Matter
| Term | Definition |
|---|---|
| Matter | Has mass and takes up space |
| Pure substances | Cannot be separated by physical means into simpler substances |
| Mixtures | Can be separated into components by physical means |
| Elements | The simplest form of matter; cannot be chemically separated into a simpler substance |
| Compounds | 2 or more elements, chemically combined |
| Homogeneous mixture | Mixture in which the components are uniformly distributed throughout its volume and cannot be seen separately |
| Heterogeneous mixture | Mixture in which the components are not uniformly distributed throughout its volume and can be easily seen separately. |
| Is tea a homogeneous or heterogeneous mixture? | Homogeneous mixture |
| Is ice in water a homogeneous or heterogeneous mixture? | Heterogeneous mixture |
| Is fruit juice a homogeneous or heterogeneous mixture? | Homogeneous mixture |
| Is soupy noodles a homogeneous or heterogeneous mixture? | Heterogeneous mixture |
| Is medicine a homogeneous or heterogeneous mixture? | Homogeneous mixture |
| Is assorted candies a homogeneous or heterogeneous mixture? | Heterogeneous mixture |
| Is honey a homogeneous or heterogeneous mixture? | Homogeneous mixture |
| Is assorted dry fruits a homogeneous or heterogeneous mixture? | Heterogeneous mixture |
| Is milk a homogeneous or heterogeneous mixture? | Homogeneous mixture |
| Is soil a homogeneous or heterogeneous mixture? | Heterogeneous mixture |
| Is blood a homogeneous or heterogeneous mixture? | Homogeneous mixture |
| Is oil in water a homogeneous or heterogeneous mixture? | Heterogeneous mixture |
| Alloys | are a type of homogeneous mixture of different elements. |
| Common types of alloys | Steel, Bronze, Brass |
| Physical properties | describe characteristics of matter that identify the substance without changing its identity. |
| Two kinds of physical properties | Extensive and Intensive properties |
| Is boiling point an intensive or extensive property? | Intensive property |
| Is volume an intensive or extensive property? | Extensive property |
| Is color an intensive or extensive property? | Intensive property |
| Is mass an intensive or extensive property? | Extensive property |
| Is temperature an intensive or extensive property? | Intensive property |
| Is size an intensive or extensive property? | Extensive property |
| Is luster an intensive or extensive property? | Intensive property |
| Is weight an intensive or extensive property? | Extensive property |
| Is hardness an intensive or extensive property? | Intensive property |
| Is length an intensive or extensive property? | Extensive property |
| Extensive property | Depends on the amount of matter in the substance |
| Intensive property | Does not depend on the amount of matter in the substance |
| Density= | Mass/Volume |
| 5 properties of water | Polarity, Cohesion, Adhesion, Surface Tension, High Specific Heat, Evaporative Cooline |
| Filtration | makes use of particle size |
| Decanting | makes use of density; the denser substance sinks to the bottom of the beaker and is removed making filtration easier. |
| Decantation of liquids | We can use decantation to separate two liquids with different density. |
| Decantation of a sediment | We can also separate a liquid from heavy sediments that sink in the bottom of the container. |
| Distillation | makes use of different boiling points in a mixture of miscible liquids There should be a minimum difference of 5 degrees Celsius. |
| Chromatography | uses attractive forces in a stationary phase and a mobile phase. |
| Crystallization | evaporating a solvent and leaving a solid solute behind |
| Centrifugation | uses density and a centrifuge machine. |
| Magnetism | Process in which a magnetically susceptible substance is separated from a mixture using a magnet. |
| Physical Change | Change of matter that occurs without changing the chemical composition of matter; reversible |
| Chemical change | Change of chemical composition of matter; irreversible |
| Claim | statement you believe to be true that solves a scientific question or problem |
| Evidence | Data or research you gathered, including observations, reading, videos, and other information |
| Reasoning | shows how the evidence answers the question or solves a problem |
| True or false: All nonzero digits are always significant zero's | True |
| True or false: Leading zeros are never significant | True |
| True or false: Leading zeros are significant | False |
| True or false: Sandwiched zeros are always significant | True |
| True or false: Sandwiched zeroes are never significant | False |
| True or false: Trailing zeroes are significant if there is a decimal and are not significant if there is no decimal. | True |
| how many sig figs are in this number 0.00709 | 3 |
| How many sig figs are in this number 3.44500 | 6 |
| How many sig figs are in this number 0.090 | 2 |
| How many sig figs are in this number 1.230 | 4 |

| Accuracy | Closeness to an accepted value. |
| Percent error | Calculated to define the accuracy of your data. |
| Precision | refers to how close measurements are to each other |
