1. A ----------- variable is the factor being measured in an experiment, which changes in response to the ----------- variable.
A dependent variable is the factor being measured in an experiment, which changes in response to the independent variable.

• The two variables that you're recording are different, in that one variable is dependent upon the other.
• Since the height of the plant changes due to the passage of time, we say that height is dependent on time. So in this case, height is called the dependent variable.
2. ON A TABLE WHERE ARE THE DEPENDENT AND INDEPENDENT VARIABLES LISTED?
In tables, the independent variable is usually listed in the first column and the dependent variable is listed to the right.
3. DEFINE INDEPENDENT VARIABLE
It is the factor that is considered to be constant during an experiment, which affects the dependent variable.
4. ON A LINE GRAPH WHAT DOES THE HORIZONTAL AXIS REPRESENT?
INDEPENDENT VARIABLE.
5. ATOMIC NUMBER REFERS TO WHAT?
THE AMOUNT OF PROTONS IN AN ELEMENT
6. ON THE PERIODIC TABLE THE GROUP NUMBER REFERS TO WHAT?
IT CORRESPONDS TO THE NUMBER OF VALENCE ELECTRONS.

GROUPS 1,2 AND 13-18.

7. LIST THE 3 TYPES OF BONDING BETWEEN ELEMENTS VIA electronegativity
8. DEFINE POLAR COVALENT BOND.
ELEMENTS SHARE ELECTRON BUT THE ELECTRON WILL SPEND MORE TIME WITH ONE THEN THE OTHER.

9. WATER IS POLAR COVALENT. WHERE ARE THE CHARGES?
• THE NEGATIVE MEANS THAT THE ELECTRON WILL BE MORE WITH THE OXYGEN THAN THEN HYDROGEN.
10. DEFINE INTRA AND INTER
11. DEFINE HYDROGEN BONDING
12. DEFINE SOULTION
A MIXTURE IN WHICH ONE SUBSTANCE IS DISSOLVED IN ANOTHER.
13. T OR F
CAN A HYDROPHOBIC MOLECULE BE DISSOLVED BY A NON-POLAR SOLVENT?
TRUE.

IT CAN FORM HYDROGEN BONDS WITH THE WATER BUT IT CAN WITH A NON-POLAR SOLVENT, LIKE OIL.
14. DEFINE ACID AND BASE
• ACID 0-7    BASE 7-14
• -LOG10 [H+]

15. DEFINE THEORY
well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method, and repeatedly confirmed through observation and experimentation.

As with most (if not all) forms of scientific knowledge, scientific theories are inductive — that is, they seek to supply strong evidence for but not absolute proof of the truth of the conclusion—and they aim for predictive and explanatory force.

Typically, before a scientific theory can be created, a hypothesis must be developed
