100
in the lunar cycle (an object goes around another object)
REVOLUTION
100
___________________is when light BENDS as it travels through several types of matter.
REFRACTION
100
System which allows electricity to FLOW
CLOSED CIRCUIT
100
System which will NOT allow electricity to FLOW
OPEN CIRCUIT
100
What is happening in this picture? 
EQUAL FORCES- forces that act on an object; object does NOT move
200
imaginary line about which an object rotates
AXIS
200
___________________is when light BOUNCES off matter.
REFLECTION
200
a spin, a turn is called a __________________.
ROTATION
200
What do you absolutely need to make a complete circuit?
Energy Source
Wires
Bulb(electronic appliance)
200
What tool do you use to measure force in NEWTONS.
SPRING SCALE
300
caused by Earth’s rotation, once every 24 hours
DAY and NIGHT CYCLE
300
________________ is a word that describes how light stays on matter that is dark and turns into heat.
ABSORB
300
___________ ______________ is energy that you can SEE; it travels in a straight path/interacts with matter.
LIGHT ENERGY
300
A form of ENERGY that moves through wires in a circuit
ELECTRICITY
300
Noncontact force that pulls objects to the ground
GRAVITY
400
phases caused by Moon’s revolution around the Earth, once every month
LUNAR CYCLE
400
_________________ is a word that describes how light travels through matter that is clear.
TRANSPARENT
400
KING KONGS THUMB was an example of this type of light behavior
REFRACTION
400
Type of circuit that has MANY (PLENTY) closed paths for electricity to flow
PARALLEL
400
A force between surfaces that slows objects or stops them from moving.
FRICTION
500
caused by Earth’s tilt and revolution around the Sun, once every 365 days/1 year
SEASONS CYCLE
500
describes matter that lets only some light go through
TRANSLUCENT
500
the one condition in your experiment that you CHANGE, the condition that is DIFFERENT
VARIABLE
500
Type of circuit which has only ONE, SINGLE closed path for electricity to flow
SERIES CIRCUIT
500
What is happening in this picture? Look at the arrows for assistance. 
UNEQUAL FORCES - forces that cause an object to move
