Forms of Energy

Pitch

• Pitch refers to the loudness of a sound.

• Pitch is how high or low a sound is.

• Pitch is the duration of a sound.

• Pitch is the quality of a sound.

Insulator

• A material that allows electricity or heat to pass through easily, like metal.

• A substance that stops electricity or heat from passing through, like rubber, plastic, or wood.

• A type of conductor that enhances the flow of electricity.

• A device that generates electricity from heat.

Electrons

• Electrons are large, visible parts of an atom that help create heat.

• Electrons are tiny, invisible parts of an atom that move around and help create electricity.

• Electrons are particles that only exist in gases and do not contribute to electricity.

• Electrons are the heaviest components of an atom and are found in the nucleus.

Reflection

• Reflection occurs when light is absorbed by a surface.

• Reflection happens when light bounces off something, like when you see yourself in a mirror.

• Reflection is the process of light passing through a transparent object.

• Reflection is the bending of light as it passes from one medium to another.

Resistor

• A resistor allows electricity to flow freely without any resistance.

• A resistor slows down the flow of electricity in a circuit, like a speed bump for electric current.

• A resistor increases the voltage in a circuit.

• A resistor is used to store electrical energy.

Sound Travel

• Sound travels by moving through air, water, or solids in waves, like ripples in a pond.

• Sound travels only through air and cannot move through water or solids.

• Sound is a type of light wave that requires a medium to travel.

• Sound can travel faster in a vacuum than in any medium.

Electric Force

• Electric force is the push or pull between objects that have electric charge.

• Electric force is the gravitational pull between two masses.

• Electric force is the frictional force between two surfaces.

• Electric force is the magnetic attraction between two magnets.

Electromagnet

• A magnet that is always on

• A magnet made when electricity flows through a wire

• A permanent magnet that cannot be turned off

• A magnet that only works in cold temperatures

Radiation

• Radiation is a type of sound wave that travels through air.

• Radiation is heat that moves through space without needing anything to carry it, like the warmth from the Sun.

• Radiation is the process of transferring energy through direct contact.

• Radiation is a form of light that can only be seen with special equipment.

Lens

• A clear, curved piece of glass or plastic that helps us see better by bending light.

• A type of camera used for taking photographs.

• A device that measures temperature.

• A tool used for cutting glass.
