Term
| Dependent vs Independent Variable |
|
Definition
Independent variable is something we can control and what we change each time in an experiment. Dependent variable is the outcome and something we can't change. Independent = input
dependent = output |
|
|
Term
| Quantitative vs Qualitative |
|
Definition
Qualitative deals with descriptions and words (example; the drink is a light blue with foam on top)
Quantitative deals with numbers and facts (example; the drink is 87 degrees fahrenheit and is 16 ounces) |
|
|
Term
|
Definition
| Control group is when your doing an experiment it's the group without an independent variable. (example; an experiment testing if more people can taste red or blue food coloring in their water, the control group would just have plain water) |

|
Term
|
Definition
| chemical bond where hydrogen atom of one molecule is attracted to an electronegative atom (usually FNO) of another molecule |
|
|
Term
|
Definition
| When you drop water on a penny it forms a dome because the hydrogen bonds are so strong and because there's nothing else to bond with so it forms a "skin" or dome on top so it doesn't spill over |

|
Term
|
Definition
| when atoms of same or different elements rearrange themselves to form a new substance (usually absorbing or giving off heat in the process) |
