All About Variables
This type of variable is what we purposefully change in an experiment
Independent Variable
The three phases of matter
solids, liquids, and gasses
Water in the gas form
water vapor
The smallest piece of a substance/matter
particle
Energy has the ability to cause a change in this
Matter
This type variable is what we keep the same in an experiment
Constant Variable
The two properties that all matter must have in order for it to be defined as matter
Mass and Volume
When liquid turns into a gas
Evaporation
This type of system is where particles cannot enter or exit
Closed System
Light that is not reflected or transmitted
Absorbed
The number of things you can change in a good, fair test
1
Tightly packed particles form this phase of matter
solid
This is where condensation comes from
Air (water vapor particles in the air)
When the temperature is hotter, particles will travel ...
faster
This type of energy is the energy of movement
Kinetic Energy
This type of variable is what you measure in an experiment
Dependent Variable
This phase of matter has a definite volume but not a definite shape
liquid
100 degrees in this unit of temperature causes water to boil (evaporate)
Celsius
The three different ways to draw particle energy/movement
TRAIL LINES (longer trail lines = more energy), ARROWS (longer arrows = more energy), MOVEMENT LINEs (three lines = more energy)
The temperature of a liquid is not affected when light is _________
Reflected
The number of constant variables you can have in an experiment
unlimited!
Which of the following is not matter: Water Bottle, Helium, Coca-Cola, Balloon, Temperature, Marker, Air, Syrup, Blow Dryer, Glue.
Temperature
Droplets forming on a mirror after a hot shower or dew on morning grass is an example of this
This is what happens when particles collide with each other (think in terms of energy)
Transfer Energy
The two things that can impact a sample's total kinetic energy
Temperature and number of particles
