| Temperature | Kelvins |
| Celsius Scale- | based on the freezing point (0 C) and boiling point (100 C) of water. It is possible to have a negative temperature on Celsius scale. |
| Kelvin Scale- | based on molecular motion. Is the SI scale for temperature. The zero point on the Kelvin scale is absolute zero. The theoretical point were all motion stops. One K degree equals one C degree. No negatives in Kelvin! |
| Scientific Notion | Always multiply the coefficients and add the exponents. To divide, divide the coefficients then subtract the exponents. |
| Density- | The measure of compactness of space. D= m/v |
| How to calculate Mass, Volume, and Density | Use the triangle and cover up what you need to find. (dmv) M D V |
| Weight vs. Mass | Weight is a measure of the pull of gravity on a mass. Mass is a measure of the amount of matter in a substance or object. |
| Precision vs. Accuracy | Precision is a measure of how close a set of measurements are to one another; Accuracy is a measure of how close a measurement is to the true value of a measurement. |
| Sig Figs | Exact numbers have UNLIMITED sig figs; either counting of defined |
