| Term | Definition |
|---|---|
| SI Unit | an abbreviation of the French word Système International; the International System Of Units (SI) is the metric system that is used universally as a standard for measurements. |
| gram | metric unit of mass |
| liter | metric unit of volume |
| meter | metric unit of length |
| graduated cylinder | measures liquid volume in milliliters - mls - more accurate for measuring liquid volume |
| beaker | A wide tool that has a small pouring lip; it is used for transporting and mixing solutions; it can measure liquid volume |
| How do you read a graduated cylinder properly? | view the height of the liquid in the cylinder with your eyes directly level with the liquid; Always read the measurement at the bottom of the meniscus. |
| displacement | the change in position of an object; a way to measure the volume of an irregularly shaped object |
| one millilter equals - 1 ml | one cubic centimeter - cm3 |
| triple beam balance | tool used to measure mass |
| digital scale | tool used to measure mass |
| mass | the amount of matter in an object; the amount of "stuff" an object is made up of |
| ruler/meter stick | used to measure length |
| quantitative | can be expressed with numbers or quantities; mass, length, volume and temperature are quantitative data |
| qualitative | not expressed with numbers and is gained through observation; color change, appearance change, texture change are examples |
| Which is larger a millimeter or a centimeter? | centimeter |
| Which is larger a millimeter or a kilometer? | kilometer |
| Does your mass or weight change when you go from planet to planet? | Your weight does; it is based upon the gravitational pull of the planet you are on |
| matter | anything that takes up space and has mass |
| volume | the amount of space something takes up |
| meniscus | occurs because of surface tension in the liquid and must be read at eye level |
| meniscus | read the point on the graduated scale that coincides with the bottom of the curved surface of the liquid while at eye level |
