Metric Measurement

volume To Measure the volume of a liquid: –Always use the smallest one that can fit the volume you need. Use a 10 ml cylinder if you only need 5 ml If you need 75 ml, use the 100 ml cylinder

Measuring with a Graduated Cylinder Measure at the lowest curve of the meniscus –Use a dropper to help to level off the amount wanted

What is the volume?

Using the Displacement method to measure the volume of a solid object Place 60 ml of water into a 100 ml GC. –Careful, slide the object into the GC. Record the new volume of the water. –Lets say the new volume is 65 ml –Subtract the original volume of 60 from the new volume of 65 ml –65 ml – 60 ml = 5 ml. The volume of the object is 5 ml

Displacement Method to determine volume

To measure distance or length metric ruler or meter stick Use a metric ruler or meter stick Each little line is 1 millimeter (mm) The thickness of a paperclip’s side 10 mm = 1 centimeter (cm) The thickness of your pinkie’s nail 10 cm = 1 decimeter (dm) The thickness of the palm of your hand 10 dm = 1 meter (m) (From fingertips to shoulder) 1 mm 1 cm 1 dm

Converting in the Metric System Kilo (k) = 1000 x a meter, liter or gram Deci (d) = 1/10 th of a meter Centi (c) = 1/100 th of a meter Milli (m) = 1/1000 th of a meter Micro (u) = 1/1,000,000 th of a meter or 1/1000 th of a millimeter Meter Liter Gram kilo deci centi milli micro

1. Convert centimeters to meters –Count how many spaces there are between the centimeters & meters and in which direction –…. 2 to the left –Now move the decimal place two places to the left – – meters kilo deci centi milli micro Meter Liter Gram

To MeasureTemperature: Use a Thermometer. We will only measure in degrees Celsius Important temperatures: Body temp ~ 37`C Room temp ~ 21 `C Water freezes at 0`C Water boils at 100`C
