| 1st step of scientific method | choose a problem |
| 2nd step of scientific method | research the problem |
| 3rd step of scientific method | develop a hypothesis |
| 4th step of scientific method | experimental design |
| 5th step of scientific method | test hypothesis |
| 6th step of scientific method | organize your data |
| 7th step of scientific method | state your conclusion |
| most important safety rule in lab | follow teacher instructions before beginning a lab |
| independent variable | what the experimenter changes in an experiment |
| dependent variable | what changes as a result of what the experimenter in the experiment |
| control in an experiment | all the other factors that have the potential to change and affect the dependent variable but shouldn't |
| plates of the earth | move about as fast as your fingernails grow |
| the basic SI unit of length | meter |
| a unit of volume | liter |
| a unit of weight | gram |
| freezing point of water | 0 degrees celcius |
| motion | the state in which one object's mass and velocity |
| reference point | a place or object used for comparison to determine if an object is in motion |
| International system of units | a system of measurement based on multiples of ten and on established measures of mass, length, and time |
| speed | the distance an object travels per unit of time |
| average speed | the overall rate of speed at which an object moves: calculated by dividing the total distance an object travels by the total time |
| instantaneous speed | the speed of an object at one instant of time |
| velocity | speed in a given direction |
| slope | the steepness of a line on a graph, equal to its vertical change divided by its horizontal change |
| plate | one of the major pieces that make up the earth's upper layer |
| theory of plate tectonics | the theory that pieces of earth's outer layer are in constant motion |
| acceleration | the rate at which velocity changes |
| kinetic energy | energy that an object has due to its motion |
| potential energy | stored energy that results from the position of shape of an object |
