| the study of matter and energy and their interactions | Physical Science |
| any substance that takes up space and has mass | matter |
| 3 states of matter | solid, liquid and gas |
| a state of matter in which the substance has and keeps a definate shape and volume | solid |
| state of matter in which the substance takes the shape of its container | liquid |
| state of matter in which the substance takes both the shape and volume of its container | gas |
| amount of matter an object has | mass |
| amount of space the object takes up | volume |
| can be measured using balances scales, measuring cups, graduated cylinders and rulers | mass and volume |
| size, shape, color, texture hardness and odor | all properties of matter |
| has many different forms such as light, heat, sound, electrical and mechanical | energy |
| a form of energy used by plants to live and that we use to see things | light |
| light travels in a ______________ until it strikes an object or travels through other matter | straight line |
| energy can cause | motion or create change |
| light can be | reflected, refracted or absorbed |
| a light wave bounced back from a surface | reflection |
| a reflection on a polished surface will have | right and left reversed |
| the bending of light rays as they move from one material into another material | regraction |
| to take in or soak up | absorb |
| when light is absorbed it is retained and not | reflected or refracted |
| when things give off light they also give off | heat |
| heat can be procudes through | friction |
| the process of becoming a vapor | evaporation |
| the process of changing from a gas to a liquid | condensation |
