| Measurement. | is a way to describe the world with numbers. It answers questions such as how much, how long, or how far. |
| Estimation. | it can help you make a rough measurement of an object. |
| Precision. | is a description of how close measurements are to each other. |
| Accuracy. | When you compare a measurement to the real, actual, or accepted value. |
| SI Units. | is an International System of Units established in 1960 by scientists to provide a worldwide standard of physical measurement for science, industry, and commerce. |
| Meter. | is the SI unit of length.One of these is about the length of a baseball bat. |
| Volume. | is the amount of space an object takes up.The cubic meter(m3 or cc) is the SI unit of volume. |
| Mass.- Kilogram. | is the amount of matter in an object.The kilogram is the SI unit for mass. One liter of water has a mass of about 1 kg. |
| Gram. | is a unit used to measure the mass of smaller objects. |
| Weight. | is a measurement of force. The SI unit for weight is the newton (N) Weight depends on gravity which can change depending where the object is located. |
| Which depends on gravity,mass o weight? | Weight. |
| What is volume by immersion? | is finding the volume of an irregularly shaped object by putting it in water and calculating the difference in water level before and after. |
| Kelvin. ( K scale ). | Temperature is measured in SI with the kelvin(K) scale. |
| Rate. | is the amount of change of one measurement in a given amount of time. |
| Table. | it displays information in rows and columns so that it is easier to read and understand. |
| Graph. | is used to collect,organize,and summarize data in a visual way. Three types of graphs are line, bar, and circle. |
| Line graph. | it shows the relationship between two variables.One variable is shown on the horizontal axis and one is shown on the vertical axis. |
| Bar graph. | it uses rectangular blocks, or bars, of varying sizes to show the relationships among variables. |
| Circle graph. | it shows the parts of a whole. (sometimes called pie graphs) |
| Model. | a representation of an object or event used as a tool for understanding the natural world. |
| Meterstick. | is a tool used in measuring length. |
| Cubic meter. | SI for measuring volume. |
| Celsius and Fahrenheit. | Are temperature scales. |
| To show the number of wins for your football team in your district you would use | Use a bar graph. |
| To show 25% on a circle graph the section must measure what angle? | 90 degrees. |
| The measurement 25.81 is precise to the nearest... | hundredth of a gram. |
| Accurate measurements. | Are very close to an accepted value |
| Round 33.755 to the nearest hundredth of a gram. | 33.76 |
| What quantity is measured using a balance? | Mass is measured. |
| What phase is water in at 60 degrees Celsius? | Liquid. |
| What is one-one thousanth of a meter? | a millimeter (mm). |
| Name 5 units of volume. | liter, milliliter, cubic centimeter, deciliter, cubic meter |
| 35.77 grams of Solid A are mixed with 95.3 grams of Solid B. What is the mass of the mixture with the correct number of significant digits. | 131.0 grams. |
| Calculate the volume of a cube 4cm by 4cm by 4cm. | 64 square centimeters. |
| Explain the difference between precision and accuracy. | Precision is how close measurements are to each other. Accuracy is a comparison of a measurement to an accepted value. |
| Newton.(N) | the SI for measuring weight. |
