Basic Principles
100
Also known as the "test" variable, it's what the experimenter manipulates.
What is the Independent Variable?
100
The amount of matter in a substance.
What is Mass?
100
This color of light is reflected by a red table.
What is red?
100
Particles lose or gain _________ during a phase change.
What is Energy (or Motion/Speed)?
100
The Law of Conservation of Energy states that "energy is neither ___________ or ____________."
What is Created or Destroyed?
200
Also known as the "outcome" variable, it is what the experimenter measures.
What is Dependent Variable?
200
This type of substance is made up of only ONE type of particle (element or compound)
What is Pure Substance?
200
All of the colors combined make up this.
What is White Light?
200
In which direction does Heat always flow?
What is "hotter to colder" or "from the hotter object to the colder object"?
200
This happens to the Distance between particles of a substance when they gain energy.
What is Increase?
300
A statement that leads to a scientific investigation.
What is Hypothesis?
300
Is combining water, lemon juice, and sugar a Homogeneous or Heterogeneous Mixture?
What is Homogeneous Mixture.
300
A red table reflects red light and ___________ all other colors.
What is Absorbs?
300
If a ball is currently falling, does it have BOTH Kinetic and Potential Energy?
What is Yes?
300
Where does the car have the most Potential Energy?
What is Point W?
400
The process of an investigation being copied by other scientists to collect more data.
What is replication?
400
This element has an atomic number of 1 and is a gas at room temperature.
What is Hydrogen?
400
This state of matter Sound travels fastest through.
What is Solid?
400
A flashlight transforms __________ energy (stored in batteries) into electrical and light energy.
What is Chemical energy?
400
Temperature change affects the rate of a chemical reaction by changing the ________ of the colliding particles.
What is Speed?
500
This type of graph shows the direct relationship between an independent and dependent variable, and is the go-to graph when time is involved.
What is a Line Graph?
500
How are Groups oriented on the Periodic Table and why are they also called a Family?
A Group is a vertical column. They are also called families because elements share similar properties / are chemically reactive in a similar way.
500
This light behavior occurs when light slows down as it passes from one medium into another.
What is Refraction (bending)?
500
Useable chemical energy in food first begins as what type of energy?
(Think: how energy enters the food web...)
What is Light Energy?
500
During a phase change, the energy of particles increases or decreases but the _______ always remains the same.
(Think: Law of Conservation...)
What is Mass?
