Measurements are needed in many everyday activities. In kitchens you will find measures for volume (measuring cups), mass (scales and weights), and temperature (cooking thermometers). Accurate measurements are 11 important for scientific experiments. In a laboratory, make sure your measure meets your needs. 12 using any thermometer, double check that it covers the right temperature 13 for your activity or experiment. A garden thermometer, 14 , will burst if you try to use it for boiling liquids.
There are different systems of measures. Most scientists now use the International System of measures, with meters for length, kilograms for 15 , and seconds for time. If the measures in your experiment show other units, appropriate conversion tables for different systems may prove to be very useful.
