## Independent Variable
The independent variable in an experiment is variable being manipulated by the experimenter.
## Dependent Variable
The dependent variable in an experiment is the variable being measured by the experimenter.
## Standardized Variable
Standardized variables in an experiment are the variables that are held constant.
## Control Group
The baseline (default case) for the independent variable.
## Experimental Group
The set of all tests where the independent variable is changed.
## Hypothesis
An educated prediction about how changing the independent variable will affect the dependent variable.
## Qualitative
Measurements or observations that are strictly descriptive or categorical in nature and do not include numerical information.
## Quantitative
Measurements or observations that include numerical information.
## Inference
Using trends to make predictions.
## Observation
Any measurement qualitative or quantitative in nature.

### Solution
A solution is the result of one or more solutes dissolving into a solvent. For example, salt can be dissolved into water to create a salt water solution.
### Solute
A solute is a compound that can be dissolved. For example, in salt water, salt is the solute.
### Solvent
A solvent is a compound that can dissolve other compounds. For example, in salt water, water is the solvent.
### Hydrogen bonds
Hydrogen bonds are a type of weak inter-molecular bond that occurs in polar molecules, where the hydrogen has a slight positive charge.
### Hydrophilic
A type of material that water is attracted (sticks) to.
### Hydrophobic
A type of material that repells water.
### Acid
A compound with a low pH (<7 at standard temperature) that has a high concentration of hydrogen ions (H$^+$).
### Base
A compound with a high pH (>7 at standard temperature) that has a low concentration of hydrogen ions (H$^+$).
### pH
The pH is a logarithmic scale that measures the acidity or basicity of a compound. The lower the pH, the more acidic. The higher the pH, the more basic.
### Buffer
A substance that resists change in pH.
