All Solved Correctly.
Conductor - Answer any material that allows electricity to pass through it.
Circuit - Answer Electricity traveling in a circular path.
Three parts of circuit - Answer Source, path, load, and switch.
(battery/wall plug). (wires). (lightbulb/buzzer). (control).
Lightbulb in holder image - Answer circle with squigglie line inside
on off closed position image - Answer _-_ Electricity flowing.
1 1/2 VOLT BATTERY cylinder - Answer 1.5 -T t-
9 Volt two connect on top rectangle - Answer 9v
6 volt two places connect aat top - Answer 6 v square
110 Volt regular wall extension - Answer AC power. Plug symbol or circle with an S in the
middle
Two wires crossing - Answer wires crossing + or with a dot in middle
Fuse - Answer Too much electricity flowing can heat up and burn or melt. Big slanted S shape
with lines.
Parallel circuit - Answer Has more than one electrical path

If a car and a bowling ball fell off a 100 ft cliff at the same time, which would hit the ground
first?
A. Car
, B Ball
C. No diff - Answer C. No diff.

C. No diff - Answer C. No diff
Gravity pulls on both equally and both have the same distance before hitting ground.
Magnets - Answer They all have a south pole an a north pole. N and P they will stick. P and P
they will resist.
Spur gear - Answer Has straight teeth on the outside edge.
Driver - Answer The part of the gear that does the pushing.
Gears are made of - Answer Plastic or metal
Gear with fewer teeth - Answer Will move faster.
To get the speed - Answer divide the # of teeth on one gear by the # of teeth on the other.
Mitter gear - Answer Grooves cut at a slant. Turn horizontal or vertical.
Pulley used for - Answer will it move, or how hard will it be to move a weight using the
pulley
Parts of a pulley - Answer Block (holds the wheel). Wheel (usually has a groove in it so the
rope can go around the edge w/o falling off.
