Mass refers to the amount of matter in an object.
The base unit of mass in the metric system in the kilogram and is represented by kg.
Standard: 1 kilogram is equal to the mass of the International Prototype Kilogram (IPK), a platinum-iridium cylinder kept by the BIPM at Sèvres, France.
Metric Units
1 Kilogram (km) = 1000 Grams (g)
1 Gram (g) = 1000 Milligrams (mg)

Kilogram Prototype Image -

8. Measuring Mass
We will be using digital scales to find the mass of various objects.
The scale is set to zero using the “zero” or “tare” button before objects are placed on it. Then, objects are placed on the scale and you read the digital numerical value

9. Measuring Mass – Solids and Liquids
Measuring Solids
Irregularly shaped solids or powders may need the assistance of a container. When using containers to measure solids, you must be sure to zero the scale with the container before measuring the object’s mass. When using powders, a weighing tray is necessary.
Measuring Liquids
Measuring the mass of liquids always involves the assistance of a container. When using containers to measure liquids, you must be sure to zero the scale with the container before measuring the liquid’s mass. For this it is common to use a graduated cylinder or beaker

Which is larger?
A. 1 liter or 1 gallon
B. 1 liter or 1 quart
C. 1 milliliter or 1 fluid ounce
1 fl oz = ml
1 12-oz can of soda would equal approximately 355 ml.
1 gallon = 3.79 liters
It would take approximately 3 ¾ 1-liter bottles to equal a gallon.
1 quart = liters

13. Measuring Volume
We will be using graduated cylinders to find the volume of liquids and other objects.
Read the measurement based on the bottom of the meniscus or curve. When using a real cylinder, make sure you are eye-level with the level of the water.
What is the volume of water in the cylinder? _____mL
What causes the meniscus?
A concave meniscus occurs when the molecules of the liquid attract those of the container. The glass attracts the water on the sides.

Metric Units K C C K
Temperature refers to the degree of hotness of a body, substance, or medium; a physical property related to the average kinetic energy of the atoms or molecules of a substance
The base unit of mass in the metric system in the Kelvin and is represented by K.
Standard: The Kelvin scale begins from what is called absolute zero, the hypothetical point at which all molecular motion stops. ( ºC or ºF)
The Kelvin is not commonly used except in scientific endeavors. The most common unit used is degree Celcius represented by ºC
Common Metric Units
K = 0 ºC
K = 100 ºC

19. Measuring Temperature
We will be using thermometer to find the temperature of various objects.
The thermometers are placed on the object and then allowed time for the temperature to reach a steady state or show change.
For solids, you want to ensure the bulb is in contact with the desired substance or in the correct location in reference to a heat source.
For fluids, a rubber stopper may be used to keep the thermometer from touching the container and affecting the temperature reading.
