What is static electricity?

Back

Static electricity is the build-up of electric charge on the surface of objects, often caused by friction. It can cause objects to attract or repel each other.

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the energy that is generated and measured by heat.

What makes a strong electromagnet?

Back

A strong electromagnet is made by wrapping more wire coils around a nail and using a stronger battery.

What is a magnetic field?

Back

A magnetic field is the area around a magnet where magnetic forces can be felt. It is represented by the pattern formed by iron filings around a magnet.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily, such as metals like copper and aluminum.

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily, such as rubber or glass.

What is an example of static electricity in everyday life?

Back

An example of static electricity is when you rub a balloon on your hair and it makes your hair stand up.

Front

How does electricity transform into thermal energy?

Back

Electricity transforms into thermal energy when it passes through a resistor, generating heat, like in a toaster.

What is the role of a battery in an electric circuit?

Back

A battery provides the electrical energy needed to power the circuit.

What happens when you increase the number of wire coils in an electromagnet?

Back

Increasing the number of wire coils around a nail increases the strength of the electromagnet.
