Mixtures & Solutions
5.5C/D-Mixtures & Solutions & More
| Term | Definition |
|---|---|
| Mixture | Two or more substances combined where they each keep their own properties and can be easily separated. |
| Dissolve | To mix evenly and break down and spread out in a liquid. |
| Filter, Strainer, or Sieve | Tool that is used to separate a mixture by trapping larger particles and allowing smaller particles to pass through. |
| Separate | To sort into individual parts or substances. |
| Solution | A mixture of one substance dissolved evenly in another substance, for example salt water or lemonade. |
| Evaporation | ‐‐‐‐‐ can be used to separate the substances in some solutions because the liquid evaporates and the solid is left behind. |
| Solubility | The ability of a solid to be dissolved in a liquid. |
| Physical Change | Make different without changing what a material is made of such as breaking a glass, melting an ice cube, or mixing red and yellow marbles. |
| Ingredient | One part of a mixture or solution. |
| Magnet | Tool that can be used to separate mixtures containing substances that are magnetic. |
| Evaporation | ‐‐‐‐‐ is the physical change in matter from a liquid to a gas. |
| Matter | Stuff that everything is made of, anything that has mass and takes up space. |
| Relative Density | Objects that are more dense than water will sink and objects that are less dense than water will float. |
| Insulator | Material that slows down or stops electric current or thermal (heat) energy from passing through. |
| Conductor | Material that allows electric current or thermal (heat) energy to pass through easily. |
| Solute | The substance being dissolved |
| Opaque | Not able to see through |
| Solvent | The substance doing the dissolving |
| Iron, nickel, cobalt and steel | Magnetic metals |
| Classify | To put into groups |
| Dissolve | Becomes so small you can no longer see it, but it is there. |
| Translucent | Sort of see though like a stained glass window or wax paper |
| Transparent | Totally see through |
| Insulators | Examples: paper, carboard, Styrofoam |
| Solid | Packed tightly together. Definite shape and volume |
| The number of molecules in matter that allows it to sink or float | Density |
| Takes the shape of the container | Liquid |
| When a solid changes to a liquid | Melting |
| A force that pulls objects towards each other | Gravity |
| Constant | To remain the same |
| The best soil for planting | Loam |
| Conclusion | The end of your investigation |
| Disperse | To spread out |
| The day-to-day conditions of our atmosphere | Weather |
| 2 or more items mixed together but you can separate easily | Mixture |
| Condensation | Clouds, fog, steam on a mirror |
| Coal | Made from swampy plants |
| Oil and natural gas | Made from dead plants and animals |
| Climate | The weather pattern that develops in an area of many years or decades. |
| The process of water going back and forth from Earth to the atmosphere | Water Cycle |
| Precipitation | Rain, snow, sleet or hail |
| Evaporation | Water changing from a liquid to a gas |
| Transpiration | Plants release water vapor into the atmosphere |
