200
what color of shirt will be more comfortable during the summer
any light color shirt
300
What form of energy is air vibration and we can hear
Sound Energy
300
What is made by passing an electric current through a wire that is wrapped around a metal object such as a nail and connected to a battery
Electromagnet
300
What is only one path for electrons to travel through. If one lightbulb burns out the others turn off
series circuit
300
How do light rays travel
straight line
300
List some conductors
any object that has copper, steel or iron will be good conductors
400
What form of energy is the transfer of heat
Thermal Energy
400
What is a closed path through which electricity travels
Circuit
400
What is when each lightbulb is on a separate path. If one lightbulb burns out, the others stay on.
parallel circuit
400
What is transparent, translucent and opaque
transparent=clear and see through translucent= light filter and object looks cloudy opaque=no light can pass through and it creates a shadow
400
Students heated a beaker of water on a hot plate. They set a plastic spoon and a metal spoon in the water. After a few minutes the plastic spoon was warm but the metal spoon was very hot. Why was the metal spoon hotter
Because the metal spoon is a better conductor of heat than the plastic spoon
500

500
What is the flow of electric charges through a circuit
Electric Current
500
What can you do to increase the brightness on a lightbulb
add more energy source
500
Why does a pencil look bent in a glass of water
light is being refracted(bending)
