Big Idea 10 and 11

Front

What is a conductor?

Back

A conductor is a material that allows electricity or heat to flow through it easily. Examples include metals like copper, aluminum, and certain liquids like saltwater.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity or heat to flow through it easily. Examples include rubber, plastic, and wood.

Front

What happens when a conductor is placed in an electrical circuit?

Back

When a conductor is placed in an electrical circuit, it allows electricity to flow, which can power devices like lightbulbs.

Front

What is energy transfer?

Back

Energy transfer is the process of moving energy from one object or system to another, such as transferring muscle energy to a ball when throwing it.

Front

What is the purpose of wearing rubber gloves while working with electricity?

Back

Rubber gloves insulate the electrician from electrical currents, preventing electric shocks.

Front

What is sound?

Back

Sound is a type of energy made by vibrations that travel through air, water, or solids.

Front

What is pitch in sound?

Back

Pitch is how high or low a sound is, determined by the frequency of the sound waves.

Front

What materials are good conductors of heat?

Back

Good conductors of heat include metals like aluminum, copper, and silver.

Front

What is the role of vibrations in producing sound?

Back

Vibrations create sound waves that travel through a medium (like air) to our ears.

Front

How does the energy of a thrown ball relate to muscle energy?

Back

When a ball is thrown, muscle energy from the arm is transferred to the ball, giving it kinetic energy to move.
