| A | B |
|---|
| hypothesis | idea or guess used to solved a problem |
| physical science | the study of matter and energy |
| independent variable | a factor that is changed or adjusted by the experimenter |
| experiment | an organized process to gather observations for testing a hypothesis |
| dependent variable | a factor that changes due to a change in the independent variable |
| control setup | a standard for comparison - ensures the experimental results is due to the condition tested |
| constant | factor does not change in an experiment |
| kilograms | unit measurement of mass |
| meter | unit of length |
| mass | amount of matter in an object |
| volume | amount of space occupied by an object |
| meniscus | curved surface of liquid |
| centi | 100 |
| independent variable | the variable place on the horizontal axis (x) |
| graduated cyclinder | measures liquid volume |
| goal of science | to understand the world around us |
| meter stick | measures length in the lab |
| dependent variable | placed on the vertical axis (y) |
| density | mass/volume |
| volume | mass/density |
| mass | density times volume |
| gravity | every object that exerts a force on other objects |
| weight | pull exerted by Earth on objects |
| inertia | resists change in its state of motion |
| mass | will not vary in a specific object |
| increase the force of attraction between two objects | by bringing them together |
| grams | measures density |
| grams/mL | density of water |
| milliter | liquid volume |
| weight | is measured in newtons |
| objects that float | has a density < 1 g/mL |
