Science Vocabulary Flashcards
System
A set of parts that work together (interact) toward a goal or outcome.
Evaporation
The process where water slowly changes from a liquid to a gas and single molecules of water leave the surface to go into the air at one time
Model
A representation we use to understand or describe a phenomenon
Independent variable
A variable that is changed
Dependent Variable
A variable that is affected by the change
Open System
Matter can get in and out of it though opening in the system
Closed System
No matter can get or out of the system
Condensation
The process in which water is it’s gaseous form is changed into liquid water
transparent
A material that allows light to pass through so that objects behind can be seen
Opaque
A material that does not allow light to pass through, not transparent
Reflected Light
When light bounces off an object
Kinetic Energy
The energy of movement
Temperature
The measure of average kinetic energy of particles in a substance
Thermal Energy
The motion of particles in a substance
Heat
A transfer of energy from warmer substances to colder substances
Transmitted Light
When light goes through an object
Criteria
The requirements of our design needs to meet and to be considered successful
constraints
The things we can and can’t do ( the limits that we will set on our design)
Absorption
When light transfers energy into particles
Conduction
When thermal energy is transferred via particle collisions
Variable
Things about a system that we can change
Mean
The average of a set of numbers
Molecules
Particles that are too small to see with an unaided eye (make up gases and liquids)
Control Variable
A variable that is kept the same
Styrene/ Styrofoam
A porous material that is used in many objects
Porous

Vacuum Insulated
A container that has a vacuum between the outer layer and the inner layer
Air Insulated
A container that has an inner and outer wall with air in between
