Question Column Which of the following items would you predict to be conductors – eraser, spoon, silver earring, popsicle stick, battery.
Answer Column Spoon, silver earring, battery
Question Column For a light bulb to work, the circuit must be ______________.
Answer Column Closed
Question Column A device that can open or close a circuit by lifting the arm is called a
Answer Column Switch
Question Column Define a parallel circuit.
Answer Column Each device has its own path.
Question Column What happens to the other lights when you turn off a light in a series circuit and why?
Answer Column The other lights turn off because there is only one path for the electric current so the circuit is now open.
Question Column What happens to the brightness of the bulbs in a series circuit when you add another bulb and why?
Answer Column The bulbs become dimmer because they share the energy from the battery.
Question Column What is temperature?
Answer Column How hot or cold something is
Question Column What tool do scientists use to measure temperature?
Answer Column Thermometer
Question Column How does the heat energy move between hot chocolate and a marshmallow?
Answer Column The heat energy goes from the hot chocolate to the marshmallow.
Question Column Name a safety precaution when dealing with heat energy.
Answer Column Use oven mitts, wear safety goggles, wear a lab coat, don’t touch hot water, etc.
Question Column Using words and arrows, show the heat energy transfer from hot chocolate to your hand which is holding the cup.
Answer Column Hot chocolate cup hand
Question Column Identify the type of energy found in a battery.
Answer Column Chemical
Question Column Identify the type of energy when electrons are in motion.
Answer Column Electrical energy
Question Column List the energy transformation that takes place in the simple circuits we created in class.
Answer Column Chemical energy to electrical energy to thermal energy to light energy.
Question Column Using words and arrows, show the energy transformation that occurs when I turn on my Ipod.
Answer Column Chemical energy electrical energy sound energy
Question Column Using words and arrows, trace the energy transformation in our circuit with the buzzer.
Answer Column Chemical energy electrical energy electromagnetic energy sound energy
Question Column I have only one path for the electric current to travel.
Answer Column Series Circuit
Question Column If one light burns out, the other lights will stay lit.
Answer Column Parallel circuit
Question Column When another bulb is added, they each become dimmer.
Answer Column Series Circuit
Question Column If I plug in my Christmas tree lights, and I notice two do not work, they must be strung in this type of circuit.
