Energy Transformations
This type of energy is stored inside a battery before it is used.
What is chemical energy?
For electricity to flow, a circuit must be this, meaning there are no breaks.
What is a complete circuit?
When electricity flows through a buzzer, it produces this output.
What is sound?
Light travels in this way, which means it goes straight from one place to another.
What is a straight line?
This color of light is made when all colors mix together.
What is white?
When you turn on a flashlight, chemical energy changes first into this kind of energy.
What is electrical energy?
This part of a circuit provides the energy to make electricity flow.
What is a power source or battery?
When electricity flows through a light bulb, it produces this output.
What is light?
When light bounces off a surface like a mirror, this happens.
What is reflection?
When light reflects off a smooth surface, it creates this kind of reflection.
What is a clear or regular reflection?
After electrical energy flows through a flashlight, it changes into this kind of energy that helps you see.
What is light energy?
This part of a circuit controls the flow of electricity by turning it on or off.
What is a switch?
When electricity flows through a motor, it produces this output.
What is motion?
When light passes through water or glass and bends, this is called.
What is refraction?
When light reflects off a rough surface, it creates this kind of reflection.
What is a scattered or diffuse reflection?
When a fan is plugged in, electrical energy changes into this type of energy that makes the blades move.
What is motion energy?
These two parts must be connected to complete a circuit and allow electricity to flow.
What are wires and a power source?
When electricity flows through a heater, it produces this output.
What is thermal (heat) energy?
When light hits a black shirt and does not pass through or bounce back, this happens.
What is absorption?
This happens to light when it moves from air into water.
What is it bends or refracts?
When you rub your hands together, mechanical energy changes into this kind of energy you can feel.
What is thermal (heat) energy?
This happens if a circuit is open or broken.
What is electricity stops flowing or the circuit does not work?
Name two outputs that can happen at the same time in some circuits.
What are light and sound (or motion and heat, etc.)?
Name one thing light can do when it hits an object.
What is reflect, refract, or absorb?
This type of material lets most light pass through it without bending or blocking it.
What is transparent?
