Which of the following steps would not allow the bulb to produce
light?
A. Switching the wires
B. Flip the battery
upside down
C. Cutting one wire
D. Replace the wires with foil
Page 4
C. Cutting one wire
It would create an incomplete (open) circuit.
Page 5
Which of the following uses mechanical energy?
A.
D.
C.
B.
Page 6
C.
Because the toy will move and has moving parts.
Page 7
What types of energy can be seen in the following picture?
Page 8
Electricity
Light
Heat
Page 9
Which tool could NOT be used to complete the circuit and make the
bulb light up?
Page 10
The milk carton because paper is a insulator and will not let the energy
flow through
Page 11
Which picture below shows an example of electrical energy
transferring into light energy?
Page 12
The TV uses electricity to turn on and once the TV is on it creates light that
can be seen.

What force is the following picture an example of?
Page 14
A PushThe girl will push the ball
with her foot.
Page 15
What force is the following picture an example of?
Page 16
A PullThe men are being pulled down to the
ground.
Page 17
A fork falls off a table. What causes the fork to hit the floor?
Page 18
Gravity
Gravity is a force that pulls objects down.

400 g
200 g
A.
D.C.
B.
Which box will need the most force applied to it to make it move
1 meter?
300 g
100 g
Page 20
400 gD.
Even though it is the smallest box, it has the most mass and will require the most force to
move it.(Think bowling ball vs beach ball.)
Page 21
What caused the car to travel differnet distances?
Page 22
Friction
The tile has the smoothest surface and will have less friction than a rough surface, so it will let the
car travel the farthest.
Page 23
What type of force would the pick below display?
Page 24
A pull-the magnets would pull
towards each other.
Page 25
What is the drop of water doing to the light?
Page 26
The water is REFRACTING the light
Page 27
Which of the following lines in the diagram shows a refraction?
Page 28
Line D-because the line changes as it goes
through the material.
Page 29
Based on the table which cup is the best insulator?
Cup A B C D
Beginning temperature 15˚C 15˚C 15˚C 15˚C
Temperature after 5 minutes 18˚C 24˚C 26˚C 25˚C
Page 30
Cup A-because it caused the LEAST
amount of change in temperature.

Which piece of the picture below should be an insulator and which
should be a conductor?
Page 32
Insulators
Conductor
Page 33
Which of the following is a complete circuit?
Page 34
The energy can make it to every part of the circuit.
