2 Question Column 1-100 Materials that allow thermal or electrical energy to easily pass through them are called _______________

3 Answer Column 1-100 Conductors

4 Question Column 1-200 Conduction is energy transfer because two objects are ______________.

5 Answer Column 1-200 Touching

6 Question Column 1-300 Materials that do not allow thermal energy to pass through them easily are called _______________.

7 Answer Column 1-300 Insulators

8 Question Column 1-400 Identify the type of energy transfer that that occurs when my feet get burned when I walk across the sandy beach. Explain how the energy was transferred.

9 Answer Column 1-400 Conduction Thermal energy transferred from the hot sand to my feet.

10 Question Column 1-500 Which of the following items would you predict to be conductors – eraser, spoon, silver earring, popsicle stick, battery.

11 Answer Column 1-500 spoon silver earring battery

12 Question Column 2-100 Is the circuit below open or closed? How do you know?

13 Answer Column 2-100 Open

14 Question Column 2-200 A device that can open or close a circuit by lifting the arm is called a…

15 Answer Column 2-200 Switch

16 Question Column 2-300 How many paths, or loops, of current does a parallel circuit have? a.One b.More than one c.None

17 Answer Column 2-300 B More than one

18 Question Column 2-400 What happens to the other lights when you turn off a light in a series circuit and why?

19 Answer Column 2-400 The other lights turn off because there is only one path for the electric current so the circuit is now open.

20 Question Column 2-500 What happens to the brightness of the bulbs in a series circuit when you add another bulb and why?

21 Answer Column 2-500 The bulbs become dimmer because they share the energy from the battery since there is only one path of current

22 Question Column 3-100 Define temperature?

23 Answer Column 3-100 How hot or cold something is OR The measure of thermal energy something has

24 Question Column 3-200 What tool do scientists use to measure temperature? a.Barometer b.Anemometer c.Telescope d.thermometer

25 Answer Column 3-200 D Thermometer

26 Question Column 3-300 How does the thermal energy transfer between hot chocolate and a marshmallow?

27 Answer Column 3-300 Thermal energy transfers from the hot chocolate to the marshmallow.

28 Question Column 3-400 What happens to the motion of molecules in a pan as the pan gains thermal energy? a.The molecules’ movement does not change. b.The molecules’ movement gets faster. c.The molecules’ movement gets slower. d.The molecules’ movement stops.

29 Answer Column 3-400 B The molecules’ movement gets faster.

30 Question Column 3-500 Using words and arrows, show the heat energy transfer from hot chocolate to your hand which is holding the cup. _____ (arrow) _____(arrow) _______

31 Answer Column 3-500 Hot chocolate cup hand

32 Question Column 4-100 Identify the type of energy found in a battery.

41 Answer Column 4-500 Chemical energy electrical energy electromagnetic energy sound energy

42 Question Column 5-100 I have only one path for the electric current to travel.

43 Answer Column 5-100 Series Circuit

44 Question Column 5-200 If one light burns out, the other lights will stay lit.

45 Answer Column 5-200 Parallel circuit

46 Question Column 5-300 When another battery is added, the bulb gets brighter.

47 Answer Column 5-300 Series Circuit

48 Question Column 5-400 If I plug in my holiday lights, and I notice two bulbs do not work, they must be wired in this type of circuit.
