hair build on a hat so your hair stands up because it is positively charged. This is called _______________________.
Static Electricity
This was the independent variable in our circuit building experiment.
The different materials used in the circuit
You should not carry one of these during a storm.
What is an umbrella?
What type of energy transformation takes place in an oven?
Electrical to thermal
We used symbols to show this in our insulator and conductor experiment.
A circuit
You should not do this outdoor summer activity at the beach during a storm.
What is swim or take a boat ride?
This can increase the strength of an electromagnet made with a battery, wire and iron nail.
Wrap more wire coils around the nail
A large discharge of static electricity seen during storms.
What is lightning?
This was the dependent variable in our insulator/conductor experiment.
The light bulb lighting up
An electrical component which slows electron flow.
What is a resistor?
