| Question | Answer |
| Why is measurement so important? | Without measurement it would be difficult for scientists to carry out experiments or form theories Measurement is used for quality control, safety, design and problem solving |
| what is length | Length is a measure of how long an object is or the distance between two points |
| what is the Standard Unit of length | The standard unit (SI) for length is the metre |
| what are the other units for length | Other units for length include: Centimetre (cm) Millimetre (mm) Kilometre (km) |
| convert 10cm to mm | 100mm |
| convert 100mm to cm | 10cm |
| convert 1000mm to m | 1m |
| convert 0.56m to cm | 56cm |
| what instruments are used to measure the length of a straight line | Metre stick (large lengths) Ruler Measuring tape Trundle wheel(large lengths) Vernier Callipers (diameter)(balls) |
| what errors can be made when measuring length | Zero error When the scale on the metre stick does not start at zero Error of parallax When the scale is read from the wrong angle |
| what Instrument ares used to measure the length of a curved lined | Opisometer |
| what is area | Area is the amount of surface enclosed within its lines |
| how do you Measure the area of a regular shaped object | you multiply the length by the width |
| Measuring area of an irregular shaped object | To calculate the area of an irregular shaped object, you draw the object on special graph paper Each square on the graph paper is 1cm by 1cm or 1cm² |
| what is volume | The amount of space that an object takes up |
| how do you Measure the volume of a regular shaped object | To calculate the volume of a regular shape you multiply the length by the width by the height |
| what is the Standard unit (SI) of area | The standard unit (SI) for area is the m² |
| what is the standard unit (SI) of volume | The standard unit (SI) for volume is the m³ |
| with what and how do you Measure the volume of a liquid | To calculate the volume of a liquid, you can use an graduated cylinder You must read: From the bottom of the meniscus (curved line) At eye level in order to get an accurate reading |
| with what do you Measure volume of an irregular shaped object | To calculate the volume of an irregular shaped object, you can use an overflow can |
| what is mass | The amount of matter in an object |
| what is the standard unit (SI) for mass | The standard unit (SI) for mass is the kilogram(Kg) |
| what is mass commonly measured in | Mass is commonly measured in grams (g) |
| what Instrument are used to measure mass | Electronic balance/scales. It can also be called a mass balance/scales |
| what is temperature | A measure of how hot or cold an object is |
| what is the standard unit (SI) of temperature | The standard unit (SI) for temperature is the Kelvin (K) |
| what is temperature also measured in | Temperature is commonly measured in Degrees Celsius (°C) |
| what is the instrument used to measure temperature | Thermometer |
| what is the standard unit(SI) of time | The standard unit (SI) for time is the second (S) |
| what are other units of Time | Other units of time include minutes(mins) and hours(hrs) |
| what Instrument is used to measure time | Timer/stopwatch |
